• NORM2: 0.01 ≤ x ≤ 9999999999
Angular Unit Conversions
SCIENTIFIC CALCULATIONS
• Press m0 to select the normal mode.
• In each example, press ª to clear the display. If the FIX, SCI,
or ENG indicator is displayed, clear the indicator by selecting
‘NORM1’ from the SET UP menu.
Arithmetic Operations
• The closing parenthesis ) just before = or ; may be
omitted.
Constant Calculations
• In constant calculations, the addend becomes a constant. Subtraction and division are performed in the same manner. For
multiplication, the multiplicand becomes a constant.
• In the constants calculations, constants will be displayed as K.
Functions
• Refer to the calculation examples of each function.
• Before starting calculations, specify the angular unit.
Differential/Integral Functions
Differential and integral calculations are only available in the normal mode. For calculation conditions such as the x value in differential calculation or the initial point in integral calculation, only
numerical values can be entered and equations such as 22 cannot
be specified. It is possible to reuse the same equation over and
over again and to recalculate by only changing the conditions without re-entering the equation.
• Performing a calculation will clear the value in the X memory.
• When performing a differential calculation, enter the formula first and
then enter the x value in differential calculation and the minute interval
(dx). If a numerical value is not specified for minute interval, x≠0 will be
x×10–5 and x=0 will be 10–5 from the value of the numeric derivative.
• When performing an integral calculation, enter the formula first
and then enter a range of integral (a, b) and subintervals (n). If a
numerical value is not specified for subintervals, calculation will
be performed using n=100.
Since differential and integral calculations are performed based on
the following equations, correct results may not be obtained, in
certain rare cases, when performing special calculations that contain discontinuous points.
[Random Integer]
An integer between 0 and 99 can be generated randomly by pressing @`3®.
Arithmetic operations and memory calculations can be performed
using fractions, and conversion between a decimal number and a
fraction.
• If the number of digits to be displayed is greater than 10, the
number is converted to and displayed as a decimal number.
Binary, Pental, Octal, Decimal, and Hexadecimal
Operations (N-Base)
Conversions can be performed between N-base numbers. The
four basic arithmetic operations, calculations with parentheses
and memory calculations can also be performed, along with the
logical operations AND, OR, NOT, NEG, XOR and XNOR on
binary, pental, octal and hexadecimal numbers.
Conversion to each system is performed by the following keys:
@ê (“ ” appears.), @û (“ ” appears.), @î
(“ ” appears.), @ì (“ ” appears.), @í (“ ”, “ ”,
“ ” and “ ” disappear.)
Note: The hexadecimal numbers A – F are entered by pressing
ß, ™, L, ÷, l, and I, and displayed
as follows:
A → ï, B → ∫, C → ó, D → ò, E → ô, F → ö
In the binary, pental, octal, and hexadecimal systems, fractional
parts cannot be entered. When a decimal number having a fractional part is converted into a binary, pental, octal, or hexadecimal number, the fractional part will be truncated. Likewise, when
the result of a binary, pental, octal, or hexadecimal calculation
includes a fractional part, the fractional part will be truncated. In
the binary, pental, octal, and hexadecimal systems, negative numbers are displayed as a complement.
Time, Decimal and Sexagesimal Calculations
Conversion between decimal and sexagesimal numbers can be
performed, and, while using sexagesimal numbers, conversion to
seconds and minutes notation. The four basic arithmetic operations and memory calculations can be performed using the
sexagesimal system. Notation for sexagesimal is as follows:
degree
second
minute

Modify Function
Calculation results are internally obtained in scientific notation
with up to 14 digits for the mantissa. However, since calculation
results are displayed in the form designated by the display notation and the number of decimal places indicated, the internal
calculation result may differ from that shown in the display. By
using the modify function, the internal value is converted to match
that of the display, so that the displayed value can be used
without change in subsequent operations.

Single-variable statistics
Linear regression calculation
Quadratic regression calculation
Exponential regression calculation
Logarithmic regression calculation
Power regression calculation
Inverse regression calculation
The following statistics can be obtained for each statistical calculation (refer to the table below):
Linear regression calculation
Statistics of Q and W and, in addition, estimate of y for a given x
(estimate y´) and estimate of x for a given y (estimate x´)
Exponential regression, Logarithmic regression,
Power regression, and Inverse regression calculation
Statistics of Q and W. In addition, estimate of y for a given x and
estimate of x for a given y. (Since the calculator converts each
formula into a linear regression formula before actual calculation
takes place, it obtains all statistics, except coefficients a and b,
from converted data rather than entered data.)
Quadratic regression calculation
Statistics of Q and W and coefficients a, b, c in the quadratic
regression formula (y = a + bx + cx2). (For quadratic regression
calculations, no correlation coefficient (r) can be obtained.) When
there are two x´ values, press @≠.
When performing calculations using a, b and c, only one numeric
value can be held.
Q
Solver Function
The x value can be found that reduces an entered equation to “0”.
• This function uses Newton’s method to obtain an approximation. Depending on the function (e.g. periodic) or ‘Start’ value,
an error may occur (Error 2) due to there being no convergence
to the solution for the equation.
• The value obtained by this function may include a margin of
error. If it is larger than acceptable, recalculate the solution
after changing ‘Start’ and dx values.
• Change the ‘Start’ value (e.g. to a negative value) or dx value
(e.g. to a smaller value) if:
• no solution can be found (Error 2).
• more than two solutions appear to be possible (e.g. a cubic
equation).
• to improve the arithmetic precision.
• The calculation result is automatically stored in the X memory.
[Performing Solver function]
Q Press m0.
W Input a formula with an x variable.
E Press ∑0.
R Input ‘Start’ value and press ®. The default value is “0”.
T Input dx value (minute interval).
Y Press ®.
SIMULATION CALCULATION (ALGB)
If you have to find a value consecutively using the same formula,
such as plotting a curve line for 2x2 + 1, or finding the variable for
2x + 2y =14, once you enter the equation, all you have to do is to
specify the value for the variable in the formula.
Usable variables: A-F, M, X and Y
Unusable functions: Random function
• Simulation calculations can only be executed in the normal
mode.
• Calculation ending instructions other than = cannot be used.
Performing Calculations
Q Press m0.
W Input a formula with at least one variable.
E Press @≤.
R Variable input screen will appear. Input the value of the flashing
variable, then press ® to confirm. The calculation result will
be displayed after entering the value for all used variables.
• Only numerical values are allowed as variables. Input of
formulas is not permitted.
• Upon completing the calculation, press @≤ to perform calculations using the same formula.

• In constant calculations, the addend becomes a constant. Subtraction and division are performed in the same manner. For
multiplication, the multiplicand becomes a constant.
• In the constants calculations, constants will be displayed as K.
Functions
• Refer to the calculation examples of each function.
• Before starting calculations, specify the angular unit.
Differential/Integral Functions
Differential and integral calculations are only available in the normal mode. For calculation conditions such as the x value in differential calculation or the initial point in integral calculation, only
numerical values can be entered and equations such as 22 cannot
be specified. It is possible to reuse the same equation over and
over again and to recalculate by only changing the conditions without re-entering the equation.
• Performing a calculation will clear the value in the X memory.
• When performing a differential calculation, enter the formula first and
then enter the x value in differential calculation and the minute interval
(dx). If a numerical value is not specified for minute interval, x≠0 will be
x×10–5 and x=0 will be 10–5 from the value of the numeric derivative.
• When performing an integral calculation, enter the formula first
and then enter a range of integral (a, b) and subintervals (n). If a
numerical value is not specified for subintervals, calculation will
be performed using n=100.
Since differential and integral calculations are performed based on
the following equations, correct results may not be obtained, in
certain rare cases, when performing special calculations that contain discontinuous points.
[Random Integer]
An integer between 0 and 99 can be generated randomly by pressing @`3®.
Arithmetic operations and memory calculations can be performed
using fractions, and conversion between a decimal number and a
fraction.
• If the number of digits to be displayed is greater than 10, the
number is converted to and displayed as a decimal number.
Binary, Pental, Octal, Decimal, and Hexadecimal
Operations (N-Base)
Conversions can be performed between N-base numbers. The
four basic arithmetic operations, calculations with parentheses
and memory calculations can also be performed, along with the
logical operations AND, OR, NOT, NEG, XOR and XNOR on
binary, pental, octal and hexadecimal numbers.
Conversion to each system is performed by the following keys:
@ê (“ ” appears.), @û (“ ” appears.), @î
(“ ” appears.), @ì (“ ” appears.), @í (“ ”, “ ”,
“ ” and “ ” disappear.)
Note: The hexadecimal numbers A – F are entered by pressing
ß, ™, L, ÷, l, and I, and displayed
as follows:
A → ï, B → ∫, C → ó, D → ò, E → ô, F → ö
In the binary, pental, octal, and hexadecimal systems, fractional
parts cannot be entered. When a decimal number having a fractional part is converted into a binary, pental, octal, or hexadecimal number, the fractional part will be truncated. Likewise, when
the result of a binary, pental, octal, or hexadecimal calculation
includes a fractional part, the fractional part will be truncated. In
the binary, pental, octal, and hexadecimal systems, negative numbers are displayed as a complement.
Time, Decimal and Sexagesimal Calculations
Conversion between decimal and sexagesimal numbers can be
performed, and, while using sexagesimal numbers, conversion to
seconds and minutes notation. The four basic arithmetic operations and memory calculations can be performed using the
sexagesimal system. Notation for sexagesimal is as follows:
degree
second
minute

Modify Function
Calculation results are internally obtained in scientific notation
with up to 14 digits for the mantissa. However, since calculation
results are displayed in the form designated by the display notation and the number of decimal places indicated, the internal
calculation result may differ from that shown in the display. By
using the modify function, the internal value is converted to match
that of the display, so that the displayed value can be used
without change in subsequent operations.

Single-variable statistics
Linear regression calculation
Quadratic regression calculation
Exponential regression calculation
Logarithmic regression calculation
Power regression calculation
Inverse regression calculation
The following statistics can be obtained for each statistical calculation (refer to the table below):
Linear regression calculation
Statistics of Q and W and, in addition, estimate of y for a given x
(estimate y´) and estimate of x for a given y (estimate x´)
Exponential regression, Logarithmic regression,
Power regression, and Inverse regression calculation
Statistics of Q and W. In addition, estimate of y for a given x and
estimate of x for a given y. (Since the calculator converts each
formula into a linear regression formula before actual calculation
takes place, it obtains all statistics, except coefficients a and b,
from converted data rather than entered data.)
Quadratic regression calculation
Statistics of Q and W and coefficients a, b, c in the quadratic
regression formula (y = a + bx + cx2). (For quadratic regression
calculations, no correlation coefficient (r) can be obtained.) When
there are two x´ values, press @≠.
When performing calculations using a, b and c, only one numeric
value can be held.
Q
Solver Function
The x value can be found that reduces an entered equation to “0”.
• This function uses Newton’s method to obtain an approximation. Depending on the function (e.g. periodic) or ‘Start’ value,
an error may occur (Error 2) due to there being no convergence
to the solution for the equation.
• The value obtained by this function may include a margin of
error. If it is larger than acceptable, recalculate the solution
after changing ‘Start’ and dx values.
• Change the ‘Start’ value (e.g. to a negative value) or dx value
(e.g. to a smaller value) if:
• no solution can be found (Error 2).
• more than two solutions appear to be possible (e.g. a cubic
equation).
• to improve the arithmetic precision.
• The calculation result is automatically stored in the X memory.
[Performing Solver function]
Q Press m0.
W Input a formula with an x variable.
E Press ∑0.
R Input ‘Start’ value and press ®. The default value is “0”.
T Input dx value (minute interval).
Y Press ®.
SIMULATION CALCULATION (ALGB)
If you have to find a value consecutively using the same formula,
such as plotting a curve line for 2x2 + 1, or finding the variable for
2x + 2y =14, once you enter the equation, all you have to do is to
specify the value for the variable in the formula.
Usable variables: A-F, M, X and Y
Unusable functions: Random function
• Simulation calculations can only be executed in the normal
mode.
• Calculation ending instructions other than = cannot be used.
Performing Calculations
Q Press m0.
W Input a formula with at least one variable.
E Press @≤.
R Variable input screen will appear. Input the value of the flashing
variable, then press ® to confirm. The calculation result will
be displayed after entering the value for all used variables.
• Only numerical values are allowed as variables. Input of
formulas is not permitted.
• Upon completing the calculation, press @≤ to perform calculations using the same formula.

*5 buffers in STAT mode and complex number mode.
• Data items exceeded 100 in the statistics mode.
In the statistical calculation formulas, an error will occur when:
• The absolute value of the intermediate result or calculation result
is equal to or greater than 1 × 10100.
• The denominator is zero.
• An attempt is made to take the square root of a negative number.
• No solution exists in the quadratic regression calculation.
Normal Probability Calculations
• P(t), Q(t), and R(t) will always take positive values, even when
t<0, because these functions follow the same principle used
when solving for an area.
Values for P(t), Q(t), and R(t) are given to six decimal places.
SIMULTANEOUS LINEAR EQUATIONS
Simultaneous linear equation with two unknowns (2-VLE) or with
three unknowns (3-VLE) may be solved using this function.
Q 2-VLE: m20
W 3-VLE: m21
• If the determinant D = 0, an error occurs.
• If the absolute value of an intermediate result or calculation result

or x-coordinate +Ü y-coordinate
W Polar coordinates
rÖθ
r: absolute value
θ: argument
• On selecting another mode, the imaginary part of any complex
number stored in the independent memory (M) will be cleared.
• A complex number expressed in rectangular coordinates with the
y-value equal to zero, or expressed in polar coordinates with the
angle equal to zero, is treated as a real number.
• Press ∑0 to return the complex conjugate of the specified complex number.
ERROR AND CALCULATION RANGES
Errors
An error will occur if an operation exceeds the calculation ranges,
or if a mathematically illegal operation is attempted. When an error
occurs, pressing < (or >) automatically moves the cursor
back to the place in the equation where the error occurred. Edit the
equation or press ª to clear the equation.
Equation too long (Error 4):
• The equation exceeded its maximum input buffer (142 characters).
An equation must be shorter than 142 characters.
Equation recall error (Error 5):
• The stored equation contains a function not available in the mode
used to recall the equation. For example, if a numerical value with
numbers other than 0 and 1 is stored as a decimal, etc., it cannot be
recalled when the calculator is set to binary.
• Make sure that the display appears as shown below. If the
display does not appear as shown, remove the batteries, reinstall them and check the display once again.

• Within the ranges specified, this calculator is accurate to ±1
of the least significant digit of the mantissa. However, a
calculation error increases in continuous calculations due
to accumulation of each calculation error. (This is the same
for yx, x¿ , ex, ln, etc., where continuous calculations are
performed internally.)
Additionally, a calculation error will accumulate and become
larger in the vicinity of inflection points and singular points
of functions.
• Calculation ranges

be specified. It is possible to reuse the same equation over and
over again and to recalculate by only changing the conditions without re-entering the equation.
• Performing a calculation will clear the value in the X memory.
• When performing a differential calculation, enter the formula first and
then enter the x value in differential calculation and the minute interval
(dx). If a numerical value is not specified for minute interval, x≠0 will be
x×10–5 and x=0 will be 10–5 from the value of the numeric derivative.
• When performing an integral calculation, enter the formula first
and then enter a range of integral (a, b) and subintervals (n). If a
numerical value is not specified for subintervals, calculation will
be performed using n=100.
Since differential and integral calculations are performed based on
the following equations, correct results may not be obtained, in
certain rare cases, when performing special calculations that contain discontinuous points.
[Random Integer]
An integer between 0 and 99 can be generated randomly by pressing @`3®.
Arithmetic operations and memory calculations can be performed
using fractions, and conversion between a decimal number and a
fraction.
• If the number of digits to be displayed is greater than 10, the
number is converted to and displayed as a decimal number.
Binary, Pental, Octal, Decimal, and Hexadecimal
Operations (N-Base)
Conversions can be performed between N-base numbers. The
four basic arithmetic operations, calculations with parentheses
and memory calculations can also be performed, along with the
logical operations AND, OR, NOT, NEG, XOR and XNOR on
binary, pental, octal and hexadecimal numbers.
Conversion to each system is performed by the following keys:
@ê (“ ” appears.), @û (“ ” appears.), @î
(“ ” appears.), @ì (“ ” appears.), @í (“ ”, “ ”,
“ ” and “ ” disappear.)
Note: The hexadecimal numbers A – F are entered by pressing
ß, ™, L, ÷, l, and I, and displayed
as follows:
A → ï, B → ∫, C → ó, D → ò, E → ô, F → ö
In the binary, pental, octal, and hexadecimal systems, fractional
parts cannot be entered. When a decimal number having a fractional part is converted into a binary, pental, octal, or hexadecimal number, the fractional part will be truncated. Likewise, when
the result of a binary, pental, octal, or hexadecimal calculation
includes a fractional part, the fractional part will be truncated. In
the binary, pental, octal, and hexadecimal systems, negative numbers are displayed as a complement.
Time, Decimal and Sexagesimal Calculations
Conversion between decimal and sexagesimal numbers can be
performed, and, while using sexagesimal numbers, conversion to
seconds and minutes notation. The four basic arithmetic operations and memory calculations can be performed using the
sexagesimal system. Notation for sexagesimal is as follows:
degree
second
minute

Modify Function
Calculation results are internally obtained in scientific notation
with up to 14 digits for the mantissa. However, since calculation
results are displayed in the form designated by the display notation and the number of decimal places indicated, the internal
calculation result may differ from that shown in the display. By
using the modify function, the internal value is converted to match
that of the display, so that the displayed value can be used
without change in subsequent operations.

Single-variable statistics
Linear regression calculation
Quadratic regression calculation
Exponential regression calculation
Logarithmic regression calculation
Power regression calculation
Inverse regression calculation
The following statistics can be obtained for each statistical calculation (refer to the table below):
Linear regression calculation
Statistics of Q and W and, in addition, estimate of y for a given x
(estimate y´) and estimate of x for a given y (estimate x´)
Exponential regression, Logarithmic regression,
Power regression, and Inverse regression calculation
Statistics of Q and W. In addition, estimate of y for a given x and
estimate of x for a given y. (Since the calculator converts each
formula into a linear regression formula before actual calculation
takes place, it obtains all statistics, except coefficients a and b,
from converted data rather than entered data.)
Quadratic regression calculation
Statistics of Q and W and coefficients a, b, c in the quadratic
regression formula (y = a + bx + cx2). (For quadratic regression
calculations, no correlation coefficient (r) can be obtained.) When
there are two x´ values, press @≠.
When performing calculations using a, b and c, only one numeric
value can be held.
Q
Solver Function
The x value can be found that reduces an entered equation to “0”.
• This function uses Newton’s method to obtain an approximation. Depending on the function (e.g. periodic) or ‘Start’ value,
an error may occur (Error 2) due to there being no convergence
to the solution for the equation.
• The value obtained by this function may include a margin of
error. If it is larger than acceptable, recalculate the solution
after changing ‘Start’ and dx values.
• Change the ‘Start’ value (e.g. to a negative value) or dx value
(e.g. to a smaller value) if:
• no solution can be found (Error 2).
• more than two solutions appear to be possible (e.g. a cubic
equation).
• to improve the arithmetic precision.
• The calculation result is automatically stored in the X memory.
[Performing Solver function]
Q Press m0.
W Input a formula with an x variable.
E Press ∑0.
R Input ‘Start’ value and press ®. The default value is “0”.
T Input dx value (minute interval).
Y Press ®.
SIMULATION CALCULATION (ALGB)
If you have to find a value consecutively using the same formula,
such as plotting a curve line for 2x2 + 1, or finding the variable for
2x + 2y =14, once you enter the equation, all you have to do is to
specify the value for the variable in the formula.
Usable variables: A-F, M, X and Y
Unusable functions: Random function
• Simulation calculations can only be executed in the normal
mode.
• Calculation ending instructions other than = cannot be used.
Performing Calculations
Q Press m0.
W Input a formula with at least one variable.
E Press @≤.
R Variable input screen will appear. Input the value of the flashing
variable, then press ® to confirm. The calculation result will
be displayed after entering the value for all used variables.
• Only numerical values are allowed as variables. Input of
formulas is not permitted.
• Upon completing the calculation, press @≤ to perform calculations using the same formula.

Depth error (Error 3):
• The available number of buffers was exceeded. (There are 10 buffers*
for numeric values and 24 buffers for calculation instructions).
*5 buffers in STAT mode and complex number mode.
• Data items exceeded 100 in the statistics mode.
In the statistical calculation formulas, an error will occur when:
• The absolute value of the intermediate result or calculation result
is equal to or greater than 1 × 10100.
• The denominator is zero.
• An attempt is made to take the square root of a negative number.
• No solution exists in the quadratic regression calculation.
Normal Probability Calculations
• P(t), Q(t), and R(t) will always take positive values, even when
t<0, because these functions follow the same principle used
when solving for an area.
Values for P(t), Q(t), and R(t) are given to six decimal places.
SIMULTANEOUS LINEAR EQUATIONS
Simultaneous linear equation with two unknowns (2-VLE) or with
three unknowns (3-VLE) may be solved using this function.
Q 2-VLE: m20
W 3-VLE: m21
• If the determinant D = 0, an error occurs.
• If the absolute value of an intermediate result or calculation result
is 1 × 10100 or more, an error occurs.
• Coefficients ( a1, etc.) can be entered using ordinary arithmetic
operations.
• To clear the entered coefficients, press @c.
• Pressing ® when the determinant D is in the display recalls
the coefficients. Each time ® is pressed, a coefficient is
displayed in the order of input, allowing the entered coefficients
to be verified (by pressing @®, coefficients are displayed
in reverse order.) To correct a particular coefficient being displayed, enter the correct value and then press ®.
QUADRATIC AND CUBIC EQUATION SOLVERS

The display can be switched between imaginary and real parts
by pressing @≠.
COMPLEX NUMBER CALCULATIONS
To carry out addition, subtraction, multiplication, and division using
complex numbers, press m3 to select the complex number
mode.
Results of complex number calculations are expressed in two modes:
Q @}: Rectangular coordinate mode (xy appears.)
W @{: Polar coordinate mode (r θ appears.)
Complex number entry
Q Rectangular coordinates
x-coordinate + y-coordinate Ü
or x-coordinate +Ü y-coordinate
W Polar coordinates

r: absolute value
θ: argument
• On selecting another mode, the imaginary part of any complex
number stored in the independent memory (M) will be cleared.
• A complex number expressed in rectangular coordinates with the
y-value equal to zero, or expressed in polar coordinates with the
angle equal to zero, is treated as a real number.
• Press ∑0 to return the complex conjugate of the specified complex number.
ERROR AND CALCULATION RANGES
Errors
An error will occur if an operation exceeds the calculation ranges,
or if a mathematically illegal operation is attempted. When an error
occurs, pressing < (or >) automatically moves the cursor
back to the place in the equation where the error occurred. Edit the
equation or press ª to clear the equation.
Equation too long (Error 4):
• The equation exceeded its maximum input buffer (142 characters).
An equation must be shorter than 142 characters.
Equation recall error (Error 5):
• The stored equation contains a function not available in the mode
used to recall the equation. For example, if a numerical value with
numbers other than 0 and 1 is stored as a decimal, etc., it cannot be
recalled when the calculator is set to binary.
• Make sure that the display appears as shown below. If the
display does not appear as shown, remove the batteries, reinstall them and check the display once again.

SCIENTIFIC CALCULATIONS
• Press m0 to select the normal mode.
• In each example, press ª to clear the display. If the FIX, SCI,
or ENG indicator is displayed, clear the indicator by selecting
‘NORM1’ from the SET UP menu.
Arithmetic Operations
• The closing parenthesis ) just before = or ; may be
omitted.
Constant Calculations
• In constant calculations, the addend becomes a constant. Subtraction and division are performed in the same manner. For
multiplication, the multiplicand becomes a constant.
• In the constants calculations, constants will be displayed as K.
Functions
• Refer to the calculation examples of each function.
• Before starting calculations, specify the angular unit.
Differential/Integral Functions
Differential and integral calculations are only available in the normal mode. For calculation conditions such as the x value in differential calculation or the initial point in integral calculation, only
numerical values can be entered and equations such as 22 cannot
be specified. It is possible to reuse the same equation over and
over again and to recalculate by only changing the conditions without re-entering the equation.
• Performing a calculation will clear the value in the X memory.
• When performing a differential calculation, enter the formula first and
then enter the x value in differential calculation and the minute interval
(dx). If a numerical value is not specified for minute interval, x≠0 will be
x×10–5 and x=0 will be 10–5 from the value of the numeric derivative.
• When performing an integral calculation, enter the formula first
and then enter a range of integral (a, b) and subintervals (n). If a
numerical value is not specified for subintervals, calculation will
be performed using n=100.
Since differential and integral calculations are performed based on
the following equations, correct results may not be obtained, in
certain rare cases, when performing special calculations that contain discontinuous points.
[Random Integer]
An integer between 0 and 99 can be generated randomly by pressing @`3®.
Arithmetic operations and memory calculations can be performed
using fractions, and conversion between a decimal number and a
fraction.
• If the number of digits to be displayed is greater than 10, the
number is converted to and displayed as a decimal number.
Binary, Pental, Octal, Decimal, and Hexadecimal
Operations (N-Base)
Conversions can be performed between N-base numbers. The
four basic arithmetic operations, calculations with parentheses
and memory calculations can also be performed, along with the
logical operations AND, OR, NOT, NEG, XOR and XNOR on
binary, pental, octal and hexadecimal numbers.
Conversion to each system is performed by the following keys:
@ê (“ ” appears.), @û (“ ” appears.), @î
(“ ” appears.), @ì (“ ” appears.), @í (“ ”, “ ”,
“ ” and “ ” disappear.)
Note: The hexadecimal numbers A – F are entered by pressing
ß, ™, L, ÷, l, and I, and displayed
as follows:
A → ï, B → ∫, C → ó, D → ò, E → ô, F → ö
In the binary, pental, octal, and hexadecimal systems, fractional
parts cannot be entered. When a decimal number having a fractional part is converted into a binary, pental, octal, or hexadecimal number, the fractional part will be truncated. Likewise, when
the result of a binary, pental, octal, or hexadecimal calculation
includes a fractional part, the fractional part will be truncated. In
the binary, pental, octal, and hexadecimal systems, negative numbers are displayed as a complement.
Time, Decimal and Sexagesimal Calculations
Conversion between decimal and sexagesimal numbers can be
performed, and, while using sexagesimal numbers, conversion to
seconds and minutes notation. The four basic arithmetic operations and memory calculations can be performed using the
sexagesimal system. Notation for sexagesimal is as follows:
degree

Modify Function
Calculation results are internally obtained in scientific notation
with up to 14 digits for the mantissa. However, since calculation
results are displayed in the form designated by the display notation and the number of decimal places indicated, the internal
calculation result may differ from that shown in the display. By
using the modify function, the internal value is converted to match
that of the display, so that the displayed value can be used
without change in subsequent operations.

Single-variable statistics
Linear regression calculation
Quadratic regression calculation
Exponential regression calculation
Logarithmic regression calculation
Power regression calculation
Inverse regression calculation
The following statistics can be obtained for each statistical calculation (refer to the table below):
Linear regression calculation
Statistics of Q and W and, in addition, estimate of y for a given x
(estimate y´) and estimate of x for a given y (estimate x´)
Exponential regression, Logarithmic regression,
Power regression, and Inverse regression calculation
Statistics of Q and W. In addition, estimate of y for a given x and
estimate of x for a given y. (Since the calculator converts each
formula into a linear regression formula before actual calculation
takes place, it obtains all statistics, except coefficients a and b,
from converted data rather than entered data.)
Quadratic regression calculation
Statistics of Q and W and coefficients a, b, c in the quadratic
regression formula (y = a + bx + cx2). (For quadratic regression
calculations, no correlation coefficient (r) can be obtained.) When
there are two x´ values, press @≠.
When performing calculations using a, b and c, only one numeric
value can be held.
Q
Solver Function
The x value can be found that reduces an entered equation to “0”.
• This function uses Newton’s method to obtain an approximation. Depending on the function (e.g. periodic) or ‘Start’ value,
an error may occur (Error 2) due to there being no convergence
to the solution for the equation.
• The value obtained by this function may include a margin of
error. If it is larger than acceptable, recalculate the solution
after changing ‘Start’ and dx values.
• Change the ‘Start’ value (e.g. to a negative value) or dx value
(e.g. to a smaller value) if:
• no solution can be found (Error 2).
• more than two solutions appear to be possible (e.g. a cubic
equation).
• to improve the arithmetic precision.
• The calculation result is automatically stored in the X memory.
[Performing Solver function]
Q Press m0.
W Input a formula with an x variable.
E Press ∑0.
R Input ‘Start’ value and press ®. The default value is “0”.
T Input dx value (minute interval).
Y Press ®.
SIMULATION CALCULATION (ALGB)
If you have to find a value consecutively using the same formula,
such as plotting a curve line for 2x2 + 1, or finding the variable for
2x + 2y =14, once you enter the equation, all you have to do is to
specify the value for the variable in the formula.
Usable variables: A-F, M, X and Y
Unusable functions: Random function
• Simulation calculations can only be executed in the normal
mode.
• Calculation ending instructions other than = cannot be used.

• Data items exceeded 100 in the statistics mode.
In the statistical calculation formulas, an error will occur when:
• The absolute value of the intermediate result or calculation result
is equal to or greater than 1 × 10100.
• The denominator is zero.
• An attempt is made to take the square root of a negative number.
• No solution exists in the quadratic regression calculation.
Normal Probability Calculations
• P(t), Q(t), and R(t) will always take positive values, even when
t<0, because these functions follow the same principle used
when solving for an area.
Values for P(t), Q(t), and R(t) are given to six decimal places.
SIMULTANEOUS LINEAR EQUATIONS
Simultaneous linear equation with two unknowns (2-VLE) or with
three unknowns (3-VLE) may be solved using this function.
Q 2-VLE: m20
W 3-VLE: m21
• If the determinant D = 0, an error occurs.
• If the absolute value of an intermediate result or calculation result

Equation recall error (Error 5):
• The stored equation contains a function not available in the mode
used to recall the equation. For example, if a numerical value with
numbers other than 0 and 1 is stored as a decimal, etc., it cannot be
recalled when the calculator is set to binary.
• Make sure that the display appears as shown below. If the
display does not appear as shown, remove the batteries, reinstall them and check the display once again.

Automatic Power Off Function
This calculator will turn itself off to save battery power if no key is
pressed for approximately 10 minutes.

Memory over error (Error 6):
• Equation exceeded the formula memory buffer (256 characters in total
in F1 - F4).
Power source:
Calculation Ranges
Operating temperature:
External dimensions:
• Within the ranges specified, this calculator is accurate to ±1
of the least significant digit of the mantissa. However, a
calculation error increases in continuous calculations due
to accumulation of each calculation error. (This is the same
for yx, x¿ , ex, ln, etc., where continuous calculations are
performed internally.)
Additionally, a calculation error will accumulate and become
larger in the vicinity of inflection points and singular points
of functions.
• Calculation ranges
±10–99 ~ ±9.999999999×1099 and 0.
If the absolute value of an entry or a final or intermediate result of a
calculation is less than 10–99, the value is considered to be 0 in
calculations and in the display.

BATTERY REPLACEMENT
Notes on Battery Replacement
Improper handling of batteries can cause electrolyte leakage or
explosion. Be sure to observe the following handling rules:
• Replace both batteries at the same time.
• Do not mix new and old batteries.
• Make sure the new batteries are the correct type.
• When installing, orient each battery properly as indicated in the
calculator.
• Batteries are factory-installed before shipment, and may be exhausted before they reach the service life stated in the specifications.
Notes on erasure of memory contents
When the battery is replaced, the memory contents are erased.
Erasure can also occur if the calculator is defective or when it is
repaired. Make a note of all important memory contents in case
accidental erasure occurs.
When to Replace the Batteries
If the display has poor contrast or nothing appears on the display
even when ª is pressed in dim lighting, it is time to replace the
batteries.
Cautions
• Fluid from a leaking battery accidentally entering an eye could
result in serious injury. Should this occur, wash with clean water
and immediately consult a doctor.
• Should fluid from a leaking battery come in contact with your skin
or clothes, immediately wash with clean water.
• If the product is not to be used for some time, to avoid damage to
the unit from leaking batteries, remove them and store in a safe
place.
• Do not leave exhausted batteries inside the product.
• Do not fit partially used batteries, and be sure not to mix batteries
of different types.
• Keep batteries out of the reach of children.
• Exhausted batteries left in the calculator may leak and damage
the calculator.
• Explosion risk may be caused by incorrect handling.
• Do not throw batteries into a fire as they may explode.
Replacement Procedure
Turn the power off by pressing @ F.
Remove the two screws. (Fig. 1)
Slide the battery cover slightly and lift it to remove.
Remove the used batteries by prying them out with a ball-point
pen or other similar pointed device. (Fig. 2)
5. Install two new batteries. Make sure the “+” side is facing up.
6. Replace the cover and screws.
7. Press the RESET switch (on the back).
