E-22 Inputting Expressions and Values k Inputting a Calculation Expression Using Standard Format Your calculator lets you input calculation expressions just as they are written. Then simply press the E key to execute it. The calculator automatically judges the calculation priority sequence for addition, subtraction, multiplication, and division, functions, and parentheses. Example: 2 (5 + 4) – 2 × (–3) = 2(5+4)2*y3E A Inputting a Function with Parenthesis When you input any of the functions shown below, it is automatically input with the open parenthesis ( ( ) character. Next, you need to input the argument and the closing parenthesis ( ) ). sin(, cos(, tan(, sin–1(, cos–1( , tan–1(, sinh(, cosh(, tanh(, sinh–1(, cosh–1(, tanh–1(, log(, ln(, e^(, 10^(, ^(, '(, 3'(, x'(, Abs(, Pol(, Rec(, Rnd( Example: sin 30 = z 1. t 2. “sin(” (fc), then E. 3. 30)E • Some commonly used functions can also be input using a direct key operation. Example: sin 30 = 1. 11(sin) 2. 30)E E-23 A Omitting the Multiplication Sign You can omit the multiplication sign (×) in any of the following cases. • Before an open parentheses ( ( ): 2 × (5 + 4), etc. • Before a function with parenthesis: 2 × sin(30), 2 × '(3), etc. • Before a variable name, constant, or random number: 20 × A, 2 × π, etc. A Final Closed Parenthesis You can omit one or more closed parentheses that come at the end of a calculation, immediately before the E key is pressed. For details, see “Omitting a Final Closed Parenthesis” on page E-29. A Displaying a Long Expression The display can show up to 14 characters at a time. Inputting the 15th character causes the expression to shift to the left. At this time, the ] indicator appears to the left of the expression, indicating that it runs off the left side of the screen. Input expression: 1111 + 2222 + 3333 + 444 Displayed portion: Cursor • When the ] indicator is displayed, you can scroll left and view the hidden part by pressing the d key. This will cause the ' indicator to appear to the right of the expression. At this time, you can use the e key to scroll back. A Number of Input Characters (Bytes) • You can input up to 99 bytes of data for a single expression. Basically, each key operation uses up one byte. A function that requires two key operations to input (like 11(sin)) also uses only one byte. E-24 • Normally the input cursor appears as a straight vertical (I) or horizontal ( ) flashing line on the display screen. When there are 10 or fewer bytes of input remaining in the current expression, the cursor changes shape to I to let you know. If the I cursor appears, terminate the expression at a convenient point and calculate the result. • Each expression in calculation history memory (page E-33) can contain up to 76 bytes of data. Up to 89 bytes of data can be assigned to each custom shortcut key (page E-94). k Correcting an Expression This section explains how to correct an expression as you are inputting it. The procedure you should use depends on whether you have insert or overwrite selected as the input mode. A About the Insert and Overwrite Input Modes With the insert mode, the displayed characters shift to the left to make room when you input a new character. With the overwrite mode, any new character you input replaces the character at the current cursor position. • The cursor is a vertical flashing line (I) when the insert mode is selected. The cursor is a horizontal flashing line ( ) when the overwrite mode is selected. • The initial default is the insert mode. You can switch between the insert mode and the overwrite mode by pressing 1Y(INS). A Changing the Character or Function You Just Input Example: To correct the expression 369 × 13 so it becomes 369 × 12 369*13 Y 2 E-25 E A Deleting a Character or Function Example: To correct the expression 369 × × 12 so it becomes 369 × 12 Insert Mode: 369**12 dd Y Overwrite Mode: 369**12 ddd Y A Correcting a Calculation Example: To correct cos(60) so it becomes sin(60) Insert Mode: 12(cos)60) dddY 11(sin) Overwrite Mode: 12(cos)60) dddd 11(sin) E-26 A Inserting input into a Calculation Always use the insert mode for this operation. Use d or e to move the cursor to the location where you want to insert new input, and then input what you want. k Displaying the Location of an Error If an error message (like “Math ERROR” or “Syntax ERROR”) appears when you press E, press d or e. This will display the part of the calculation where the error occurred, with the cursor positioned at the error location. You can then make necessary corrections. Example: When you input 14 ÷ 0 × 2 = by mistake instead of 14 ÷ 10 × 2 = Insert Mode: 14/0*2E Press e or d. This is causing the error. d1 E You can also exit the error screen by pressing A, which clears the calculation. E-27 Basic Calculations This section explains how to perform arithmetic and percent calculations. All calculations in this section are performed in the COMP Mode (g). k Arithmetic Calculations Use the +, -, *, and / keys to perform arithmetic calculations. Example: 7 × 8 – 4 × 5 = 36 7*8-4*5E • The calculator automatically judges the calculation priority sequence. For more information, see “Calculation Priority Sequence” on page E-134. A Number of Decimal Places and Number of Significant Digits You can specify a fixed number of decimal places and significant digits for the calculation result. Example: 1 ÷ 6 = Initial default setting (Norm1) FIX 3 decimal places (Fix3) SCI 3 significant digits (Sci3) • For more information, see “Configuring Settings” on page E-16. E-28 A Omitting a Final Closed Parenthesis You can omit any closed parenthesis ( ) ) immediately preceding operation of the E key at the end of a calculation.

When the calculation you are performing causes calculation history memory to become full, the oldest calculation is deleted automatically to make room for the new calculation. E-33 A Replay Function While a calculation result is on the display, you can press d or e to edit the expression you used for the previous calculation. Example: 4 × 3 + 2.5 = 14.5 4 × 3 – 7.1 = 4.9 4*3+2.5E A d YYYY -7.1E E-34 Using Calculator Memory Memory Name Answer Memory Description Stores the last calculation result obtained. Independent Memory Calculation results can be added to or subtracted from independent memory. The “M” display indicator indicates data in independent memory. Variables Six variables named A, B, C, D, X, and Y can be used for storage of individual values. VARS The following are the names of the financial calculation variables: n, I, PV, PMT, FV, P/Y, C/Y, PM1, PM2, Dys. This section uses the COMP Mode (g) to demonstrate how you can use memory. k Answer Memory (Ans) A Answer Memory Overview • Answer Memory contents are updated whenever you execute a calculation using any one of the following keys: E, 9, m, 1m(M–), t, or 1t(STO). Answer Memory can hold up to 15 digits. • Answer Memory contents do not change if an error occurs during the current calculation. • Answer Memory contents are maintained even if you press the A key, change the calculation mode, or turn off the calculator. • When multiple results are obtained (in polar coordinate calculations, when “ALL:Solve” is selected in the Simple Interest Mode, etc.), the result that is displayed at the top of the screen is the one stored in Answer Memory. E-35 A Using Answer Memory to Perform a Series of Calculations Example: To divide the result of 3 × 4 by 30 3*4E (Continuing)/30E Pressing / automatically inputs “Ans” command. • With the above procedure, you need to perform the second calculation immediately after the first one. If you need to recall Answer Memory contents after pressing A, press the G key. A Inputting Answer Memory Contents into an Expression Example: To perform the calculations shown below: 123 + 456 = 579 123+456E 789-GE E-36 789 – 579 = 210 k Independent Memory (M) You can add calculation results to or subtract results from independent memory. The “M” appears on the display when independent memory contains a value. A Independent Memory Overview • The following is a summary of the different operations you can perform using independent memory.

E-133 Technical Information k Calculation Priority Sequence The calculator performs calculations according to a calculation priority sequence. • Basically, calculations are performed from left to right. • Expressions within parentheses have the highest priority. • The following shows the priority sequence for each individual command. 1. Function with parentheses: Pol(, Rec( sin(, cos(, tan(, sin–1(, cos–1(, tan–1(, sinh(, cosh(, tanh(, sinh–1(, cosh–1(, tanh–1( log(, ln(, e^(, 10^(, '(, 3'( Abs( Rnd( 2. Functions preceded by values, powers, power roots: x2, x3, x–1, x!, °, r, g, ^(, x'( Percent: % 3. Prefix symbol: (–) (negative sign) 4. Statistical estimated value calculation: m, n, m1, m2 5. Permutations, combinations: nPr, nCr 6. Multiplication and division: ×, ÷ Multiplication where sign is omitted: Multiplication sign omitted immediately before π, e, variables (2π, 5A, πA, etc.), functions with parentheses (2'(3), Asin(30), etc.) 7. Addition and subtraction: +, – If a calculation contains a negative value, you may need to enclose the negative value in parentheses. If you want to square the value –2, for example, you need to input: (–2)2. This is because x2 is a function preceded by a value (Priority 2, above), whose priority is greater than the negative sign, which is a prefix symbol (Priority 3). E-134 Example: –22 = –4 1. y2 2. t 3. “2” (fc), then E. 4. E (–2)2 = 4 1. (y2) 2. t 3. “2” (fc), then E. 4. E Multiplication and division, and multiplication where the sign is omitted are the same priority (Priority 6), so these operations are performed from left to right when both types are mixed in the same calculation. Enclosing an operation within parentheses causes it to be performed first, so the use of parentheses can result in different calculation results. Example: 1 ÷ 2π = 1.570796327 1 ÷ (2π) = 0.1591549431 1/215(π)E 1/(215(π)) E E-135 k Stack Limitations This calculator uses memory areas called stacks to temporarily store lower calculation priority sequence values, commands, and functions. The numeric stack has 10 levels and the command stack has 24 levels, as shown in the illustration below. 3 2 1 1 2 3 4 Numeric Stack 1 2 4 5 6 5 7 Command Stack 1 2 3 2 3 4 3 4 5 4 5 4 5 6 7 A Stack ERROR occurs when the calculation you are performing causes the capacity of either stack to be exceeded. E-136 k Calculation Ranges, Number of Digits, and Precision The calculation range, number of digits used for internal calculation, and calculation precision depends on the type of calculation you are performing. Calculation Range and Precision Calculation Range ±1 × 10–99 to ±9.999999999 × 1099 or 0 Number of Digits for 15 digits Internal Calculation In general, ±1 at the 10th digit for a single calculation. Precision for exponential display is ±1 at the least significant digit. Errors are cumulative in the case of consecutive calculations.

Math ERROR k Error Messages The calculator will display an error message when a result exceeds the calculation range, when you attempt an illegal input, or whenever any other similar problem occurs. A When an error message appears... The following are general operations you can use when any error message appears. • Pressing d or e displays to the calculation expression editing screen you were using before the error message appeared, with the cursor located at the position of the error. For more information, see “Displaying the Location of an Error” on page E-27. • Pressing A clears the calculation expression you input before the error message appeared. You can then reinput and re-execute the calculation, if you want. Note that in this case, the original calculation will not be retained in calculation history memory. • See “Special Financial Calculation Error Messages” (E-139) for information about error messages that may occur during financial calculations. E-140 Math ERROR Cause • The intermediate or final result of the calculation you are performing exceeds the allowable calculation range. • Your input exceeds the allowable input range. • The calculation you are performing contains an illegal mathematical operation (such as division by zero). Action • Check the input values to ensure they are within the applicable calculation range. See “Calculation Ranges, Numbers of Digits, and Precision” on page E-137. • When using independent memory or a variable as the argument of a function, make sure that the memory or variable value is within the allowable range for the function. Stack ERROR Cause • The calculation you are performing has caused the capacity of the numeric stack or the command stack to be exceeded. Action • Simplify the calculation expression so it does not exceed the capacity of the stack. • Try splitting the calculation into two or more parts. Syntax ERROR Cause • There is a problem with the format of the calculation you are performing. Action • Make necessary corrections. Insufficient MEM Error Cause • The number of bytes required to store the calculation you are inputting exceeds the maximum capacity (89 bytes) for Shortcut key assignment. Action • Divide the calculation into smaller parts. • Normally the input cursor appears as a straight vertical (I) or horizontal ( ) flashing line on the display screen. When there are 10 or fewer bytes of input remaining in E-141 the current expression, the cursor changes shape to I to let you know. If the I cursor appears, terminate the expression at a convenient point and calculate the result. Argument ERROR Cause • Financial conditions insufficient for financial calculations (such as YR1 > 12). Action • Check the input values to ensure they are within the applicable calculation range. See “Calculation Ranges, Numbers of Digits, and Precision” on page E-137. k Before assuming malfunction of the calculator... Perform the following steps whenever an error occurs during a calculation or when calculation results are not what you expected. If one step does not correct the problem, move on to the next step. Note that you should make separate copies of important data before performing these steps. 1. Check the calculation expression to make sure that it does not contain any errors. 2. Make sure that you are using the correct mode for the type of calculation you are trying to perform. 3. If the above steps do not correct your problem, press the O key. This will cause the calculator to perform a routine that checks whether calculation functions are operating correctly. If the calculator discovers any abnormality, it automatically initializes the calculation mode and clears memory contents. For details about initialized settings, see “Initializing the Calculator” on page E-3. 4. Initialize all modes and settings by performing the following operation: (1) O19(CLR) (2) “All:EXE” (fc), then E. (3) E(Yes) (4) A E-142 Reference k Power Requirements and Battery Replacement FC-200V Your calculator uses a TWO WAY POWER system that combines a solar cell with G13 type button battery (LR44). Normally, calculators equipped with a solar cell alone can operate only when relatively bright light is present. The TWO WAY POWER system, however, lets you continue to use the calculator as long as there is enough light to read the display. A Replacing the Battery Dim display figures when available lighting is dim or failure of anything to appear on the display immediately when you turn on the calculator indicates that button battery power is low. Note that you will not be able to use the calculator if its button battery is dead. When any of these symptoms occur, replace the button battery. Even if the calculator is operating normally, replace the battery at least once every three years. Important! • Removing the button battery from the calculator causes independent memory contents and values assigned to variables to be cleared. 1. Press 1A(OFF) to turn off the calculator. • To ensure that you do not accidentally turn on power while replacing the battery, slide the hard case onto the front of the calculator. 2. On the back of the calculator, remove the screw and the battery cover. 3. Remove the old battery. E-143 Screw 4. Wipe a new battery with a dry cloth, and then load it into the calculator with its positive k side facing upwards (so you can see it). 5. Replace the battery cover and secure it in place with its screw. 6. Perform the following key operation: (1) O19(CLR) (2) “All:EXE” (fc), then E (3) E(Yes) (4) A • Make sure you perform the above key operation. Do not skip it. • Replacing the battery initializes the calculator, including the custom shortcut keys and function shortcut keys. See “Initializing the Calculator” (page E-3) for more information. FC-100V This calculator is powered by a single AAA-size battery (R03 (UM-4)). A Replacing the Battery Dim figures on the display of the calculator indicate that battery power is low. Continued use of the calculator when the battery is low can result in improper operation. Replace the battery as soon as possible when display figures becomes dim. Even if the calculator is operating normally, replace the battery at least once every two years.
