Never try to take it apart. • Avoid dropping your calculator and subjecting it to strong impact. • Do not store the calculator or leave it in areas exposed to high temperatures or humidity, or large amounts of dust. When exposed to low temperatures, the calculator may require more time to display results and may even fail to operate. Correct operation will resume once the calculator is brought back to normal temperature. • Your calculator supports use of both alkaline batteries and rechargeable nickel-metal hydride batteries. Note that the amount of operation between charges provided by nickel-metal hydride batteries is shorter than the life of alkaline batteries. Use only batteries that are specifically recommended for this calculator. • Replace the main batteries once every one year regardless of how much the calculator is used during that period. Never leave dead batteries in the battery compartment. They can leak and damage the unit. Immediately remove nickel-metal hydride batteries from the calculator after their charge is used up. Leaving uncharged nickel-metal hydride batteries in the calculator can cause them to deteriorate. • Keep batteries out of the reach of small children. If swallowed, consult a physician immediately. • Avoid using volatile liquids such as thinner or benzine to clean the unit. Wipe it with a soft, dry cloth, or with a cloth that has been moistened with a solution of water and a neutral detergent and wrung out. • Always be gentle when wiping dust off the display to avoid scratching it. • In no event will the manufacturer and its suppliers be liable to you or any other person for any damages, expenses, lost profits, lost savings or any other damages arising out of loss of data and/or formulas arising out of malfunction, repairs, or battery replacement. It is up to you to prepare physical records of data to protect against such data loss. • Never dispose of batteries, the liquid crystal panel, or other components by burning them. • Be sure that the power switch is set to OFF when replacing batteries. • If the calculator is exposed to a strong electrostatic charge, its memory contents may be damaged or the keys may stop working. In such a case, perform the Reset operation to clear the memory and restore normal key operation. • If the calculator stops operating correctly for some reason, use a thin, pointed object to press the RESTART button on the back of the calculator. Note, however, that this clears all the data in calculator memory. • Note that strong vibration or impact during program execution can cause execution to stop or can damage the calculator’s memory contents. • Using the calculator near a television or radio can cause interference with TV or radio reception. • Before assuming malfunction of the unit, be sure to carefully reread this User’s Guide and ensure that the problem is not due to insufficient battery power, programming or operational errors. • Avoid contact with water and other liquids. Though your calculator is designed to be splash-resistant, note that splash-resistance is reduced if it is exposed to moisture, dirt, or dust while the battery compartment cover, USB port cap, SD card cap, or other opening is uncovered. Moisture getting into the calculator creates the risk of malfunction, fire, and electric shock. 1-3 • Do not swing the calculator around by its strap. Doing so creates the risk of calculator malfunction and personal injury. • Avoid opening the battery compartment cover, USB port cap, and SD card cap in areas where moisture or salt wind is present, when your hands are wet, when wearing wet gloves, etc. • Periodically check the battery compartment cover, USB port cap, SD card cap, and the areas around them for dirt, sand, and other foreign matter. If any of these areas are dirty, use a soft, clean, and dry cloth to wipe them. Note that even a minute particle of foreign matter (a single strand of hair, a single grain of sand, etc.) on a cover or cap contact surface creates the risk of moisture reaching the calculator interior. • If the calculator is exposed to large amounts of rain or other water, wipe it dry. Make sure that all moisture is removed before using the calculator again. • Do not use the calculator for long periods in the rain. • When closing the battery compartment cover, USB port cap, or SD card cap, inspect its gasket for cracks, damage, looseness, or other irregularities, and make sure that the cover or cap closes securely. • Take care to avoid dropping the calculator and do not leave it in an area that is outside the allowable operating temperature range. Such conditions can cause deterioration of splash and/or dust resistance. • Calculator accessories and options are not splash or dust resistant. • Subjecting the calculator to extreme shock may cause loss of splash and/or dust resistance. • CASIO COMPUTER CO., LTD. shall held in no way liable for any malfunction of or damage to the calculator or SD card being used, or for any corruption or deletion of memory contents due to problems related to invasion of moisture that may occur due to misuse by you. • CASIO COMPUTER CO., LTD. shall not be held responsible for any problems caused by exposure of this calculator to moisture. • A progress bar and/or a busy indicator appear on the display whenever the calculator is performing a calculation, writing to memory, or reading from memory. Busy indicator Progress bar Never press the RESTART button or remove the batteries from the calculator when the progress bar or busy indicator is on the display. Doing so can cause memory contents to be lost and can cause malfunction of the calculator. 1-4 Be sure to keep physical records of all important data! The large memory capacity of the unit makes it possible to store large amounts of data. You should note, however, that low battery power or incorrect replacement of the batteries that power the unit can cause the data stored in memory to be corrupted or even lost entirely. Stored data can also be affected by strong electrostatic charge or strong impact. It is up to you to keep back up copies of data to protect against its loss. Since this calculator employs unused memory as a work area when performing its internal calculations, an error may occur when there is not enough memory available to perform calculations. To avoid such problems, it is a good idea to leave 1 or 2 kbytes of memory free (unused) at all times. In no event shall CASIO Computer Co., Ltd. be liable to anyone for special, collateral, incidental, or consequential damages in connection with or arising out of the purchase or use of these materials. Moreover, CASIO Computer Co., Ltd. shall not be liable for any claim of any kind whatsoever against the use of these materials by any other party. 1-5 3. LCD and Key Back Lighting This calculator is equipped with LCD and key back lighting to make the keys and display easy to read, even in the dark. You can conserve battery power by limiting backlight operation to only when you need it. u To turn the backlight on or off Press !a(LIGHT) to toggle the backlight on and off. • Changing the Backlight On/Off Key You can configure the calculator so the backlight turns on when any key is pressed, instead of requiring the !a(LIGHT) to toggle the backlight on and off. For details, see “To specify the backlight key” (page 9-2). • Backlight duration You can configure backlight settings so it remains on or turns off after a specific period (30 seconds or 10 seconds) of calculator non-use. See “To specify the backlight duration” for details about the applicable operation procedure. • Backlight and Battery Life • Long-term backlight illumination can shorten battery life. • The table below shows approximate battery life values for a new set of alkaline batteries or a new set of nickel-metal hydride batteries when operations (1) through (3) are performed repeatedly at one-hour intervals, under a temperature of 25°C.

Splash Resistance, Dust Resistance, and Shock Resistance k Splash Resistance and Dust Resistance This calculator satisfies the requirements of the IP54* splash proof and dust proof protection levels defined by the International Electrotechnical Commission (IEC). * IP stands for “ingress protection”. The “5” of the left digit means Class 5 (no ingress of dust that affect device operation) protection against solid objects. The “4” means Class 4 protection against liquids (no harmful effects from water sprayed from all directions). k Shock Resistance This calculator has cleared independent testing by CASIO that was conducted based on the United States Defense Department MIL-STD-810G shock resistance performance test methods*. Test methods are those described below. Local testing by natural dropping of the calculator to the floor (P tile on concrete) from a height of 122 cm on six faces. Test data represents actual cumulative values based on CASIO standards, and do not constitute any guarantee of non-destruction of or nondamage to the actual product exterior. * Environmental laboratory test method (Method 516.6-Shock) of the United States Department of Defense MIL-STD-810G military standard, which requires passage by a total of at least five devices, which are drop tested from a height of 122 centimeters (4 feet) onto a plywood (lauan) drop zone, in groups of five, for a total of 26 drops (6 faces, 8 corners, 12 edges) Important! • Shock resistance testing assumes exposure to shock during normal everyday use. Subjecting the calculator to extreme shock may destroy it. • Even if exposure to shock does not result in calculator operational performance, it can cause scratching of the calculator’s display or other damage. • Splash resistance, dust resistance, and shock resistance testing of this calculator was performed using CASIO test methods. No guarantees are made concerning the ability of the calculator to be impervious to damage and/or malfunction. 1-7 5.

When you keep having problems… If you keep having problems when you are trying to perform operations, try the following before assuming that there is something wrong with the calculator. k Getting the Calculator Back to its Original Mode Settings 1. From the Main Menu, enter the SYSTEM mode. 2. Press 5(RSET). 3. Press 1(STUP), and then press 1(Yes). 4. Press Jm to return to the Main Menu. Now enter the correct mode and perform your calculation again, monitoring the results on the display. k Restart and Reset u Restart Should the calculator start to act abnormally, you can restart it by pressing the RESTART button. Note, however, that you should only use the RESTART button only as a last resort. Normally, pressing the RESTART button reboots the calculator’s operating system, so programs and other data in calculator memory is retained. RESTART button 2-16 Important! The calculator backs up user data (main memory) when you turn power off and loads the backed up data when you turn power back on. When you press the RESTART button, the calculator restarts and loads backed up data. This means that if you press the RESTART button after you edit a program or other data, any data that has not been backed up will be lost. u Reset Use reset when you want to delete all data currently in calculator memory and return all mode settings to their initial defaults. Before performing the reset operation, first make a written copy of all important data. For details, see “Reset” (page 9-3). k Low Battery Message If the following message appears on the display, immediately turn off the calculator and replace batteries as instructed. If you continue using the calculator without replacing batteries, power will automatically turn off to protect memory contents. Once this happens, you will not be able to turn power back on, and there is the danger that memory contents will be corrupted or lost entirely. • You will not be able to perform data communications operations after the low battery message appears. 2-17 Chapter 3 Manual Calculations 1. Basic Calculations k Arithmetic Calculations • Enter arithmetic calculations as they are written, from left to right. • Use the - key to input the minus sign before a negative value. • Calculations are performed internally with a 15-digit mantissa. The result is rounded to a 10digit mantissa before it is displayed. • For mixed arithmetic calculations, multiplication and division are given priority over addition and subtraction. Example Operation 56 × (–12) ÷ (–2.5) = 268.8 56*-12/-2.5w (2 + 3) × 102 = 500 !*( ( ) 2+3!/( ) )*10xw 2 + 3 × (4 + 5) = 29 2+3*!*( ( ) 4+5w*1 6 = 0.3 4×5 6/!*( ( ) 4*5!/( ) )w *1 Final closed parentheses (immediately before operation of the w key) may be omitted, no matter how many are required. k Number of Decimal Places, Number of Significant Digits, Normal Display Range [SET UP]- [Display] -[Fix] / [Sci] / [Norm] • Even after you specify the number of decimal places or the number of significant digits, internal calculations are still performed using a 15-digit mantissa, and displayed values are stored with a 10-digit mantissa. Use Rnd of the Numeric Calculation Menu (NUM) (page 3-10) to round the displayed value off to the number of decimal place and significant digit settings. • Number of decimal place (Fix) and significant digit (Sci) settings normally remain in effect until you change them or until you change the normal display range (Norm) setting. Example 1 100 ÷ 6 = 16.66666666... Condition Operation Display 100/6w 16.66666667 4 decimal places !m(SET UP) ff 1(Fix)ewJw *1 16.6667 5 significant digits !m(SET UP) ff 2(Sci)fwJw *1E+01 1.6667 Cancels specification !m(SET UP) ff 3(Norm)Jw 16.66666667 *1 Displayed values are rounded off to the place you specify. 3-1 3 Example 2 200 ÷ 7 × 14 = 400 Condition Operation 3 decimal places Calculation continues using display capacity of 10 digits Display 200/7*14w 400 !m(SET UP) ff 1(Fix)dwJw 400.000 200/7w * 14w 28.571 Ans × I 400.000 • If the same calculation is performed using the specified number of digits: 200/7w 28.571 The value stored internally is rounded off to the number of decimal places specified on the Setup screen. K6(g)4(NUM)4(Rnd)w * 14w 28.571 Ans × I 399.994 200/7w 28.571 You can also specify the number of decimal places for rounding of internal values for a specific calculation. (Example: To specify rounding to two decimal places) 6(g)1(RndFi)K,2!/( ) ) w * 14w RndFix(Ans,2) 28.570 Ans × I 399.980 k Calculation Priority Sequence This calculator employs true algebraic logic to calculate the parts of a formula in the following order: 1 Type A functions • Coordinate transformation Pol (x, y), Rec (r, θ) • Functions that include parentheses (such as derivatives, integrations, Σ, etc.) d/dx, d2/dx2, ∫dx, Σ, Solve, FMin, FMax, List→Mat, Fill, Seq, SortA, SortD, Min, Max, Median, Mean, Augment, Mat→List, P(, Q(, R(, t(, RndFix, logab • Composite functions*1, List, Mat, fn 2 Type B functions With these functions, the value is entered and then the function key is pressed. x2, x–1, x!, ° ’ ”, ENG symbols, angle unit °, r, g 3 Power/root ^(xy), x' 4 Fractions a b/c 5 Abbreviated multiplication format in front of π, memory name, or variable name. 2π, 5A, Xmin, H Start, etc. 6 Type C functions With these functions, the function key is pressed and then the value is entered. ', 3', log, In, ex, 10x, sin, cos, tan, sin–1, cos–1, tan–1, sinh, cosh, tanh, sinh–1, cosh–1, tanh–1, (–), d, h, b, o, Neg, Not, Det, Trn, Dim, Identity, Ref, Rref, Sum, Prod, Cuml, Percent, AList, Abs, Int, Frac, Intg, Arg, Conjg, ReP, ImP 3-2 7 Abbreviated multiplication format in front of Type A functions, Type C functions, and parenthesis. 2' 3, A log2, etc. 8 Permutation, combination nPr, nCr 9 Metric conversion commands 0 ×, ÷, Int÷, Rnd ! +, – @ Relational operators =, ≠, >, <, ≥, ≤ # And (logical operator), and (bitwise operator) $ Or, Xor (logical operator), or, xor, xnor (bitwise operator) *1 You can combine the contents of multiple function memory (fn) locations into composite functions. Specifying fn1(fn2), for example, results in the composite function fn1°fn2. A composite function can consist of up to five functions. Example 2 + 3 × (log sin2π2 + 6.8) = 22.07101691 (angle unit = Rad) 1 2 3 4 5 6 • You cannot use a differential, quadratic differential, integration, Σ, maximum/minimum value, Solve, RndFix or logab calculation expression inside of a RndFix calculation term. • When functions with the same priority are used in series, execution is performed from right to left. exIn 120 → ex{In( 120)} Otherwise, execution is from left to right. • Compound functions are executed from right to left. • Anything contained within parentheses receives highest priority. k Multiplication Operations without a Multiplication Sign You can omit the multiplication sign (×) in any of the following operations. • Before Type A functions (1 on page 3-2) and Type C functions (6 on page 3-2), except for negative signs Example 1 3, 2Pol(5, 12), etc. 2sin30, 10log1.2, 2' • Before constants, variable names, memory names Example 2 2π, 2AB, 3Ans, etc. • Before an open parenthesis Example 3 3(5 + 6), (A + 1)(B – 1), etc. Note If you execute a calculation that includes both division and multiplication operations in which a multiplication sign has been omitted, parentheses will be inserted automatically as shown in the examples below. 3-3 • When a multiplication sign is omitted immediately before an open parenthesis or after a closed parenthesis. Example 1 6 ÷ 2(1 + 2) → 6 ÷ (2(1 + 2)) 6 ÷ A(1 + 2) → 6 ÷ (A(1 + 2)) 1 ÷ (2 + 3)sin30 → 1 ÷ ((2 + 3)sin30) • When a multiplication sign is omitted immediately before a variable, a constant, etc. Example 2 6 ÷ 2π → 6 ÷ (2π) 2 ÷ 2' 2 → 2 ÷ (2' 2) 4π ÷ 2π → 4π ÷ (2π) k Overflow and Errors Exceeding a specified input or calculation range, or attempting an illegal input causes an error message to appear on the display. Further operation of the calculator is impossible while an error message is displayed. For details, see the “Error Message Table” on page α-4. • Most of the calculator’s keys are inoperative while an error message is displayed. Press J to clear the error and return to normal operation. k Memory Capacity Each time you press a key, either one byte or two bytes is used. Some of the functions that require one byte are: b, c, d, !h(sin), !i(cos), !j(tan), and !x('). Some of the functions that take up two bytes are d/dx(, Mat, Xmin, If, For, Return, and SortA. 2. Special Functions k Calculations Using Variables Example Operation Display 193.2!K(→)a1(A-E)1(A)w 193.2 193.2 ÷ 23 = 8.4 1(A)/23w 8.4 193.2 ÷ 28 = 6.9 1(A)/28w 6.9 k Memory u Variables (Alpha Memory) This calculator comes with 28 variables as standard. You can use variables to store values you want to use inside of calculations. Variables are identified by single-letter names, which are made up of the 26 letters of the alphabet, plus r and θ. The maximum size of values that you can assign to variables is 15 digits for the mantissa and 2 digits for the exponent. • Variable contents are retained even when you turn power off. 3-4 u To assign a value to a variable [value] !K(→) [variable name] w Example 1 To assign 123 to variable A Abcd!K(→) a1(A-E)1(A)w Example 2 To add 456 to variable A and store the result in variable B Aa1(A-E)1(A)+efg !K(→)a1(A-E)2(B)w u To assign the same value to more than one variable [value]!K(→) [first variable name]a6(SYBL)3(~) [last variable name]w • You cannot use “r” or “θ ” as a variable name. Example To assign a value of 10 to variables A through F Aba!K(→)a1(A-E) 1(A)J6(SYBL)3(~)J 2(F-J)1(F)w u String Memory You can store up to 20 strings (named Str 1 to Str 20) in string memory. Stored strings can be output to the display or used inside functions and commands that support the use of strings as arguments. For details about string operations, see “Strings” (page 6-20). Example To assign string “ABC” to Str 1 and then output Str 1 to the display Aa6(SYBL)2(")J 1(A-E)1(A)2(B)3(C)J 6(SYBL)2(")!K(→)!K(VARS) 6(Str)bw 6(Str)bw String is displayed justified left. 3-5 u Function Memory [OPTN]-[FMEM] Function memory is convenient for temporary storage of often-used expressions. • {STO}/{RCL}/{fn}/{SEE} ... {function store}/{function recall}/{function area specification as a variable name inside an expression}/{function list} u To store a function Example To store the function (A+B) (A–B) as function memory number 1 !*( ( )a1(A-E)1(A)+ a2(B)!/( ) ) !*( ( )a1(A-E)1(A)a2(B)!/( ) ) K6(g)6(g)3(FMEM) 1(STO)bw JJJ • If the function memory number to which you store a function already contains a function, the previous function is replaced with the new one. • You can also use !K(→) to store a function in function memory in a program. In this case, you must enclose the function inside of double quotation marks. u To recall a function Example To recall the contents of function memory number 1 AK6(g)6(g)3(FMEM) 2(RCL)bw • The recalled function appears at the current location of the cursor on the display. u To recall a function as a variable Ad!K(→)a1(A-E)1(A)w b!K(→)a1(A-E)2(B)w K6(g)6(g)3(FMEM)3(fn) b+cw 3-6 u To display a list of available functions K6(g)6(g)3(FMEM) 4(SEE) u To delete a function Example To delete the contents of function memory number 1 A K6(g)6(g)3(FMEM) 1(STO)bw • Executing the store operation while the display is blank deletes the function in the function memory you specify. k Answer Function The Answer Function automatically stores the last result you calculated by pressing w (unless the w key operation results in an error). The result is stored in the answer memory. • The largest value that the answer memory can hold is 15 digits for the mantissa and 2 digits for the exponent. • Answer memory contents are not cleared when you press the A key or when you switch power off. u To use the contents of the answer memory in a calculation Example 123 + 456 = 579 789 – 579 = 210 Abcd+efgw hij-Kw 3-7 k Performing Continuous Calculations Answer memory also lets you use the result of one calculation as one of the arguments in the next calculation. Example 1÷3= 1÷3×3= Ab/dw (Continuing)*dw Continuous calculations can also be used with Type B functions (x2, x–1, x!, on page 3-2), +, –, ^(xy), x', ° ’ ”, etc. 3.

Ran# returns a single random number, while RanList# returns multiple random numbers in list form. The following shows the syntaxes of Ran# and RanList#. Ran# [a] 1<a<9 RanList# (n [,a]) 1 < n < 999 • n is the number of trials. RanList# generates the number of random numbers that corresponds to n and displays them on the ListAns screen. A value must be input for n. • “a” is the randomization sequence. Random numbers are returned if nothing is input for “a”. Entering an integer of 1 through 9 for a will return the corresponding sequential random number. • Executing the function Ran# 0 initializes the sequences of both Ran# and RanList#. The sequence also is initialized when a sequential random number is generated with a different sequence of the previous execution using Ran# or RanList#, or when generating a random number. Ran# Examples Example Operation K6(g)3(PROB)4(RAND) 1(Ran#)w Ran# (Generates a random number.)

RanInt# (A, B [,n]) A<B |A|,|B| < 1E10 B – A < 1E10 1 < n < 999 • A is the start value and B is the end value. Omitting a value for n returns a generated random number as-is. Specifying a value for n returns the specified number of random values in list form. Example Operation RanInt# (1, 5) (Generates one random integer from 1 and 5.) K6(g)3(PROB)4(RAND)2(Int) 1,5!/( ) )w RanInt# (1, 10, 5) (Generates five random integers from 1 to 10 and displays the result on the ListAns screen.)

The following is the syntax for using the Solve function. Solve( f(x), n, a, b) (a: lower limit, b: upper limit, n: initial estimated value) An error (Time Out) occurs when there is no convergence of the solution. • You cannot use a quadratic differential, Σ, maximum/minimum value or Solve calculation expression inside of any of the above functions. • Pressing A during calculation of Solve (while the cursor is not shown on the display) interrupts the calculation. 3-20 k Solving an f(x) Function [OPTN]-[CALC]-[SolvN] You can use SolvN to solve an f(x) function using numerical analysis. The following is the input syntax. SolveN (left side [=right side] [,variable] [, lower limit, upper limit]) • The right side, variable, lower limit and upper limit all can be omitted. • “left side[=right side]” is the expression to be solved. Supported variables are A through Z, r, and θ. When the right side is omitted, solution is perform using right side = 0. • The variable specifies the variable within the expression to be solved for (A through Z, r, θ). Omitting a variable specification cause X to be used as the variable. • The lower limit and upper limit specify the range of the solution. You can input a value or an expression as the range. • The following functions cannot be used within any of the arguments. Solve(, d2/dx2, FMin(, FMax(, Σ( Up to 10 calculation results can be displayed simultaneously in ListAns format. • The message “No Solution” is displayed if no solution exists. • The message “More solutions may exist.” is displayed when there may be solutions other than those displayed by SolvN.

Other variables (A through Z excluding X, r, Ƨ) are treated as constants, and the value currently assigned to that variable is applied during the calculation. • Input of the tolerance (tol) value and the closing parenthesis can be omitted. If you omit tolerance (tol) value, the calculator automatically uses a value for tol as 1E–10. • Specify a tolerance (tol) value of 1E–14 or greater. An error (Time Out) occurs whenever no solution that satisfies the tolerance value can be obtained. • Pressing A during calculation of a differential (while the cursor is not shown on the display) interrupts the calculation. • Inaccurate results and errors can be caused by the following: - discontinuous points in x values - extreme changes in x values - inclusion of the local maximum point and local minimum point in x values 3-22 - inclusion of the inflection point in x values - inclusion of undifferentiable points in x values - differential calculation results approaching zero • Always use radians (Rad mode) as the angle unit when performing trigonometric differentials. • You cannot use a differential, quadratic differential, integration, Σ, maximum/minimum value, Solve, RndFix or logab calculation expression inside a differential calculation term. k Quadratic Differential Calculations [OPTN]-[CALC]-[d2/dx2] After displaying the function analysis menu, you can input quadratic differentials using the following syntax. K4(CALC)3(d2/dx2) f(x),a,tol!/( ) ) (a: differential coefficient point, tol: tolerance) Quadratic differential calculations produce an approximate differential value using the following second order differential formula, which is based on Newton’s polynomial interpretation. In this expression, values for “sufficiently small increments of h” are used to obtain a value that approximates f"(a). Example To determine the quadratic differential coefficient at the point where x = 3 for the function y = x3 + 4x2 + x – 6 Here we will use a tolerance tol = 1E – 5 Input the function f(x).

Positive part (S ) Negative part (S ) ∫ b a f(x)dx = ∫ c a f(x)dx + Positive part (S) ∫ b c f(x)dx Negative part (S) (2) When minute fluctuations in integration divisions produce large fluctuations in integration values, calculate the integration divisions separately (divide the large fluctuation areas into smaller divisions), and then add the results together. ∫ b a f(x)dx = ∫ x a 1 f(x)dx + ∫ x 2 x f(x)dx +.....+ 1 ∫ b x f(x)dx 4 • Pressing A during calculation of an integral (while the cursor is not shown on the display) interrupts the calculation. • Always use radians (Rad mode) as the angle unit when performing trigonometric integrations. • An error (Time Out) occurs whenever no solution that satisfies the tolerance value can be obtained. Integration Calculation Precautions • In the function f(x), only X can be used as a variable in expressions. Other variables (A through Z excluding X, r, Ƨ) are treated as constants, and the value currently assigned to that variable is applied during the calculation. • Input of “tol” and closing parenthesis can be omitted. If you omit “tol,” the calculator automatically uses a default value of 1E–5. • Integration calculations can take a long time to complete. • You cannot use a differential, quadratic differential, integration, Σ, maximum/minimum value, Solve, RndFix or logab calculation expression inside of an integration calculation term. 3-25 k Σ Calculations [OPTN]-[CALC]-[Σ(] To perform Σ calculations, first display the function analysis menu, and then input the values using the syntax below.

Inputting and Editing a List When you enter the STAT mode, the “List Editor” will appear first. You can use the List Editor to input data into a list and to perform a variety of other list data operations. u To input values one-by-one Use the cursor keys to move the highlighting to the list name, sub name or cell you want to select. Note that c does not move the highlighting to a cell that does not contain a value. The screen automatically scrolls when the highlighting is located at either edge of the screen. The following example is performed starting with the highlighting located at Cell 1 of List 1. 1. Input a value and press w to store it in the list. dw • The highlighting automatically moves down to the next cell for input. 2. Input the value 4 in the second cell, and then input the result of 2 + 3 in the next cell. ewc+dw • You can also input the result of an expression or a complex number into a cell. • You can input values up to 999 cells in a single list. 4-1 4 u To batch input a series of values 1. Use the cursor keys to move the highlighting to another list. 2. Input a left brace ( { ), and then enter the values, separated by commas. After inputting all of the values you want, input a right brace ( } ). !a(CATALOG)a6(SYBL)4(9) c~c( { )wg,h,i !a(CATALOG)c( } )w 3. Press w to store all of the values in your list. w • Remember that a comma separates values, so you should not input a comma after the final value of the set you are inputting. Right: {34, 53, 78} Wrong: {34, 53, 78,} You can also use list names inside of a mathematical expression to input values into another cell. The following example shows how to add the values in each row in List 1 and List 2, and input the result into List 3. 1. Use the cursor keys to move the highlighting to the name of the list where you want the calculation results to be input. 2. Press K and input the expression.

Use the cursor keys to move the highlighting to the cell you want to delete. 2. Press 6(g)3(DEL) to delete the selected cell and cause everything below it to be shifted up. • The cell delete operation does not affect cells in other lists. If the data in the list whose cell you delete is somehow related to the data in neighboring lists, deleting a cell can cause related values to become misaligned. u To delete all cells in a list Use the following procedure to delete all the data in a list. 1. Use the cursor keys to move the highlighting to any cell of the list whose data you want to delete. 2. Pressing 6(g)4(DEL • A) causes a confirmation message to appear. 3. Press 1(Yes) to delete all the cells in the selected list or 6(No) to abort the delete operation without deleting anything. u To insert a new cell 1. Use the cursor keys to move the highlighting to the location where you want to insert the new cell. 2. Press 6(g)5(INS) to insert a new cell, which contains a value of 0, causing everything below it to be shifted down. • The cell insert operation does not affect cells in other lists. If the data in the list where you insert a cell is somehow related to the data in neighboring lists, inserting a cell can cause related values to become misaligned. k Naming a List You can assign List 1 through List 26 “sub names” of up to eight bytes each. u To name a list 1. On the Setup screen, highlight “Sub Name” and then press 1(On)J. 2. Use the cursor keys to move the highlighting to the SUB cell of the list you want to name. 4-3 3. Type in the name and then press w. Example: YEAR a5(U-Z)5(Y)J1(A-E)5(E) 1(A)J4(P-T)3(R) • The following operation displays a sub name in the RUN • MAT mode.

The highlighting can be located in any cell of the list. u To sort a single list Ascending order 1. While the lists are on the screen, press 6(g)1(TOOL)1(SRT • A). 2. The prompt “How Many Lists?:” appears to ask how many lists you want to sort. Here we will input 1 to indicate we want to sort only one list. bw 3. In response to the “Select List List No:” prompt, input the number of the list you want to sort. bw Descending order Use the same procedure as that for the ascending order sort. The only difference is that you should press 2(SRT • D) in place of 1(SRT • A). u To sort multiple lists You can link multiple lists together for a sort so that all of their cells are rearranged in accordance with the sorting of a base list. The base list is sorted into either ascending order or descending order, while the cells of the linked lists are arranged so that the relative relationship of all the rows is maintained. 4-4 Ascending order 1. While the lists are on the screen, press 6(g)1(TOOL)1(SRT • A). 2. The prompt “How Many Lists?:” appears to ask how many lists you want to sort. Here we will sort one base list linked to one other list, so we should input 2. cw 3. In response to the “Select Base List List No:” prompt, input the number of the list you want to sort into ascending order. Here we will specify List 1. bw 4. In response to the “Select Second List List No:” prompt, input the number of the list you want to link to the base list. Here we will specify List 2. cw Descending order Use the same procedure as that for the ascending order sort. The only difference is that you should press 2(SRT • D) in place of 1(SRT • A). • You can specify a value from 1 to 6 as the number of lists for sorting. • If you specify a list more than once for a single sort operation, an error occurs. An error also occurs if lists specified for sorting do not have the same number of values (rows). 2. Manipulating List Data List data can be used in arithmetic and function calculations. In addition, various list data manipulation functions make manipulation of list data quick and easy. You can use list data manipulation functions in the RUN • MAT, STAT and PRGM modes. k Accessing the List Data Manipulation Function Menu All of the following examples are performed after entering the RUN • MAT mode.

For example, specifying “AList 1 → List 2” will store the result of AList 1 in List 2. • The number of cells in the new AList is one less than the number of cells in the original list. • An error occurs if you execute AList for a list that has no data or only one data item. 3. Arithmetic Calculations Using Lists You can perform arithmetic calculations using two lists or one list and a numeric value. List Numeric Value + − × ÷ ListAns Memory List = Numeric Value List Calculation results are stored in ListAns Memory. k Error Messages • A calculation involving two lists performs the operation between corresponding cells. Because of this, an error occurs if the two lists do not have the same number of values (which means they have different “dimensions”). • An error occurs whenever an operation involving any two cells generates a mathematical error. k Inputting a List into a Calculation There are three methods you can use to input a list into a calculation. • Specification of the list number of a list created with List Editor. • Specification of the sub name of a list created with List Editor. • Direct input of a list of values. u To specify the list number of a list created with List Editor 1. In the RUN • MAT mode, perform the following key operation. AK1(LIST)1(List) • Enter the “List” command. 2. Enter the list number (integer from 1 to 26) you want to specify. u To specify the sub name of a list created with List Editor 1. In the RUN • MAT mode, perform the following key operation. AK1(LIST)1(List) • Enter the “List” command. 2. Enter the sub name of the list you want to specify, enclosed in double quotes (" "). Example: "QTY" 4-10 u To directly input a list of values You can also directly input a list of values using {, }, and ,. Example To input the list: 56, 82, 64 !a(CATALOG)a6(SYBL)4(9) c~c( { )wfg,ic,ge !a(CATALOG)c( } )w u To assign the contents of one list to another list Use !K(→) to assign the contents of one list to another list. Example To assign the contents of List 3 (41, 65, 22) to List 1 K1(LIST)1(List)d!K(→)1(List)bw u To recall the value in a specific list cell You can recall the value in a specific list cell and use it in a calculation. Specify the cell number by enclosing it inside square brackets. Example To calculate the sine of the value stored in Cell 3 of List 2 sK1(LIST)1(List)c!a(CATALOG)a6(SYBL)4(9) c~c( [ )wd!a(CATALOG)c( ] )ww u To input a value into a specific list cell You can input a value into a specific list cell inside a list. When you do, the value that was previously stored in the cell is replaced with the new value you input. Example To input the value 25 into Cell 2 of List 3 cf!K(→)K1(LIST)1(List)d!a(CATALOG) a6(SYBL)4(9)c~c( [ )wc!a(CATALOG)c( ] )ww k Recalling List Contents Example To recall the contents of List 1 K1(LIST)1(List)bw • The above operation displays the contents of the list you specify and also stores them in ListAns Memory. You can then use the ListAns Memory contents in a calculation. 4-11 u To use list contents in ListAns Memory in a calculation Example To multiply the list contents in ListAns Memory by 36 K1(LIST)1(List)!K*dgw • The operation K1(LIST)1(List)!K recalls ListAns Memory contents. • This operation replaces current ListAns Memory contents with the result of the above calculation. k Performing Scientific Function Calculations Using a List Lists can be used just as numeric values are in scientific function calculations. When the calculation produces a list as a result, the list is stored in ListAns Memory. Example To use List 3 41 65 to perform sin (List 3) 22 Use radians as the angle unit. !h(sin)K1(LIST)1(List)dw 4.

In each case, new data values were input in order to highlight the particular characteristics of the graph being drawn. Note that when you try to draw a similar graph, the unit uses data values that you have input using the List function. Because of this, the graphs that appear on the screen when you perform a graphing operation will probably differ somewhat from those shown in this manual. 1. Before Performing Statistical Calculations Entering the STAT mode from the Main Menu displays the List Editor screen. You can use the List Editor screen to input statistical data and perform statistical calculations. Use f, c, d and e to move the highlighting around the lists. Once you input data, you can use it to produce a graph and check for tendencies. You can also use a variety of different regression calculations to analyze the data. • For information about using the statistical data lists, see “Chapter 4 List Function”. k Changing Graph Parameters Use the following procedures to specify the graph draw/non-draw status, the graph type, and other general settings for each of the graphs in the graph menu (GPH1, GPH2, GPH3). While the statistical data list is on the display, press 1(GRPH) to display the graph menu, which contains the following items. • {GPH1}/{GPH2}/{GPH3} ... graph {1}/{2}/{3} drawing*1 • {SEL} ... {simultaneous graph (GPH1, GPH2, GPH3) selection} You can specify the multiple graphs. • {SET} ... {graph settings (graph type, list assignments)} *1 The initial default graph type setting for all the graphs (Graph 1 through Graph 3) is scatter diagram, but you can change to one of a number of other graph types. 1. General graph settings [GRPH]-[SET] This section describes how to use the general graph settings screen to make the following settings for each graph (GPH1, GPH2, GPH3). • Graph Type The initial default graph type setting for all the graphs is scatter graph. You can select one of a variety of other statistical graph types for each graph. 5-1 5 • List The initial default statistical data is List 1 for single-variable data, and List 1 and List 2 for paired-variable data. You can specify which statistical data list you want to use for x-data and y-data. • Frequency Normally, each data item or data pair in the statistical data list is represented on a graph as a point. When you are working with a large number of data items however, this can cause problems because of the number of plot points on the graph. When this happens, you can specify a frequency list that contains values indicating the number of instances (the frequency) of the data items in the corresponding cells of the lists you are using for x-data and y-data. Once you do this, only one point is plotted for the multiple data items, which makes the graph easier to read. • Mark Type This setting lets you specify the shape of the plot points on the graph. u To display the general graph settings screen [GRPH]-[SET] Pressing 1(GRPH)6(SET) displays the general graph settings screen. • StatGraph (statistical graph specification) • {GPH1}/{GPH2}/{GPH3} ... graph {1}/{2}/{3} • Graph Type (graph type specification) • {Scat}/{xy}/{NPP}/{Pie} ... {scatter diagram}/{xy line graph}/{normal probability plot}/{pie graph} • {Hist}/{Box}/{Bar}/{N·Dis}/{Brkn} ... {histogram}/{med-box graph}/{bar graph}/{normal distribution curve}/{broken line graph} • {X}/{Med}/{X^2}/{X^3}/{X^4} ... {linear regression graph}/{Med-Med graph}/{quadratic regression graph}/{cubic regression graph}/{quartic regression graph} • {Log}/{Exp}/{Pwr}/{Sin}/{Lgst} ... {logarithmic regression graph}/{exponential regression graph}/{power regression graph}/{sinusoidal regression graph}/{logistic regression graph} • XList (x-axis data list)/YList (y-axis data list) • {List} ... {List 1 to 26} • Frequency (number of times a value occurs) • {1} ... {1-to-1 plot} • {List} ... {List 1 to 26} • Mark Type (plot mark type) • {}/{×}/{•} ... scatter diagram plot points When “Pie” (pie graph) is selected as the Graph Type: • Data (Specifies the list to be used as graph data.) • {LIST} ... {List 1 to List 26} • Display (pie graph value display setting) • {%}/{Data} ... For each data element {display as percentage}/{display as value} 5-2 • % Sto Mem (Specifies storage of percentage values to a list.) • {None}/{List} ... For percentage values: {Do not store to list}/{Specify List 1 to 26 and store} When “Box” (med-box graph) is selected as the Graph Type: • Outliers (outliers specification) • {On}/{Off} ... {display}/{do not display} Med-Box outliers When “Bar” (bar graph) is selected as the Graph Type: • Data1 (first stick data list) • {LIST} ... {List 1 to 26} • Data2 (second stick data list)/Data3 (third stick data list) • {None}/{LIST} ... {none}/{List 1 to 26} • Stick Style (stick style specification) • {Leng}/{HZtl} ... {length}/{horizontal} 2. Graph draw/non-draw status [GRPH]-[SEL] The following procedure can be used to specify the draw (On)/non-draw (Off) status of each of the graphs in the graph menu. u To specify the draw/non-draw status of a graph 1. Pressing 1(GRPH)4(SEL) displays the graph On/Off screen. • Note that the StatGraph1 setting is for Graph 1 (GPH1 of the graph menu), StatGraph2 is for Graph 2, and StatGraph3 is for Graph 3. 2. Use the cursor keys to move the highlighting to the graph whose status you want to change, and press the applicable function key to change the status. • {On}/{Off} ... {On (draw)}/{Off (non-draw)} • {DRAW} ... {draws all On graphs} 3. To return to the graph menu, press J. k Statistical Graph View Window (V-Window) Settings View Window settings specify the range that needs to be specified when you draw a graph. View Window settings are configured automatically in the case of statistical graphs (when “Auto” is specified for the “Stat Wind” setting). Note • For statistical graphing, you can select either “Auto” or “Manual” for the “Stat Wind” (page 2-15) item on the setup screen to specify the View Window setting method. For information about switching between auto and manual, see “To change a mode setup” (page 2-14). • For the View Window setting procedures you need to perform while “Manual” is selected as the “Stat Wind” setting, see “Configuring View Window Settings Manually” in this manual (page 5-16). • Pie graphs are always displayed in accordance with a predetermined format, regardless of the current View Window settings. 5-3 2. Calculating and Graphing Single-Variable Statistical Data Single-variable data is data with only a single variable. If you are calculating the average height of the members of a class for example, there is only one variable (height). Single-variable statistics include distribution and sum. The following types of graphs are available for single-variable statistics. You can also use the procedures under “Changing Graph Parameters” on page 5-1 to make the settings you want before drawing each graph. k Normal Probability Plot This plot compares the data accumulated ratio with a normal distribution accumulated ratio. XList specifies the list where data is input, and Mark Type is used to select from among the marks { / × / • } you want to plot. Press A, J or !J(QUIT) to return to the statistical data list. k Pie Graph You can draw a pie graph based on the data in a specific list. The maximum number of graph data items (list lines) is 20. The graph is labeled A, B, C, and so on, corresponding to lines 1, 2, 3, and so on of the list used for the graph data. When “%” is selected for the “Display” setting on the general graph settings screen (page 5-2), a value showing the percentage is displayed for each of the alphabetic label letters. k Histogram XList specifies the list where the data is input, while Freq specifies the list where the data frequency is input. 1 is specified for Freq when frequency is not specified. ⇒ w(DRAW) 5-4 The display screen appears as shown above before the graph is drawn. At this point, you can change the Start and Width values. k Med-box Graph This type of graph lets you see how a large number of data items are grouped within specific ranges. A box minX encloses all the data in an area from the first quartile (Q1) to the third quartile (Q3), with a line drawn at the median (Med). Lines (called whiskers) extend from either end of the box up to the minimum (minX) and maximum (maxX) of the data. From the statistical data list, press 1(GRPH) to display the graph menu, press 6(SET), and then change the graph type of the graph you want to use (GPH1, GPH2, GPH3) to med-box graph. Q1 Med Q3 maxX To plot the data that falls outside the box, first specify “MedBox” as the Graph Type. Then, on the same screen you use to specify the graph type, turn the Outliers item “On”, and draw the graph. • Changing the “Q1Q3 Type” setting on the Setup screen can cause the Q1 and Q3 positions to change, even when a Med-box graph is drawn based on a single list. k Bar Graph You can specify up to three lists for drawing a bar graph. The graph is labeled [1], [2], [3], and so on, corresponding to lines 1, 2, 3, and so on of the list used for the graph data. • Any of the following causes an error and cancels bar graph drawing. - A Condition ERROR occurs when drawing of multiple graphs is specified using the graph On/Off screen (page 5-3), and bar graph is specified for one of the graphs and a different graph type is specified for another graph. - A Dimension ERROR occurs when you draw a graph with two or three lists specified and the specified lists have a different number of list elements. - A Condition ERROR occurs when lists are assigned for Data1 and Data3, while “None” is specified for Data2. 5-5 k Normal Distribution Curve The normal distribution curve is graphed using the normal distribution function. XList specifies the list where the data is input, while Freq specifies the list where the data frequency is input. 1 is specified for Freq when frequency is not specified. k Broken Line Graph Lines connect center points of a histogram bar. XList specifies the list where the data is input, while Freq specifies the list where the data frequency is input. 1 is specified for Freq when frequency is not specified. ⇒ w(DRAW) The display screen appears as shown above before the graph is drawn. At this point, you can change the Start and Width values. k Displaying the Calculation Results of a Drawn Single-Variable Graph Single-variable statistics can be expressed as both graphs and parameter values. When these graphs are displayed, the single-variable calculation results appear as shown to the right when you press 1(1VAR). • Use c to scroll the list so you can view the items that run off the bottom of the screen. The following describes the meaning of each of the parameters. x¯ .................. mean Σx ................ sum Σx2 ............... sum of squares Q1 ................ first quartile σx ................. population standard deviation maxX ............ maximum sx ................. sample standard deviation Mod:n ..........number of data mode items Med .............. median Q3 ................ third quartile Mod .............. mode Mod:F ..........data mode frequency n ..................number of data items minX .............minimum 5-6 • Press 6(DRAW) to return to the original single-variable statistical graph. • When Mod has multiple solutions, they are all displayed. • You can use the Setup screen’s “Q1Q3 Type” setting to select either “Std” (standard calculation) or “OnData” (French calculation) for the Q1 and Q3 calculation mode. For details about calculation methods while “Std” or “OnData” is selected, see “Calculation Methods for the Std and OnData Settings” below. k Calculation Methods for the Std and OnData Settings Q1 and Q3 can be calculated in accordance with the Setup screen’s “Q1Q3 Type” setting as described below. u Std With this calculation method, processing depends on whether the number of elements n in the population is an even number or odd number. When the number of elements n is an even number: Using the center point of the total population as the reference, the population elements are divided into two groups: a lower half group and an upper half group. Q1 and Q3 then become the values described below. Q1 = {median of the group of Q3 = {median of the group of n 2 n 2 Center Point 1 2 3 items from the bottom of the population} items from the top of the population} Center Point 4 5 Center Point 6 7 8 4+5 = Median 2 2+3 = Q1 2 6+7 = Q3 2 When the number of elements n is an odd number: Using the median of the total population as the reference, the population elements are divided into two groups: a lower half group (values less than the median) and an upper half group (values greater than the median). The median value is excluded. Q1 and Q3 then become the values described below. n–1 Q1 = {median of the group of items from the bottom of the population} 2 n–1 Q3 = {median of the group of items from the top of the population} 2 • When n = 1, Q1 = Q3 = population center point. 5-7 Center Point 1 2 Center Point 3 4 5 6 7 8 9 Median 2+3 = Q1 2 7+8 = Q3 2 u OnData The Q1 and Q3 values for this calculation method are described below. Q1 = {value of element whose cumulative frequency ratio is greater than 1/4 and nearest to 1/4} Q3 = {value of element whose cumulative frequency ratio is greater than 3/4 and nearest to 3/4} The following shows an actual example of the above. (Number of Elements: 10) Data Value Frequency Cumulative Frequency Cumulative Frequency Ratio 1 1 1 1/10 = 0.1 2 1 2 2/10 = 0.2 3 2 4 4/10 = 0.4 4 3 7 7/10 = 0.7 5 1 8 8/10 = 0.8 6 1 9 9/10 = 0.9 7 1 10 10/10 = 1.0 • 3 is the value of whose cumulative frequency ratio is greater than 1/4 and nearest to 1/4, so Q1 = 3. • 5 is the value of whose cumulative frequency ratio is greater than 3/4 and nearest to 3/4, so Q3 = 5. Reference Point (0.25) 0.1 0.2 1 2 Reference Point (0.75) 0.4 3 3 4 4 Q1 0.7 0.8 0.9 1.0 4 5 6 7 Q3 5-8 3.

From the Main Menu, enter the STAT mode. 2. Input the data into a list, and plot the scatter diagram. 3. Select the regression type, execute the calculation, and display the regression parameters. 4. Draw the regression graph. 5-9 Example Input the two sets of data shown below and plot the data on a scatter diagram. Next, perform logarithmic regression on the data to display the regression parameters, and then draw the corresponding regression graph. 0.5, 1.2, 2.4, 4.0, 5.2 (xList) –2.1, 0.3, 1.5, 2.0, 2.4 (yList) 1 m STAT 2 a.fwb.cwc.ewewf.cwe -c.bwa.dwb.fwcwc.ew 1(GRPH)6(SET)c1(Scat)J1(GPH1) 3 1(CALC)6(g)2(Log) 4 6(DRAW) k Selecting the Regression Type After you graph paired-variable statistical data, you can use the function menu at the bottom of the display to select from a variety of different types of regression. • {ax+b}/{a+bx}/{Med}/{X^2}/{X^3}/{X^4}/{Log}/{ae^bx}/{ab^x}/{Pwr}/{Sin}/{Lgst} ... {linear regression (ax+b form)}/{linear regression (a+bx form)}/{Med-Med}/{quadratic regression}/{cubic regression}/{quartic regression}/{logarithmic regression}/{exponential regression (aebx form)}/{exponential regression (abx form)}/{power regression}/ {sinusoidal regression}/{logistic regression} calculation and graphing • {2VAR}... {paired-variable statistical results} k Displaying Regression Calculation Results Whenever you perform a regression calculation, the regression formula parameter (such as a and b in the linear regression y = ax + b) calculation results appear on the display. You can use these to obtain statistical calculation results. Regression parameters are calculated as soon as you press a function key to select a regression type, while a graph is on the display. The following parameters are used by linear regression, logarithmic regression, exponential regression, and power regression. r .............. correlation coefficient r2 ............. coefficient of determination MSe......... mean square error 5-10 k Graphing Statistical Calculation Results While the parameter calculation result is on the display, you can graph the displayed regression formula by pressing 6(DRAW). k Linear Regression Graph Linear regression uses the method of least squares to plot a straight line that passes close to as many data points as possible, and returns values for the slope and y-intercept (y-coordinate when x = 0) of the line. The graphic representation of this relationship is a linear regression graph. 1(CALC)2(X) 1(ax+b) or 2(a+bx) 6(DRAW) The following is the linear regression model formula. y = ax + b a ............. regression coefficient (slope) b ............. regression constant term (y-intercept) y = a + bx a ............. regression constant term (y-intercept) b ............. regression coefficient (slope) k Med-Med Graph When it is suspected that there are a number of extreme values, a Med-Med graph can be used in place of the least squares method. This is similar to linear regression, but it minimizes the effects of extreme values. 1(CALC)3(Med) 6(DRAW) The following is the Med-Med graph model formula. y = ax + b a .............. Med-Med graph slope b .............. Med-Med graph y-intercept k Quadratic/Cubic/Quartic Regression Graph A quadratic/cubic/quartic regression graph represents connection of the data points of a scatter diagram. It uses the method of least squares to draw a curve that passes close to as many data points as possible. The formula that represents this is quadratic/cubic/quartic regression. Ex. Quadratic regression 1(CALC)4(X^2) 6(DRAW) 5-11 Quadratic regression Cubic regression Model formula....... y = ax + bx + c Model formula....... y = ax3 + bx2 + cx + d 2 a .......... regression second coefficient b .......... regression first coefficient c .......... regression constant term (y-intercept) a .......... regression third coefficient b .......... regression second coefficient c .......... regression first coefficient d .......... regression constant term (y-intercept) Quartic regression Model formula....... y = ax4 + bx3 + cx2 + dx + e a .......... regression fourth coefficient b .......... regression third coefficient c .......... regression second coefficient d .......... regression first coefficient e .......... regression constant term (y-intercept) k Logarithmic Regression Graph Logarithmic regression expresses y as a logarithmic function of x. The standard logarithmic regression formula is y = a + b × In x, so if we say that X = In x, the formula corresponds to linear regression formula y = a + bX. 1(CALC)6(g)2(Log) 6(DRAW) The following is the logarithmic regression model formula. y = a + b·ln x a .............. regression constant term b .............. regression coefficient k Exponential Regression Graph Exponential regression expresses y as a proportion of the exponential function of x. The standard exponential regression formula is y = a × ebx, so if we take the logarithms of both sides we get In y = In a + bx. Next, if we say Y = In y, and A = In a, the formula corresponds to linear regression formula Y = A + bx. 1(CALC)6(g)3(EXP) 1(aeˆbx) or 2(abˆx) 6(DRAW) The following is the exponential regression model formula. y = a·ebx a .............. regression coefficient b .............. regression constant term y = a· bx a .............. regression constant term b .............. regression coefficient 5-12 k Power Regression Graph Power regression expresses y as a proportion of the power of x. The standard power regression formula is y = a × xb, so if we take the logarithm of both sides we get In y = In a + b × In x. Next, if we say X = In x, Y = In y, and A = In a, the formula corresponds to linear regression formula Y = A + bX. 1(CALC)6(g)4(Pwr) 6(DRAW) The following is the power regression model formula. y = a·xb a .............. regression coefficient b .............. regression power k Sinusoidal Regression Graph Sinusoidal regression is best applied for cyclical data. The following is the sinusoidal regression model formula. y = a·sin(bx + c) + d 1(CALC)6(g)5(Sin) 6(DRAW) Drawing a sine regression graph causes the angle unit setting of the calculator to automatically change to Rad (radians). The angle unit does not change when you perform a sine regression calculation without drawing a graph. • Certain types of data may take a long time to calculate. This does not indicate malfunction. k Logistic Regression Graph Logistic regression is best applied for time-based phenomena in which there is a continual increase until a saturation point is reached. The following is the logistic regression model formula. y= c 1 + ae–bx 1(CALC)6(g)6(g)1(Lgst) 6(DRAW) • Certain types of data may take a long time to calculate. This does not indicate malfunction. k Residual Calculation Actual plot points (y-coordinates) and regression model distance can be calculated during regression calculations. 5-13 While the statistical data list is on the display, recall the Setup screen to specify a LIST (“List 1” through “List 26”) for “Resid List”. Calculated residual data is stored in the specified list. The vertical distance from the plots to the regression model will be stored in the list. Plots that are higher than the regression model are positive, while those that are lower are negative. Residual calculation can be performed and saved for all regression models. Any data already existing in the selected list is cleared. The residual of each plot is stored in the same precedence as the data used as the model. k Displaying the Calculation Results of a Drawn Paired-Variable Graph Paired-variable statistics can be expressed as both graphs and parameter values. When these graphs are displayed, the paired-variable calculation results appear as shown below when you press 1(CALC)1(2VAR). • Use c to scroll the list so you can view the items that run off the bottom of the screen. o ........... mean of data stored in xList Σy2 ........ sum of squares of data stored in yList Σx ......... sum of data stored in xList σy .......... population standard deviation of data stored in yList Σx2 ........ sum of squares of data stored in xList σx .......... population standard deviation of data stored in xList sy .......... sample standard deviation of data stored in yList Σxy ........ sum of the product of data stored in xList and yList sx .......... sample standard deviation of data stored in xList minX ...... minimum of data stored in xList n ........... number of data maxX ..... maximum of data stored in xList p ............ mean of data stored in yList minY ...... minimum of data stored in yList Σy ......... sum of data stored in yList maxY ..... maximum of data stored in yList 4.

Press 1(YES) to delete the selected program or 6(NO) to abort the operation without deleting anything. u Program and Text File Conversion Rules Conversion of program and text files is subject to the following rules. • Certain characters in the program name are automatically replaced and the result is assigned as the file name whenever you convert a program to a text file. When you convert from a text file to a program, the program name is assigned by converting in the opposite direction. Program Name Characters Text File Name Characters r _r_ _t_ _s_ _q_ _p_ _x_ _d_ _+_ _-_ Ƨ Leading/trailing spaces " Leading/trailing dots × ÷ + − • The following header information is added to the text file when converting from a program to a text file. 'Program Mode: RUN (RUN Mode program) 'Program Mode: BASE (BASE Mode program) • Converting a text file that contains the above header information to a program converts to a program of the mode specified in the header information. The header information line text is not included in the converted program. • Converting a program to a text file causes all CASIO scientific function calculator-specific commands in the program to be replaced by special corresponding character strings. Conversely, converting from a text file to a program converts the special character strings back to their corresponding commands. For information about program commands and their corresponding special character strings, see “CASIO Scientific Function Calculator Special Commands ⇔ Text Conversion Table” (page 6-34). 6-7 u To convert a program to a text file 1. In the program list, use f and c to move the highlighting to the name of the program you want to convert to a text file. 2. Press 6(g)3(SV • AS). • This starts conversion to a text file. The message “Complete!” appears after conversion is complete. To close the message dialog box, press J. • The resulting text file is stored in the storage memory’s @MainMem\PROGRAM folder, under a name that is basically the same as the original file, except for certain special characters. For details about special character exceptions, see “Program and Text File Conversion Rules” above. Important! A program that is password protected cannot be converted to a text file. To convert a password protected file, first use the procedure under “To remove password protection from a program” (page 6-9) to remove password protection and then convert it. u Auto Conversion from Text Files to Programs Whenever you terminate the USB connection between the calculator and computer, all of the text files that were transferred from the computer to Storage Memory\@MainMem\PROGRAM\ while they were connected will be automatically converted to programs and stored in the calculator’s main memory. For details, see “Transferring Data between the Calculator and a Personal Computer” (page 10-3). u To convert a text file to a program Important! Using the procedure below to convert a text file to a program will create and save a program under a name that is basically the same as the original file, except for certain special characters. For details about special character exceptions, see “Program and Text File Conversion Rules” (page 6-7). If there is already a program in memory with the same name as the program created by the conversion process, the existing program will be overwritten automatically with the new program. If you do not want such an existing program to be overwritten, use the program list to change its name before performing this procedure. 1. Copy the text file to be converted to a program to the calculator’s storage memory root directory or in any folder up to three levels under the root directory. • For information about the procedure for copying files from a computer to this calculator’s storage memory, see “Chapter 10 Data Communication”. 2.

Boldface Text ............. Actual commands and other items that always must be input are shown in boldface. {Curly Brackets} ........... Curly brackets are used to enclose a number of items, one of which must be selected when using a command. Do not input the curly brackets when inputting a command. [Square Brackets] ........ Square brackets are used to enclose items that are optional. Do not input the square brackets when inputting a command. Numeric Expressions ... Numeric expressions (such as 10, 10 + 20, A) indicate constants, calculations, numeric constants, etc. Alpha Characters ......... Alpha characters indicate literal strings (such as AB). 6-10 k Basic Operation Commands " " (Text string display) Function: Causes the text string inside the quotation marks (" ") to appear on the display. Syntax: "<text string>" Example: "Test #01" Description: Enclosing alphabetic characters, numerals, calculation commands or other text inside the quotation marks (" ") causes the text to be displayed as comment text. “<text string>” can contain up to 255 bytes of text. ?→ (Value input for assignment to a variable) Function: Displays a prompt for input of a value to be assigned to a variable. Syntax 1: ?→<variable name> Syntax 2: "<text string>" ?→<variable name> Example 1: ?→A Example 2: "Input"?→A Description: • This command pauses the program and displays a prompt for input of a value to be assigned to a variable. Syntax 1 displays a question mark (?) for the prompt, while Syntax 2 displays the <text string> text followed by a question mark (?). Up to 255 bytes of text can be specified for the <text string>. • Input in response to the input command must be a value or an expression, and the expression cannot be a multi-statement. • You can specify a list name, matrix name, string memory, function memory (fn), etc. as a variable name. ? (Display of the variable’s current value and value input for assignment to a variable) Function: Displays the value currently assigned to a value and prompts for input of new value to be assigned to the variable, if desired. Syntax 1: ?<variable name> Syntax 2: "<text string>" ?<variable name> Example 1: ?A Example 2: "Input"? A Description: • This command pauses the program and displays a prompt for input of a value to be assigned to a variable on the left side of the screen. At the same time the value currently assigned to the variable is displayed on the right side of the screen. • Syntax 1 displays a question mark (?) for the prompt, while Syntax 2 displays the <text string> text followed by a question mark (?). Up to 255 bytes of text can be specified for the <text string>. • Input in response to the input command must be a value or an expression, and the expression cannot be a multi-statement. • An alphabetic character from A to Z can be specified as the variable name. 6-11 ^ (Output Command) Function: Displays an intermediate result during program execution. Description: • This command momentarily interrupts program execution and displays alpha character text or the result of the calculation immediately before the command. • The output command should be used at locations where you would normally press the w key during a manual calculation. : (Multi-statement Command) Function: Connects two statements for sequential execution without stopping. Description: • Unlike the output command (^), statements connected with the multi-statement command are executed non-stop. • The multi-statement command can be used to link two calculation expressions or two commands. • You can also use a carriage return indicated by _ in place of the multi-statement command. _ (Carriage Return) Function: Connects two statements for sequential execution without stopping. Description: • Operation of the carriage return is identical to that of the multi-statement command. • You can create a blank line in a program by inputting a carriage return only. Using a carriage return in place of the multi-statement command makes the displayed program easier to read. ’ (Comment Text Delimiter) Function: Indicates comment text inserted inside a program. Description: Anything following the apostrophe is treated as non-executable comment text. 6-12 k Program Commands (COM) If~Then~(Else~)IfEnd Function: The Then-statement is executed only when the If-condition is true (non-zero). The Else-statement is executed when the If-condition is false (0). The IfEnd-statement is always executed following either the Then-statement or Else-statement. Syntax: If <condition> numeric expression _ : ^ _ : ^ Then <statement> Else <statement> _ : ^ <statement> _ : ^ <statement> _ : ^ IfEnd Parameters: condition, numeric expression Description: (1) If ~ Then ~ IfEnd • When the condition is true, execution proceeds with the Then-statement and then continues with the statement following IfEnd. • When the condition is false, execution jumps to the statement following IfEnd. (2) If ~ Then ~ Else ~ IfEnd • When the condition is true, execution proceeds with the Then-statement and then jumps to the statement following IfEnd. • When the condition is false, execution jumps to the Else-statement and then continues with the statement following IfEnd. For~To~(Step~)Next Function: This command repeats everything between the For-statement and the Nextstatement. The starting value is assigned to the control variable with the first execution, and the value of the control variable is changed according to the step value with each execution. Execution continues until the value of the control variable exceeds the ending value. Syntax: For <starting value> → <control variable name> To <ending value> Step <step value> _ : ^ Next Parameters: • control variable name: A to Z • starting value: value or expression that produces a value (i.e. sin x, A, etc.) • ending value: value or expression that produces a value (i.e. sin x, A, etc.) • step value: numeric value (default: 1) Description: • The default step value is 1. • Making the starting value less than the ending value and specifying a positive step value causes the control variable to be incremented with each execution. Making the starting value greater than the ending value and specifying a negative step value causes the control variable to be decremented with each execution. 6-13 Do~LpWhile Function: This command repeats specific commands as long as its condition is true (nonzero). Syntax: Do _ : ^ <statement> _ : ^ LpWhile <condition> numeric expression Parameters: expression Description: • This command repeats the commands contained in the loop as long as its condition is true (non-zero). When the condition becomes false (0), execution proceeds from the statement following the LpWhile-statement. • Since the condition comes after the LpWhile-statement, the condition is tested (checked) after all of the commands inside the loop are executed. While~WhileEnd Function: This command repeats specific commands as long as its condition is true (nonzero). Syntax: While <condition> numeric expression _ : ^ <statement> _ : ^ WhileEnd Parameters: expression Description: • This command repeats the commands contained in the loop as long as its condition is true (non-zero). When the condition becomes false (0), execution proceeds from the statement following the WhileEnd-statement. • Since the condition comes after the While-statement, the condition is tested (checked) before the commands inside the loop are executed. k Program Control Commands (CTL) Break Function: This command breaks execution of a loop and continues from the next command following the loop. Syntax: Break_ Description: • This command breaks execution of a loop and continues from the next command following the loop. • This command can be used to break execution of a For-statement, Do-statement, and Whilestatement. 6-14 Prog Function: This command specifies execution of another program as a subroutine. In the RUN • MAT mode, this command executes a new program. Syntax: Prog "file name"_ Example: Prog "ABC"_ Description: • Even when this command is located inside of a loop, its execution immediately breaks the loop and launches the subroutine. • This command can be used as many times as necessary inside of a main routine to call up independent subroutines to perform specific tasks. • A subroutine can be used in multiple locations in the same main routine, or it can be called up by any number of main routines. Main Routine A Subroutines D Prog "D" Prog "C" C E Prog "E" Prog "I" Level 1 Level 2 I J Prog "J" Level 3 Level 4 • Calling up a subroutine causes it to be executed from the beginning. After execution of the subroutine is complete, execution returns to the main routine, continuing from the statement following the Prog command. • A Goto~Lbl command inside of a subroutine is valid inside of that subroutine only. It cannot be used to jump to a label outside of the subroutine. • If a subroutine with the file name specified by the Prog command does not exist, an error occurs. • In the RUN • MAT mode, inputting the Prog command and pressing w launches the program specified by the command. Return Function: This command returns from a subroutine. Syntax: Return_ Description: Execution of the Return command inside a main routine causes execution of the program to stop. Execution of the Return command within a subroutine terminates the subroutine and returns to the program from which the subroutine was jumped to. Stop Function: This command terminates execution of a program. Syntax: Stop_ Description: • This command terminates program execution. • Execution of this command inside of a loop terminates program execution without an error being generated. 6-15 k Jump Commands (JUMP) Dsz Function: This command is a count jump that decrements the value of a control variable by 1, and then jumps if the current value of the variable is zero. Syntax: Variable Value ≠ 0 _ Dsz <variable name> : <statement> : ^ Variable Value = 0 <statement> Parameters: variable name: A to Z, r, θ [Example] Dsz B : Decrements the value assigned to variable B by 1. Description: This command decrements the value of a control variable by 1, and then tests (checks) it. If the current value is non-zero, execution continues with the next statement. If the current value is zero, execution jumps to the statement following the multi-statement command (:), display command (^), or carriage return (_). Goto~Lbl Function: This command performs an unconditional jump to a specified location. Syntax: Goto <label name> ~ Lbl <label name> Parameters: label name: value (0 to 9), variable (A to Z, r, θ) Description: • This command consists of two parts: Goto n (where n is a parameter as described above) and Lbl n (where n is the parameter referenced by Goto n). This command causes program execution to jump to the Lbl-statement whose n parameter matches that specified by the Goto-statement. • This command can be used to loop back to the beginning of a program or to jump to any location within the program. • This command can be used in combination with conditional jumps and count jumps. • If there is no Lbl-statement whose value matches that specified by the Goto-statement, an error occurs. Isz Function: This command is a count jump that increments the value of a control variable by 1, and then jumps if the current value of the variable is zero. Syntax: Variable Value ≠ 0 _ Isz <variable name> : <statement> : ^ Variable Value = 0 <statement> Parameters: variable name: A to Z, r, θ [Example] Isz A : Increments the value assigned to variable A by 1. 6-16 Description: This command increments the value of a control variable by 1, and then tests (checks) it. If the current value is non-zero, execution continues with the next statement. If the current value is zero, execution jumps to the statement following the multi-statement command (:), display command (^), or carriage return (_). ⇒ (Jump Code) Function: This code is used to set up conditions for a conditional jump. The jump is executed whenever the conditions are false. Syntax: True _ <left side> <relational operator> <right side> ⇒ <statement> : ^ False <statement> Parameters: • left side/right side: variable (A to Z, r, θ), numeric constant, variable expression (such as: A × 2) • relational operator: =, ≠, >, <, ≥, ≤ (page 6-20) Description: • The conditional jump compares the contents of two variables or the results of two expressions, and a decision is made whether or not to execute the jump based on the results of the comparison. • If the comparison returns a true result, execution continues with the statement following the ⇒ command. If the comparison returns a false result, execution jumps to the statements following the multi-statement command (:), display command (^), or carriage return (_). Menu Function: Creates a branching menu in a program. Syntax: Menu "<string (menu name)>", "<string (branch name) 1>", <value or variable 1>, "<string (branch name) 2>" ,<value or variable 2>, ... , "<string (branch name) n>", <value or variable n> Parameters: value (0 to 9), variable (A to Z, r, θ) Description: • Each "<string (branch name) n>" ,<value or variable n> part is a branch set, and the entire branch set must be included. • From two to nine branching sets can be included. An error occurs when there is only one or more than nine branching sets. • Selecting a branch on the menu while the program is running jumps to the same type of label (Lbl n) as the one used in combination with the Goto command. Specifying “"OK", 3” for the “"<string (branch name) n>", <value or variable n>” part specifies a jump to Lbl 3. Example: Lbl 2_ Menu "IS IT DONE?", "OK", 1, "EXIT", 2_ Lbl 1_ "IT’S DONE !" 6-17 k Clear Commands (CLR) ClrGraph Function: This command clears the graph screen. Syntax: ClrGraph_ Description: This command clears the graph screen during program execution. ClrList Function: This command deletes list data. Syntax: ClrList <list name> ClrList Parameters: list name: 1 to 26, Ans Description: This command deletes the data in the list specified by “list name”. All list data is deleted if nothing is specified for “list name”. ClrMat Function: This command deletes matrix data. Syntax: ClrMat <matrix name> ClrMat Parameters: matrix name: A to Z, Ans Description: This command deletes the data in the matrix specified by “matrix name”. All matrix data is deleted if nothing is specified for “matrix name”. ClrText Function: This command clears the text screen. Syntax: ClrText_ Description: This command clears text from the screen during program execution. k Display Commands (DISP) DrawStat Function: This draws a statistical graph. Syntax: See “Using Statistical Calculations and Graphs in a Program” on page 6-28. Description: This command draws a statistical graph in accordance with conditions defined within the program. 6-18 k Input/Output Commands (I/O) Getkey Function: This command returns the code that corresponds to the last key pressed. Syntax: Getkey_ Description: • This command returns the code that corresponds to the last key pressed. 79 69 78 68 77 67 34 39 29 28 38 59 49 58 27 37 48 57 33 32 64 24 54 44 73 63 23 53 43 74 62 22 52 42 72 61 21 71 41 31 • A value of zero is returned if no key was pressed previous to executing this command. • This command can be used inside of a loop. Locate Function: This command displays alpha-numeric characters at a specific location on the text screen. Syntax: Locate <column number>, <line number>, <value> Locate <column number>, <line number>, <numeric expression> Locate <column number>, <line number>, "<string>" [Example] Locate 1, 1, "AB"_ Parameters: • line number: number from 1 to 7 • column number: number from 1 to 21 • value and numeric expression • string: character string 6-19 Description: • This command displays values (including variable contents) or text at a specific location on the text screen. If there is a calculation input, that calculation result is displayed. • The line is designated by a value from 1 to 7, while the column is designated by a value from 1 to 21. (1, 1) → ← (21, 1) (1, 7) → ← (21, 7) Example: Cls_ Locate 7, 1, "CASIO FX" This program displays the text “CASIO FX” in the center of the screen. • In some cases, the ClrText command should be executed before running the above program. k Conditional Jump Relational Operators (REL) =, ≠, >, <, ≥, ≤ Function: These relational operators are used in combination with the conditional jump command. Syntax: <left side> <relational operator> <right side> Parameters: • left side/right side: variable (A to Z, r, θ), numeric constant, variable expression (such as: A × 2) • relational operator: =, ≠, >, <, ≥, ≤ k Strings A string is a series of characters enclosed in double quotes. In a program, strings are used to specify display text. A string made up of numbers (like "123") or an expression (like "x–1") cannot be processed as a calculation. To display a string at a specific location on the screen, use the Locate command (page 6-19). • To include double quotes (") or a backslash (\) in a string, put a backslash (\) in front of the double quotes (") or backslash (\). Example 1: To include Japan: “Tokyo” in a string "Japan:\"Tokyo\"" Example 2: To include main\abc in a string "main\\abc" You can input a backslash from the menu that appears when you press 6(CHAR)2(SYBL) in the PRGM mode, or from the String category of the catalog that appears when you press !a(CATALOG). • You can assign strings to string memory (Str 1 through Str 20). For details about strings, see “String Memory” (page 3-5). 6-20 • You can use the “+” command (page 6-22) to connect strings inside of an argument. • A function or command within a string function (Exp(, StrCmp(, etc.) is treated as a single character. For example, the “sin” function is treated as a single character. Exp( Function: Converts a string to an expression, and executes the expression. Syntax: Exp("<string>"[)] Exp'Str( Function: Converts an expression to a string and assigns it to the specified variable. Syntax: Exp'Str(<formula>, <string variable name>[)] Description: Function memory (fn) can be used as the first argument (<formula>). StrCmp( Function: Compares “<string 1>” and “<string 2>” (character code comparison). Syntax: StrCmp("<string 1>", "<string 2>"[)] Description: Compares two strings and returns one of the following values. Returns 0 when “<string 1>” = “<string 2>”. Returns 1 when “<string 1>” > “<string 2>”. Returns –1 when “<string 1>” < “<string 2>”. Strlnv( Function: Inverts the sequence of a string. Syntax: StrInv("<string>"[)] StrJoin( Function: Joins “<string 1>” and “<string 2>”. Syntax: StrJoin("<string 1>", "<string 2>"[)] Note: The same result also can be achieved using the “+” command (page 6-22). StrLeft( Function: Copies a string up to the nth character from the left. Syntax: StrLeft("<string>", n[)] (0 < n < 9999, n is a natural number) StrLen( Function: Returns the length of a string (the number of its characters). Syntax: StrLen("<string>"[)] StrLwr( Function: Converts all the characters of a string to lower case. Syntax: StrLwr("<string>"[)] 6-21 StrMid( Function: Extracts from the n-th to the m-th character of a string. Syntax: StrMid("<string>", n [,m)] (0 < n < 9999, n is a natural number) Description: Omitting “m” will extract from the n-th character to the end of the string. StrRight( Function: Copies a string up to the nth character from the right. Syntax: StrRight("<string>", n[)] (0 < n < 9999, n is a natural number) StrRotate( Function: Rotates the left side part and right side part of a string at the nth character. Syntax: StrRotate("<string>", [,n)] (–9999 < n < 9999, n is an integer) Description: Rotation is to the left when “n” is positive, and to the right when “n” is negative. Omitting “n” uses a default value of +1. Example: StrRotate("abcde", 2) ........ Returns the string “cdeab”. StrShift( Function: Shifts a string left or right n characters. Syntax: StrShift("<string>", [,n)] (–9999 < n < 9999, n is an integer) Description: Shift is to the left when “n” is positive, and to the right when “n” is negative. Omitting “n” uses a default value of +1. Example: StrShift("abcde", 2) ........ Returns the string “cde”. StrSrc( Function: Searches “<string 1>” starting from the specified point (nth character from beginning of string) to determine if it contains the data specified by “<string 2>”. If the data is found, this command returns the location of the first character of “<string 2>”, starting from the beginning of “<string 1>”. Syntax: StrSrc("<string 1>", "<string 2>"[,n)] (0 < n < 9999, n is a natural number) Description: Omitting the start point causes the search to start from the beginning of “<string 1>”. StrUpr( Function: Converts all the characters of a string to upper case. Syntax: StrUpr("<string>"[)] + Function: Joins “<string 1>” and “<string 2>”. Syntax: "<string 1>"+"<string 2>" Example: "abc"+"de"→Str 1 .......... Assigns “abcde” to Str 1. 6-22 k CSV Access Commands CSV access commands provide a means to directly load data into a program from a CSV file in storage memory or on an SD card. • For sake of simplicity, the explanations in this section use numbers (1, 2, 3, etc.) for rows and letters (A, B, C, etc.) for columns. For example, the cell in the upper left corner of any CSV file (the first cell in the file) is Cell A1. The cell in the lower right corner of a 3 × 3 CSV file would be Cell C3. • The term “next cell” is used to refer to the cell immediately to the right of the current cell. If the current cell is at the end of a row (the rightmost cell), the “next cell” is the first (leftmost) cell in the row below it. The table below shows the six CSV access codes. Command Overview CSVInfo Gets the row count and column count of a CSV file and outputs the result in list format. OpenCSV Opens a CSV file. CloseCSV Closes the currently open CSV file. LoadNextCell Loading of CSV file data with CSV access commands is always performed in cell units. The first execution of the LoadNextCell command following the OpenCSV command makes the first cell of the file the load target cell. After that, each subsequent execution will sequentially switch the load target cell to the next cell. Each execution of this command gets the attribute data of the load target cell and outputs it in list format. GetCellValue Gets the data in the current load target cell and outputs it as a value. GetCellString Gets the data in the current load target cell and outputs it as a text string. The rough flow for a program would be as shown below. OpenCSV: To open the CSV file LoadNextCell: To specify the load target cell GetCellValue; GetCellString: To get the cell data CloseCSV: To close the CSV file CSV File Handling Precautions Note the following precautions whenever handling CSV files with CSV access commands. • Specification of a comma (,) or semicolon (;) as the delimiter symbol, and a period (.) or comma (,) as the decimal point symbol is in accordance with the calculator’s “CSV Separator” and “CSV Decimal Symbol” setting. For details, refer to “Specifying the CSV File Delimiter Symbol and Decimal Point” (page 4-15). • CR, LF, and CRLF in a CSV file are all recognized as line feed codes. • Single spaces and tab operations at the beginning of rows, before or after delimiter symbols, and before line feeds, and multiple spaces and tabs in a CSV file are ignored. 6-23 • Anything in a CSV file between a pair of quotation marks (" "), between quotation marks (") and a line feed, or between quotation marks (") and the end of a file is treated as a text string. Any delimiter symbol within a text string range is ignored. CSVInfo Function: Gets the row count and column count of the CSV file specified by the path and file name and outputs the result in list format. Syntax: CSVInfo "<path>\\<filename>" Example: CSVInfo "SMEM:\\Data0827.csv"→List 1 The above gets the row count and column count of the file named "Data0827.csv", which is located in the storage memory root directory, and outputs the result to List 1 in the format {row count, column count}. CSVInfo "SD:\\FOLDER1\\Data0827.csv"→List 1 The above gets the row count and column count of the file named "Data0827.csv", which is located in FOLDER1 of the SD card, and outputs the result to List 1 in the format {row count, column count}. Description: • If the CSV file contains rows of different lengths (different number of columns), the number of columns value produced by this command will be for the longest line. • This command cannot be used to access a CSV file that is currently open with the OpenCSV command. OpenCSV Function: Opens the CSV file specified by the path and file name (including extension). Syntax: OpenCSV "<path>\\<filename>" Example: OpenCSV "SMEM:\\Data0827.csv" OpenCSV "SD:\\FOLDER1\\Data0827.csv" Description: • A CSV file must be opened with this command in order to load data from the file. • A file with a file name extension other than .csv (such as .txt) can be specified with this command as long as it is a text file that includes delimiter symbols and line feed codes. • Opening multiple instances of the same file and opening multiple CSV files at the same time are not supported. To re-open the currently opened CSV file, first be sure to execute the CloseCSV command then execute the OpenCSV command. CloseCSV Function: Closes the currently open CSV file. Syntax: CloseCSV Description: This command is used in combination with the OpenCSV command. The currently open CSV file is forced to close automatically when a program ends, even if CloseCSV is not executed. 6-24 LoadNextCell Function: Switches the load target cell of the CSV file to the next cell, and outputs attribute information of the new load target cell in list format. Syntax: LoadNextCell Example: LoadNextCell→List 20 Description: • After opening a CSV file with OpenCSV, this command must be executed once before using GetCellValue or GetCellString to get data from a file. Executing this command after opening a CSV file uses the first cell in the file as the data load target. After that, each executing shift the load focus to the next cell. • Each execution of this command outputs the attributes of the load target cell in the following list format {status, row number, column number}. Status is assigned one of the integers described below. 0: Null data; 1: Value; 2: Text string (non-value data); −1: File end −1 (file end) is returned when LoadNextCell is executed while the load target cell is last cell (in a 3×3 CSF file, for example, Cell C3) in the CSF file. Executing LoadNextCell again after file end is returned results in an error (Range ERROR). GetCellValue Function: Gets the data in the load target cell in the CSV file and outputs it as a value. Syntax: GetCellValue Example: GetCellValue→List 1[N] The above gets the data of the load target cell and assigns the value to the nth element in List 1. Description: Executing this command when the data of the load target cell is not value data or null data results in an error (Data ERROR). GetCellString Function: Gets the data in the load target cell in the CSV file and outputs it as a text string. Syntax: GetCellString Example: GetCellString→Str 1 The above gets the data of the load target cell and assigns it to Str1 as a text string. Description: Executing this command when the data of the load target cell is value data does not result in an error. 6-25 6. Using Calculator Functions in Programs k Text Display You can include text in a program by simply enclosing it between double quotation marks.

CASIO Scientific Function Calculator Special Commands ⇔ Text Conversion Table The table below shows the special text strings that correspond to commands when converting between programs and text files. For details about the operations for converting between programs and text files, see “Converting Programs and Text Files” (page 6-7). Important! • Converting a program that contains the types of commands described below to a text file will cause the commands to be converted to text strings with underbar (_) characters appended at the beginning and end, as shown in the table below. - A command enclosed in quotation marks (" ") - A command in a comment line, which is a line that begins with a single quotation mark (') Note that non-command alpha-numeric characters in a program that are enclosed in quotation marks (" ") or are in a comment line are output to the text file as-is. Example: In the program: "Ƨ " "Theta"*1 "or"*2 "or"*1 In the text file (after conversion): ˝ _Theta_ ˝ ˝ Theta ˝ ˝ _or_ ˝ ˝ or ˝ *1 Non-command alpha-numeric characters *2 Logical operator or Converting from a text file to a program converts the special character strings back to their corresponding commands, shown above. • When converting a program that contains special characters input using 6(CHAR) when editing the program on the calculator, the special characters will be converted to character string codes as shown below. Example: In the program: Λ ơ ` ⇔ In the text file (after conversion): #E54A #E5A5 #E641 #E69C #E6D6 These codes are not included in the tables on the pages 6-35 through 6-38. 6-34 * “ ” in the following tables indicates a space.

Spreadsheet Basics and the Function Menu Selecting S • SHT on the Main Menu will display a spreadsheet screen. Entering the S • SHT mode automatically creates a new spreadsheet file named “SHEET”. The spreadsheet screen shows a number of cells (squares) and the data contained in each cell. File name Shows as many characters as possible of the ﬁle name. Column letters (A to Z) Cell cursor Row numbers (1 to 999) Edit box Shows the contents of the cell where the cell cursor is currently located. When multiple cells are selected, the edit box indicates the selected cell range. Function menu You can enter the following types of data into a cell. Constants A constant is something whose value is fixed as soon as you finalize its input. A constant can be either a numeric value, or a calculation formula (such as 7+3, sin30, A1×2, etc.) that does not have an equal sign (=) in front of it. Text A character string that starts with a quote mark (") is treated as text. Formula A formula that starts out with an equal sign (=), such as =A1×2, is executed as it is written. Note that complex numbers are not supported in the S • SHT mode. k Spreadsheet Screen Function Menu • {FILE} ...

On the dialog box that appears, enter up to eight characters for the file name, and then press w. • This will create a new file and display a blank spreadsheet. • A new file will not be created it there is already a file with the same file name you enter in step 2. Instead, the existing file will be opened. u To open a file 1. Press 1(FILE)2(OPEN). 2. On the file list that appears, use f and c to select the file you want and then press w. u Auto Save In the S • SHT mode, Auto Save saves the currently open file automatically whenever you edit it. This means you do not need to perform any manual save operation. 7-2 u To save a file under a new name 1. Press 1(FILE)3(SV • AS). 2. On the dialog box that appears, enter up to eight characters for the new file name, and then press w. • If a file already exists with the same file name you enter in step 2, a message will appear asking if you want to replace the existing file with the new one. Press 1(Yes) to replace the existing file, or 6(No) to cancel the save operation and return to the file name input dialog box in step 2. u To delete a file 1. Press 1(FILE)2(OPEN). 2. On the file list that appears, use f and c to select the file you want to delete and then press 1(DEL). 3. This causes a confirmation message to appear. Press 1(Yes) to delete the file, or 6(No) to cancel without deleting anything. 4. To return to the spreadsheet from the file list, press J. • Deleting all of the files will automatically create a new file named “SHEET” and display its spreadsheet. k Transferring Data between a Spreadsheet and CSV Files You can import the contents of a CSV file stored with this calculator or transferred from a computer into a spreadsheet. You also can save the contents of a spreadsheet as a CSV file. u To import the contents of a CSV file to a spreadsheet 1. Prepare the CSV file you want to import. • See “Import CSV File Requirements” (page 4-13). 2. Press 1(FILE)5(CSV)1(LOAD). • This will display a dialog box for specifying whether a CSV file should be imported from storage memory or the SD card. 3. Select b(Storage Mem) to select storage memory, or c(SD Card) to select the SD card. • Pressing w in the next step will overwrite all of the data on the spreadsheet with the CSV file data. 4. On the select file dialog box that appears, use f and c to move the highlighting to the file you want to import and then press w. • This imports the contents of the CSV file you specified to the spreadsheet. Important! • All blank data in the CSV file is imported as a blank cell. • An error occurs if a CSV file contains even a single text string data item. • If the CSV file includes data that cannot be converted, an error message will appear showing the location in the CSV file (Example: row 2, column 3) where the data that cannot be converted is located. • Attempting to import a CSV file that has more than 26 columns or 999 rows will cause an “Invalid Data Size” error. 7-3 u To save spreadsheet contents as a CSV file 1. If required, press 1(FILE)4(RECAL) to recalculate the spreadsheet contents. • Note that recalculation is not performed automatically when you save spreadsheet contents to a CSV file. Be sure to perform recalculation if the spreadsheet contains a formula, which starts with an equals symbol (=). See “Inputting a Formula into a Cell” (page 7-9) for more information. • Formulas are not saved to the CSV file. Only calculation results are saved. • All ERROR cell data on the spreadsheet is saved as blank data. 2. Press 1(FILE)5(CSV)2(SV • AS). • This will display a dialog box for specifying whether the CSV file should be saved to storage memory or the SD card. 3. Select b(Storage Mem) to select storage memory, or c(SD Card) to select the SD card. • This displays a folder selection screen. 4. Select the folder where you want to save the CSV file. • To store the CSV file in the root directory, highlight “ROOT”. • To store the CSV file in a folder, use f and c to move the highlighting to the desired folder and then press 1(OPEN). 5. Press 1(SV • AS). 6. Input up to eight characters for the file name and then press w. • For information about how certain types of data is converted when being saved to a CSV file, see the “Important!” note under “To save matrix contents as a CSV file” (page 3-40). u To specify the CSV file delimiter symbol and decimal point Press 1(FILE)5(CSV)3(SET) to display the CSV format setting screen. Next, perform the procedure from step 3 under “Specifying the CSV File Delimiter Symbol and Decimal Point” (page 4-15). k Recalculating All of the Formulas in the Currently Open Spreadsheet The S • SHT mode has an Auto Calc features that automatically recalculates all of the formulas in a spreadsheet whenever you open it or perform any editing operation. Auto Calc is enabled under initial factory default settings. You also can execute a recalculation manually, if you want. u Auto Calc Auto Calc is an S • SHT mode Setup item (page 2-15). When Auto Calc is enabled (On), all of the formulas in a spreadsheet are recalculated when the spreadsheet is opened or when any editing operation is performed. It should be noted, however, that recalculation can slow down the overall processing speed. When Auto Calc is disabled (Off), you need to execute recalculation manually as required. u To execute spreadsheet re-calculation manually Press 1(FILE)4(RECAL). This recalculates all of the formulas in the currently open file and displays the applicable results. 7-4 k Using the Cell Cursor The cell cursor shows the cell that is selected on a spreadsheet. The highlighted cell is the one that is currently selected by the cell cursor. Cell cursor Edit box When a single cell is selected by the cell cursor, the contents of that cell are displayed in the edit box. The cell contents can be edited in the edit box. When a multiple cells are selected by the cell cursor, the selection range is displayed in the edit box. In this case, you can copy, delete, or perform other cell operations on the entire range of selected cells. u To select cells To select this: Do this: A single cell Use the cursor keys to move the cell cursor to the cell you want, or use the JUMP comment to jump directly to the cell. A range of cells See “To select a range of cells” (page 7-6). An entire row of cells Move the cell cursor to column A of the row whose cells you want to select and then press d. Pressing d while the cell cursor is located at cell A2, for example, will select the entire second row (from A2 to Z2). This will cause A2:Z2 (which indicates the selected range) to appear in the edit box. An entire column of cells. Move the cell cursor to row 1 of the column whose cells you want to select and then press f. Pressing f while the cell cursor is located at cell C1, for example, will select the entire column C (from C1 to C999). This will cause C1:C999 (which indicates the selected range) to appear in the edit box. All of the cells in the spreadsheet Press d while the entire column A is selected or press f while the entire row 1 is selected. This will select all of the cells in the spreadsheet and display the spreadsheet file name in the edit box. 7-5 u Using the JUMP Command to Move the Cell Cursor To move the cell cursor to here: Do this: A particular cell 1. Press 2(EDIT)4(JUMP)1(GO). 2. On the dialog box that appears, enter the name of the cell (A1 to Z999) to which you want to jump. 3. Press w. Line 1 of the current column Press 2(EDIT)4(JUMP)2(TOP↑). Column A of the current row Press 2(EDIT)4(JUMP)3(TOP←). Last line of the current column Press 2(EDIT)4(JUMP)4(BOT↓). Column Z of the current row Press 2(EDIT)4(JUMP)5(BOT→). u To select a range of cells 1. Move the cell cursor to the start point of the range of cells you want to select. • You could select and entire row or column of cells as the start point, if you want. For details about selecting cells, see “To select cells” on page 7-5. 2. Press !b(CLIP). • This will change the cell cursor to a thick-line boundary instead of the normal highlighting. 3. Use the cursor keys to move the cell cursor to the end point of the range of cells you want to select. • The edit box will show the range of the selected cells. • To cancel cell selection, press J. If you do, the cell cursor will be located at the end point of the range you selected. k Data (Constants, Text, Formula) Input Basics First let’s have a look at a few basic procedures that apply regardless of the type of data you are inputting. u To overwrite data currently in a cell with new data 1. Move the cell cursor to the cell where you want to input data. • If the cell you select already contains data, the following step will overwrite the existing data with new input. 2. Use the calculator’s keys to input data. • As you perform key operations to input values or text (such as b, a1(A-E)2(B), etc.), the applicable figures will appear aligned left inside the edit box. • To cancel an input operation part way through at any point before advancing to step 3 below, press J. This will return the cell contents to what they were in step 1 of this procedure. 3. To finalize and apply your input, press w. 7-6 u To edit cell data 1. Move the cell cursor to the cell whose contents you want to edit. 2. Press 2(EDIT)3(CELL). • Cell contents in the edit box will change from align left to align right. A text cursor will appear in the edit box so you can edit its contents. 3. Use e and d to move the cursor around the contents of the cell, and edit them as required. • To cancel an edit operation part way through at any point before advancing to step 4 below, press J. This will return the cell contents to what they were in step 1 of this procedure. 4. To finalize and apply your edits, press w. u To move the cell cursor while inputting data into a cell Under factory default settings, pressing w while inputting data into a cell will cause the cell cursor to move to the next line. You can specify movement to the next column instead using the “Move” setting as described on page 2-16. k Inputting a Constant (Value, Calculation Result, Number Sequence) into a Cell A constant is something whose value is fixed as soon as you finalize its input. A constant can be either a numeric value, or a calculation formula (such as 7+3, sin30, A1×2, etc.) that does not have an equal sign (=) in front of it. Inputting !h(sin)daw, for example will cause the value 0.5 (the calculation result) to appear in the cell (when Deg is selected as the Angle unit). u To input a number sequence automatically based on a function expression 1. Move the cell cursor to the cell where you want number sequence input to start. • Under initial default settings, automatic input of the number sequence will proceed downwards from the start cell. You can specify a different direction using the “Move” setting as described on page 2-16. 2. Press 2(EDIT)5(SEQ) to display the Sequence screen, and then specify the function expression and values required to generate the required number sequence. You can input data for the item that is highlighted on the screen. Reference name of the cell selected in step 1 7-7 Item Description Expr Input the function expression f(x) for generating the number sequence. Example: a5(U-Z)4(X)x+bw (X2 + 1) Var Input the variable name used in the function expression input for Expr. Example: a5(U-Z)4(X)w (X) Start Input the starting value (X1) of the value to be substituted for the variable specified by Var. Example: cw End Input the ending value (Xn) of the value to be substituted for the variable specified by Var. Example: baw Incre Input the increment value (m) for successive value of X1, as in: (X2 = X1 + m), (X3 = X2 + m), and so on. The number sequence is generated in the range of X1 + (n – 1) m < Xn. Example: cw 1st Cell Input the reference name (A1, B2, etc.) of the cell where you want the first value of the number sequence to be input. Specify a cell here only if the starting cell is different from the one you specified in step 1 of this procedure. Example: a1(A-E)2(B)bw (B1) • Each time you press w after inputting data for a setting item, the highlighting will move to the next setting item. You also can use f and c to move the highlighting upwards and downwards as required. • Performing the next step will input the number string automatically starting from the specified cell. If any cell that is within the range of cells where the number sequence values will be input already contains data, the existing data will be replaced with the number sequence values. 3. After inputting data for all the setting items, press 6(EXE) or the w key to start number sequence generation and input. ⇒ k Inputting Text into a Cell To input text, make sure the first thing you input into the cell is a6(SYBL)2(”). The quote mark (") tells the calculator that what follows is text, and should be displayed as-is without calculation. The quote mark (") is not displayed as part of the text. 7-8 k Inputting a Formula into a Cell For the sake of example, let’s try making a table that contains data based on the formula <PRICE> × <QUANTITY> = <TOTAL>. To do this, we would put <PRICE> values in column A, <QUANITY> values in column B, and calculation formulas (like = A1 × B1, = A2 × B2, and so on) in column C. If the Auto Calc feature is enabled (On), the values in column C would be recalculated and updated any time we change the values in column A or B. In this example, note that we must start out the data in column C with the equal sign (=) in order to indicate it is a formula. In addition to values, arithmetic operators, and cell reference names, a formula also can contain built-in function commands (page 3-10) and special S • SHT mode commands (page 7-15). u Formula Input Example A 1 B PRICE C QUANTITY TOTAL 2 35 15 525 3 52 15 780 4 78 20 1560 Procedure 1. Input the text for line 1, and the applicable values in cells A2 through B4. 2. Move the cursor to cell C2, and input the formula for A2 × B2. a6(SYBL)5(=)J1(A-E)1(A)c*a2(B)cw 3. Copy the formula in cell C2 and copy it into cells C3 and C4. Move the cell cursor to cell C2 and then perform the following operation. 2(EDIT)2(COPY)c1(PASTE)c1(PASTE)J • For details about the copy and paste operations, see “Copying and Pasting Cell Contents” (page 7-11). k Inputting a Cell Reference Name Each cell on a spreadsheet has what is called a “reference name”, which is derived by combining its column name (A through Z) with its row name (1 through 999). A cell reference name can be used inside of a formula, which makes the value of the called cell part of the formula. See “Inputting a Formula into a Cell” above for more information. There are two methods you can use to input a cell reference name: direct input of the name and input using the GRAB command. The following illustrates how you would use each of these methods to input =A1+5 into cell B1. 7-9 u To input a cell reference name using direct input Move the cell cursor to cell B1 and then perform the following operation. a6(SYBL)5(=)J1(A-E)1(A)b+fw u To input a cell reference name using the GRAB command Move the cell cursor to cell B1 and then perform the following operation. a6(SYBL)5(=)JJ1(GRAB)d1(SET)+fw • Commands 2(GO) through 6(BOT→) on the submenu that appears when you press 1(GRAB) are identical to commands 1(GO) through 5(BOT→) of the JUMP command submenu. See “Using the JUMP Command to Move the Cell Cursor” on page 7-6 about these commands. k Relative and Absolute Cell Reference Names There are two types of cell reference names: relative and absolute. Normally, cell reference names are treated as being relative. Relative Cell Reference Names In the formula =A1+5, the cell reference name A1 indicates a relative cell reference. It is “relative” because copying the formula and pasting in a different cell will cause the cell reference name to change in accordance with the location of cell where it is pasted. If the formula =A1+5 is originally located in cell B1, for example, copying at pasting in cell C3 will result in =B3+5 in cell C3. Moving from column A to column B (one column) causes A to change to B, while moving from row 1 to row 3 changes (two rows) changes the 1 to 3. Important!: If the result of a copy and paste operation causes a relative cell reference name to change to something that is outside the range of the spreadsheet cells, the applicable column letter and/or row number will be replaced by a question mark (?), and “ERROR” will be displayed as the cell’s data. Absolute Reference Names If you want the row or the column, or both the row and the column parts of a cell reference name to remain the same to matter where you paste them, you need to create an absolute cell reference name. You do this by affixing a dollar sign ($) in front of the part of the cell reference name you want to remain unchanged. You have three options when using the dollar sign ($) to create an absolute cell reference name: absolute column with relative row ($A1), relative column with absolute row (A$1), and absolute row and column ($A$1). u To input the absolute cell reference name symbol ($) When inputting a cell reference into a spreadsheet cell, press 2($). For example, the following key operation inputs the absolute cell reference name = $B$1 a6(SYBL)5(=)JJ2($)a1(A-E)2(B)JJ2($)b 7-10 k Copying and Pasting Cell Contents You can copy the contents of one or more cells and paste them into another location. Once you perform the copy operation, you can copy the contents to multiple locations, if you want. u To copy and paste spreadsheet data 1. Select the cell(s) you want to copy. • See “To select cells” (page 7-5) for more information. 2 Press 2(EDIT)2(COPY). • This will go into paste standby for the selected data, indicated by the 1 menu item changing to (PASTE). • You can exit the paste standby at any time before you perform step 4 below by pressing J. 3. Use the cursor keys to move the cell cursor to location where you want to paste the data. • If you selected a range of cells in step 1, the cell you select with the cell cursor will be the upper left cell of the paste range. • If the location you select is within the range that you copied, performing step below will cause the exiting data to be overwritten with the pasted data. 4. Press 1(PASTE). • This will paste the copied data. • To paste the same data in other locations, repeat steps 3 and 4. 5. After you are finish pasting the data, press J to exit paste standby. k Cutting and Pasting Cell Contents You can use cut and paste to move the contents of one or more cells to another location. Cell contents (regardless of whether it includes relative or absolute cell name references) generally are unchanged by a cut and paste operation. ⇒ Cutting the formula =A1+5 in cell B1 and pasting it into cell B2. The A1 reference name is unchanged. When you are cut and paste a range cells, reference names that affect relationships within the range are changed accordingly when the range is pasted in order to maintain the correct relationship, regardless of whether they are relative or absolute reference names. ⇒ 7-11 Cutting the B1:C1 range of cells that includes the formula =B1+5 and pasting it into B2:C2. The formula pasted into C2 is changed to =B2+5 in order to maintain the relationship with the cell to the left, which was also part of the pasted range. u To cut and paste spreadsheet data 1. Select the cell(s) you want to cut. • See “To select cells” (page 7-5) for more information. 2 Press 2(EDIT)1(CUT). • This will go into paste standby for the selected data, indicated by the 1 menu item changing to (PASTE). • You can exit the paste standby at any time before you perform step 4 below by pressing J. 3. Use the cursor keys to move the cell cursor to location where you want to paste the data. • If you selected a range of cells in step 1, the cell you select with the cell cursor will be the upper left cell of the paste range. • If the location you select is within the range that you cut, performing step below will cause the exiting data to be overwritten with the pasted data. 4. Press 1(PASTE). • This will paste the data from the cell(s) you selected in step 1 and paste it into the location you selected in step 3. • Regardless of whether Auto Calc is enabled or disabled (page 7-4), pasting cut data will cause all of the formulas in the spreadsheet to be recalculated. k Inputting the Same Formula into a Range of Cells Use the Fill command when you want to input the same formula into a specified range of cells. The rules governing relative and absolute cell name references are the same as those for copy and paste. When you need to input the same formula into cells B1, B2, and B3, for example, the Fill command lets you do so by inputting the formula once, into cell B1. Note the following about how the Fill command handles cell name references in this case. When cell B1 contains this: The Fill command will do this: =A1×2 A B 1 =A1×2 2 =A2×2 3 =A3×2 =$A$2×2 A B 1 =$A$2×2 2 =$A$2×2 3 =$A$2×2 7-12 * Note that in actual practice cells B1, B2, and B3 will show the calculation results, not the formulas as shown here. u To input the same formula into a range of cells 1. Select the range of cells into which you want to input the same formula. • In this example we will assume the B1:B3 is selected. See “To select a range of cells” (page 7-6). 2 Press 2(EDIT)6(g)1(FILL). 3. On the Fill screen that appears, enter the formula you want to input. You can input data for the item that is highlighted on the screen. This is the range of cells you selected in step 1. • In the “Formula” line, input =A1×2 (a6(SYBL)5(=)J1(A-E)1(A)b*cw). Pressing w will cause the cell cursor to move to the “Cell Range” line. • If any cell within the cell range already contains data, performing the next step will cause the existing data to be overwritten with the new fill data (formula). 4. Press 6(EXE) or the w key. • This will input the formula into the range of cells you specified. k Sorting Constant Data Note that only constant data can be sorted. You can select multiple columns within a single line or multiple lines within a single column for sorting. u To sort constant data 1. Select a range of column cells in a single row or a range of row cells in a single column. • See “To select a range of cells” (page 7-6). • A Syntax ERROR message will appear if any of the cells in the range you select contain data other than constant data. 2. Depending on the type of sort you want to perform, perform either one of the following operations. To sort ascending: 2(EDIT)6(g)2(SRT • A) To sort descending: 2(EDIT)6(g)3(SRT • D) k Deleting and Inserting Cells u To delete an entire line or column of cells Select the row(s) or column(s) you want to delete and then press 3(DEL). This will delete the selected row(s) or column(s) immediately, without displaying a confirmation message. You also can perform the following steps to delete a row or column. 7-13 1. Select one or more cells inside the row(s) or column(s) you want to delete. • If you want to delete lines 2 through 4, for example, you could select A2:B4, C2:C4, or any other range of cells that includes the lines to be deleted. • If you want to delete columns A and B, for example, you could select A1:B1, A2:B4, etc. 2. Press 3(DEL). • This enters delete standby. If you decide you want to cancel the delete operation at this time, press J. 3. To delete the entire line(s) that include the cells you selected in step 1, press 1(ROW). To delete the entire column, press 2(COL). u To delete the contents of all the cells in a spreadsheet 1. Press 3(DEL)3(ALL). 2. In response to the confirmation message that appears, press 1(Yes) to delete the data or 6(No) to cancel without deleting anything. u To insert a row or column of blank cells 1. Perform one of the following operations to specify the location of the insert and the number of rows or columns to be inserted. • To insert rows Starting with the row immediately below of the row where you want the insert to be performed, select the same number of rows that you want to insert. Example: To insert three rows above row 2, you could select A2:A4, B2:C4, etc. • To insert columns Starting with the column immediately to the right of the column where you want the insert to be performed, select the same number of columns that you want to insert. Example: To insert three columns to the left of column B, you could select B2:D4, B10:D20, etc. 2. Press 4(INS). • This will enter insert standby. If you decide you want to cancel the insert operation at this time, press J. 3. Press 1(ROW) to insert the applicable number of rows or 2(COL) to insert columns. • A Range ERROR occurs if an insert operation causes existing cells that contain data to move outside the range of A1:Z999. u To clear the contents of specific cells Select the cell or range of cells you want to clear and then press 5(CLR). 7-14 3. Using Special S • SHT Mode Commands The S • SHT mode has a number of special commands like CellSum(, which returns the sum of a range of cells, and CellIf(, which specifies branching conditions. These special commands can be used inside of formulas. k Special S • SHT Mode Command List “Input Key Operation” operations can be performed during cell input only. You can omit anything enclosed in brackets ([ ]) in the Syntax of each command. Command Description CellIf( (Branch Condition) Returns Expression 1 when the equality or inequality provided as the branch condition is true, and Expression 2 when it is false. Input Key Operation: 4(If) Syntax: CellIf(equality, expression 1, expression 2[)] or CellIf(inequality, expression 1, expression 2[)] Example: =CellIf(A1>B1, A1, B1) Returns the value of A1 when {Cell A1 value} > {Cell B1 value}. Otherwise, returns the value of B1. CellMin( (Cell Minimum Value) Returns the minimum value in a specified range of cells. Input Key Operation: 5(CEL)1(Min) Syntax: CellMin(start cell:end cell[)] Example: =CellMin(A3:C5) Returns the minimum value of the data in cell range A3:C5. CellMax( (Cell Maximum Value) Returns the maximum value in a specified range of cells. Input Key Operation: 5(CEL)2(Max) Syntax: CellMax(start cell:end cell[)] Example: =CellMax(A3:C5) Returns the maximum value of the data in cell range A3:C5. CellMean( (Mean of Cells) Returns the mean value in a specified range of cells.

Input Key Operation: 5(CEL)6(Prod) Syntax: CellProd(start cell:end cell[)] Example: =CellProd(B3:B5) Returns the product of the data in cell range B3:B5. k S • SHT Mode Command Example This example inputs the special S • SHT mode formula CellSum( into cell C1 in order to calculate the sum of all the data in cell range A1:B5. It is assumed that there is already data in the cell range A1:B5. 1. Move the cell cursor to cell C1 and then perform the following operation. a6(SYBL)5(=)JJ5(CEL)5(Sum) a1(A-E)1(A)bJJJ 3(:)a1(A-E)2(b)f!/( ) ) • You can perform the following operation, which uses the GRAB function (page 7-10) and CLIP function (page 7-6) in place of the underlined part in the above operation. J1(GRAB)4(TOP←) (Enters the GRAB mode and moves the cursor to A1.) !b(CLIP)ecccc (Specifies the selection range for the CLIP function.) w!/( ) ) 2. Press w to finalize input of the formula. 4. Drawing Statistical Graphs, and Performing Statistical and Regression Calculations When you want to check the correlation between two sets of data (such as temperature and the price of some product), trends become easier to spot if you draw a graph that uses one set of data as the x-axis and the other set of data as the y-axis. With the spreadsheet you can input the values for each set of data and draw a scatter plot or other types of graphs. Performing regression calculations on the data will produce a regression formula and correlation coefficient, and you can overlay a regression graph over the scatter plot. S • SHT mode graphing, statistical calculations, and regression calculations use the same functions as the STAT mode. The following shows an operation example that is unique to the S • SHT mode. 7-16 k Example of Statistical Graph Operations (GRPH Menu) Input the following data and draw a statistical graph (scatter plot in this example). 0.5, 1.2, 2.4, 4.0, 5.2 (x-axis data) –2.1, 0.3, 1.5, 2.0, 2.4 (y-axis data) u To input data and draw a statistical graph (scatter plot) 1. Input the statistical calculation data into the spreadsheet. • Here we will input the x-axis data into column A, and the y-axis data into column B. 2. Select the range of cells you want to graph (A1:B5). 3. Press 6(g)1(GRPH) to display the GRPH menu, and then press 1(GRPH1). • This will produce a scatter plot of the data in the range of cells you selected in step 2 of this procedure. • The graph shown here is what is produced under initial default S • SHT mode settings. You can change the configuration of graph settings on the screen that appears when you press 6(SET) on the GRPH menu. For details see “General Graph Settings Screen Operations” below. k General Graph Settings Screen Operations You can use the general graph setting screen to specify the range of data to be used for graphing, and to select the type of graph to be drawn. u To configure statistical graph settings 1. Input the statistical calculation data into the spreadsheet and then select the range of cells you want to graph. • Actually, the above step is not necessary at this point. You also could configure settings first before inputting data and selecting the range of cells to be graphed. 2.

The main memory is a work area where you can input data, perform calculations, and run programs. Data in the main memory is relatively safe, but it can be deleted by batteries going dead or when you perform a full reset. The storage memory uses “flash memory,” so data is safe even when power is interrupted. Normally, you should use the storage memory for data you need to store securely for long periods, loading data into the main memory only when you need it. You can also load an SD card into the calculator's card slot and use SD card memory as well. 1. Using the Memory Manager From the Main Menu, select the MEMORY icon to enter the MEMORY mode. • {MAIN} ... {displays main memory information} • {SMEM} ... {displays storage memory information} • {SD} ... {displays SD card memory information} • {BKUP} ... {main memory backup} • {OPT} ... {storage memory, SD card optimization} k Memory Information Screen The memory information screen shows information about one memory at a time: the calculator’s main memory or storage memory, or the SD card memory.

Before transferring the data to a computer, use the calculator’s MEMORY mode (page 8-1) to copy it from the calculator’s main memory to its storage memory. 2. Connect the calculator and computer, and open the calculator drive on the computer. • See “To establish a connection between the calculator and a computer” (page 10-1). 3. Copy, edit, delete, or add files as desired. • Use the same file operations that you normally do on your computer. • The @MainMem folder of the calculator drive is used to transfer calculator program data between the calculator and computer. For more information, see the following section titled “Editing Program Data on a Computer”. • When copying a calculator data file (filename extension g1m or g2m) from the computer to the calculator drive, do note copy it to the @MainMem folder. Copy it to a different location. 4. After you finish all the operations you want to perform, terminate the connection between the calculator and a computer. • See “To terminate the connection between the calculator and a computer” (page 10-2). 5. If you copied calculator data files from the computer to the calculator in step 3 of this procedure, copy those files to calculator main memory. • Use the calculators MEMORY mode (page 8-1) to copy the files to main memory. 10-3 Note • Copying a file to the storage memory can cause the connection between the calculator and computer to be dropped. If this happens, enter the MEMORY mode and execute an Optimize operation (page 8-10), and then re-establish a connection between the calculator and computer. k Editing Program Data on a Computer You can perform an operation on the calculator to convert programs you create with it to text file data, which you can then edit on a computer. After you finish editing the text file, you can then place it into the @MainMem\PROGRAM\ on the removable disk drive. Then when you terminate the USB connection between the calculator and computer, the text file will automatically be converted to a program file, which will be stored in the PROGRAM group in calculator main memory. After conversion, the text file will automatically be moved to the calculator storage memory folder named SAVE-F. For details about the rules that govern file names and other conversion issues, see “Program and Text File Conversion Rules” (page 6-7). u To use your computer to edit a program created on the calculator 1. Convert a program you created with the PRGM mode to a text file (“To convert a program to a text file”, page 6-8). 2. Connect the calculator and computer, and open the calculator drive on the computer. 3. Display the contents of the @MainMem\PROGRAM folder, and then use a text editor to open the text file you converted from a program in step 1 of this procedure. • If you are running Windows you could use Notepad, etc. With the Mac OS, you can use TextEdit, etc. 4. Perform the required edits. • For information about calculator commands and their corresponding special character strings, see “CASIO Scientific Function Calculator Special Commands ⇔ Text Conversion Table” (page 6-34). 5. After you are finished editing, save and close the text file. • Save the edits under a different file name, as required. If you use Save As to save your edits, be sure to save the new file in @MainMem\PROGRAM\. • Be sure to save the file in ASCII or ANSI code txt format. 6. Terminate the connection between the calculator and a computer • See “To terminate the connection between the calculator and a computer” (page 10-2). 10-4 k USB Connection Precautions • Depending on the operating system your computer is running, perform one of the following operations on the computer to terminate a connection with the calculator. - Windows: Click the “Safely Remove Hardware” icon in the task tray in the lower right corner of the display. On the menu that appears, select “USB mass storage device”. Check to make sure the “Safe To Remove Hardware” message is displayed. - Mac OS: Drag the “Untitled” drive icon to Trash. Check to make sure that the “Untitled” drive icon is no longer on your desktop. • Never use a computer operation to format the calculator drive. Doing so will cause a “File System ERROR” message to appear on the calculator screen after you terminate the USB connection between the calculator and computer. When this happens, you will not be able to start up the calculator unless you perform an Initialize All operation, which deletes all data currently in calculator memory. For details, see “File System ERROR” (page α-7). • When copying a file from your computer’s local disk to the calculator drive, it may take several minutes before copying starts. This is because copying automatically performs optimization of the calculator’s storage memory. It does not indicate malfunction. For information about storage memory optimization, see “Optimizing the Storage Memory or SD Card Memory” (page 8-10). • A USB connection between the calculator and a computer may be terminated automatically if the computer enters a power save mode, sleep mode, or any other standby state. 10-5 Chapter 11 Using SD Cards and SDHC Cards This calculator supports use of SD memory cards and SDHC memory cards. In this manual, all mentions of “SD card” refer to both SD memory cards and SDHC memory cards. You can use SD cards to store calculator data. You can copy main memory and storage memory data to and from an SD card. Important! • Use only an SD memory card or SDHC memory card. Operation is not guaranteed when another type of memory card is used. • Be sure to read the user documentation that comes with an SD card before using it. • Certain types of SD cards can slow down processing speeds. • Certain types of SD cards and operating conditions can shorten battery life. • SD cards have a write protect switch, which protects against accidental erasure of data. Note, however, that you need to remove write protection before you can copy data to or delete data from, or format a disk that is write-protected. • Static electric charge, electric noise, and other phenomena can delete or corrupt card data unexpectedly. Because of this you should always backup valuable data to other media (CD-R, CD-RW, hard disk, etc.) 1. Using an SD Card Important! • Always turn off the calculator before inserting or removing an SD card. • Note that a card needs to be oriented correctly (proper side must be facing upwards, the proper end must be inserted) when inserting it into the calculator. Trying to force card into the slot while it is oriented incorrectly can damage the card and slot. u To insert an SD card 1. Open the SD card cap on the right side of the calculator. 11-1 11 2. With the front of the SD card facing upwards (in the direction of the display side of the calculator), slide the card into the calculators slot as shown in the illustration below. Front Back 3. Replace the SD card cap and close it securely. Important! • Splash resistance, dust resistance, and shock resistance are maximized while the SD card cap is fully and securely closed. • Even a slight amount of foreign matter (a single hair, speck of dust, etc.) on the contact surface of the SD card cap can allow moisture and/or dust to get into the interior of the calculator. • Never insert anything other than SD cards into the card slot. Doing so can damage the calculator. • Should water or any foreign matter ever get into the card slot, immediately turn off the calculator, remove its batteries, and contact your original retailer or nearest CASIO authorized service center. u To remove the SD card 1. Open the SD card cap on the right side of the calculator. 2. Press in on the SD card and then release it. • This will cause the card to pop part way out of the slot. 3. Grasp the SD card with your fingers and pull it out of the slot. 4. Replace the SD card cap and close it securely. Important! • Never remove the SD card while data is being transferred to it. Doing so not only stops the data you are transferring to the card from being saved, it can also corrupt SD card contents. • Exerting undue force when removing an SD card can damage the card slot or the card. 11-2 2. Formatting an SD Card • Use the procedure under “Reset” (page 9-3) to format an SD card. 3. SD Card Precautions during Use • SD card problems can normally be corrected by reformatting the card. However, it is always a good idea to take along more than one SD card to avoid data storage problems. • Card formatting (initialization) is recommended before using a new SD card for the first time. • If an SD card has been formatted on a computer or other device, you can use it as-is without reformatting. A computer or other device also will be able to use an SD card that has been formatted with the calculator. • Never perform any of the following operations while the SD card is being accessed. - Removing the SD card - Connecting or disconnecting a USB cable - Turning off the calculator • Note that an SD card needs to be oriented correctly (proper side must be facing upwards, the proper end must be inserted) when inserting it into the calculator. Trying to force an SD card into the slot when it is oriented incorrectly can damage the card and slot. • Use of certain SD cards while calculator battery power is low can cause the display to go blank without displaying the low battery warning message. If this happens, replace the batteries. k Supported SD Cards SD Memory Cards Maximum capacity: 2 GB SDHC Memory Cards Maximum capacity: 32 GB Important! The time required for data writing and reading depends on the type of the SD card being used. For detailed information (specifications, features, etc.) about the SD card, contact the SD card manufacturer. 11-3 Appendix 1. Power Supply This calculator is powered by four AAA-size alkaline batteries LR03 (AM4), or four nickel-metal hydride batteries. If the following message appears on the display, immediately turn off the calculator and replace the batteries as instructed. If you try to continue using the calculator, it will automatically turn off in order to protect memory contents. You will not be able to turn power back on until you replace batteries. Be sure to replace the batteries at least once every one year, no matter how much you use the calculator during that time. The batteries that come with this calculator discharge slightly during shipment and storage. Because of this, they may require replacement sooner than the normal expected battery life. k Replacing Batteries Precautions: Incorrectly using batteries can cause them to burst or leak, possibly damaging the interior of the calculator. Note the following precautions: • Use only the batteries that are specifically listed in “Recommended Batteries” (page α-2). Never use any other type of batteries. • Be sure that the positive (+) and negative (–) poles of each battery are facing in the proper directions. • Never mix batteries of different brands or models. • When using nickel-metal hydride batteries, make sure to fully charge the batteries before use. • For details about how to charge nickel-metal hydride batteries, see the user documentation that comes with the batteries. • Note that the amount of operation between charges provided by nickel-metal hydride batteries may be shorter than the life of alkaline batteries. • Never mix batteries of different types. • Never mix old batteries and new ones. • Never leave dead batteries in the battery compartment. • Remove the batteries if you do not plan to use the calculator for long periods. • Never try to recharge the batteries supplied with the calculator. α-1 α • Do not expose batteries to direct heat, let them become shorted, or try to take them apart. (Should a battery leak, clean out the battery compartment of the calculator immediately, taking care to avoid letting the battery fluid come into direct contact with your skin.) Keep batteries out of the reach of small children. If swallowed, consult with a physician immediately. u Recommended Batteries AAA-size alkaline batteries: LR03 (AM4) AAA-size nickel-metal hydride batteries: Duracell rechargeable Energizer rechargeable SANYO eneloop u To replace the batteries • Never turn on the calculator while the batteries are removed or not loaded correctly.
