Random Numbers
A pseudo-random number with three significant digits can be gen-
erated by pressing @`=.
To generate the next random number, press =.
This function can be performed in the normal and statistics modes.
(This function is not supported under the N-Base function.)
•Random numbers use memory Y. Each random number is gen-
erated on the basis of the value stored in memory Y (pseudo-
random number series).
•To generate a new series of pseudo-random numbers, press
NOYto clear the memory Y.

Binary, Octal, Decimal, and Hexadecimal Operations
(N-Base)
This calculator can perform conversions between numbers ex-
pressed in binary, octal, decimal and hexadecimal systems. It can
also perform the four basic arithmetic operations, calculations with
parentheses and memory calculations using binary, octal, decimal,
and hexadecimal numbers. In addition, the calculator can carry out
the logical operations AND, OR, NOT, NEG, XOR and XNOR on
binary, octal and hexadecimal numbers.
Conversion to each system is performed by the following keys:
@ê:Converts to the binary system. “ ” appears.
@î:Converts to the octal system. “ ” appears.
@ì:Converts to the hexadecimal system. “ ” appears.
@í:Converts to the decimal system. “ ”, “ ”, and “ ”
disappear from the display.
Conversion is performed on the displayed value when these keys
are pressed.
Note: In this calculator, the hexadecimal numbers A – F are entered
by pressing Ñ, ⁄, É, é, ç, and ë,
and displayed as follows:
A →ï, B →∫, C →ó, D →ò, E →ô, F →ö
In the binary, octal, and hexadecimal systems, fractional parts
cannot be entered. When a decimal number having a fractional
part is converted into a binary, octal, or hexadecimal number, the
fractional part will be truncated. Likewise, when the result of a
binary, octal, or hexadecimal calculation includes a fractional part,
the fractional part will be truncated. In the binary, octal, and hexa-
decimal systems, negative numbers are displayed as a comple-
ment.

Calculations Using Physical Constants
A constant is recalled by pressing ßfollowed by the number of
the physical constant. Each physical constant must be specified
with a 2-digit number. For example, speed of light in a vacuum
should be designated as “01”.
The recalled constant appears in the display mode selected with
the designated number of decimal places.
Physical constants can be recalled in the normal mode (when not
set to binary, octal, or hexadecimal), 3-VLE mode, or statistics
mode.
Note: Physical constants and metric conversions are based either
on the 1986 values released by the Committee on Data for
Science and Technology (CODATA) of ICSU (International
Council of Scientific Unions) or on ISO specifications.

Modify Function
In this calculator, all calculation results are internally obtained in
scientific notation with up to 12 digits for the mantissa.
However, since calculation results are displayed in the form desig-
nated 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.

Binary, Octal, Decimal, and Hexadecimal Operations
(N-Base)
This calculator can perform conversions between numbers ex-
pressed in binary, octal, decimal and hexadecimal systems. It can
also perform the four basic arithmetic operations, calculations with
parentheses and memory calculations using binary, octal, decimal,
and hexadecimal numbers. In addition, the calculator can carry out
the logical operations AND, OR, NOT, NEG, XOR and XNOR on
binary, octal and hexadecimal numbers.
Conversion to each system is performed by the following keys:
@ê:Converts to the binary system. “ ” appears.
@î:Converts to the octal system. “ ” appears.
@ì:Converts to the hexadecimal system. “ ” appears.
@í:Converts to the decimal system. “ ”, “ ”, and “ ”
disappear from the display.
Conversion is performed on the displayed value when these keys
are pressed.
Note: In this calculator, the hexadecimal numbers A – F are entered
by pressing Ñ, ⁄, É, é, ç, and ë,
and displayed as follows:
A →ï, B →∫, C →ó, D →ò, E →ô, F →ö
In the binary, octal, and hexadecimal systems, fractional parts
cannot be entered. When a decimal number having a fractional
part is converted into a binary, octal, or hexadecimal number, the
fractional part will be truncated. Likewise, when the result of a
binary, octal, or hexadecimal calculation includes a fractional part,
the fractional part will be truncated. In the binary, octal, and hexa-
decimal systems, negative numbers are displayed as a comple-
ment.

Calculations Using Physical Constants
A constant is recalled by pressing ßfollowed by the number of
the physical constant. Each physical constant must be specified
with a 2-digit number. For example, speed of light in a vacuum
should be designated as “01”.
The recalled constant appears in the display mode selected with
the designated number of decimal places.
Physical constants can be recalled in the normal mode (when not
set to binary, octal, or hexadecimal), 3-VLE mode, or statistics
mode.
Note: Physical constants and metric conversions are based either
on the 1986 values released by the Committee on Data for
Science and Technology (CODATA) of ICSU (International
Council of Scientific Unions) or on ISO specifications.

Binary, Octal, Decimal, and Hexadecimal Operations
(N-Base)
This calculator can perform conversions between numbers ex-
pressed in binary, octal, decimal and hexadecimal systems. It can
also perform the four basic arithmetic operations, calculations with
parentheses and memory calculations using binary, octal, decimal,
and hexadecimal numbers. In addition, the calculator can carry out
the logical operations AND, OR, NOT, NEG, XOR and XNOR on
binary, octal and hexadecimal numbers.
Conversion to each system is performed by the following keys:
@ê:Converts to the binary system. “ ” appears.
@î:Converts to the octal system. “ ” appears.
@ì:Converts to the hexadecimal system. “ ” appears.
@í:Converts to the decimal system. “ ”, “ ”, and “ ”
disappear from the display.
Conversion is performed on the displayed value when these keys
are pressed.
Note: In this calculator, the hexadecimal numbers A – F are entered
by pressing Ñ, ⁄, É, é, ç, and ë,
and displayed as follows:
A →ï, B →∫, C →ó, D →ò, E →ô, F →ö
In the binary, octal, and hexadecimal systems, fractional parts
cannot be entered. When a decimal number having a fractional
part is converted into a binary, octal, or hexadecimal number, the
fractional part will be truncated. Likewise, when the result of a
binary, octal, or hexadecimal calculation includes a fractional part,
the fractional part will be truncated. In the binary, octal, and hexa-
decimal systems, negative numbers are displayed as a comple-
ment.

Calculations Using Physical Constants
A constant is recalled by pressing ßfollowed by the number of
the physical constant. Each physical constant must be specified
with a 2-digit number. For example, speed of light in a vacuum
should be designated as “01”.
The recalled constant appears in the display mode selected with
the designated number of decimal places.
Physical constants can be recalled in the normal mode (when not
set to binary, octal, or hexadecimal), 3-VLE mode, or statistics
mode.
Note: Physical constants and metric conversions are based either
on the 1986 values released by the Committee on Data for
Science and Technology (CODATA) of ICSU (International
Council of Scientific Unions) or on ISO specifications.

Binary, Octal, Decimal, and Hexadecimal Operations
(N-Base)
This calculator can perform conversions between numbers ex-
pressed in binary, octal, decimal and hexadecimal systems. It can
also perform the four basic arithmetic operations, calculations with
parentheses and memory calculations using binary, octal, decimal,
and hexadecimal numbers. In addition, the calculator can carry out
the logical operations AND, OR, NOT, NEG, XOR and XNOR on
binary, octal and hexadecimal numbers.
Conversion to each system is performed by the following keys:
@ê:Converts to the binary system. “ ” appears.
@î:Converts to the octal system. “ ” appears.
@ì:Converts to the hexadecimal system. “ ” appears.
@í:Converts to the decimal system. “ ”, “ ”, and “ ”
disappear from the display.
Conversion is performed on the displayed value when these keys
are pressed.
Note: In this calculator, the hexadecimal numbers A – F are entered
by pressing Ñ, ⁄, É, é, ç, and ë,
and displayed as follows:
A →ï, B →∫, C →ó, D →ò, E →ô, F →ö
In the binary, octal, and hexadecimal systems, fractional parts
cannot be entered. When a decimal number having a fractional
part is converted into a binary, octal, or hexadecimal number, the
fractional part will be truncated. Likewise, when the result of a
binary, octal, or hexadecimal calculation includes a fractional part,
the fractional part will be truncated. In the binary, octal, and hexa-
decimal systems, negative numbers are displayed as a comple-
ment.

Calculations Using Physical Constants
A constant is recalled by pressing ßfollowed by the number of
the physical constant. Each physical constant must be specified
with a 2-digit number. For example, speed of light in a vacuum
should be designated as “01”.
The recalled constant appears in the display mode selected with
the designated number of decimal places.
Physical constants can be recalled in the normal mode (when not
set to binary, octal, or hexadecimal), 3-VLE mode, or statistics
mode.
Note: Physical constants and metric conversions are based either
on the 1986 values released by the Committee on Data for
Science and Technology (CODATA) of ICSU (International
Council of Scientific Unions) or on ISO specifications.

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.
When to Replace the Batteries
If the display has poor contrast or nothing appears on the display
even when Nis pressed in dim lighting, it is time to replace the
batteries.
Caution
•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 into 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 batter-
ies 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.

Calculation Ranges
•Within the ranges specified below, this calculator is accu-
rate to ±1 in the least significant digit of the mantissa.
However, a calculation error increases in continuous calcu-
lations due to accumulation of each calculation error. (This
is the same for yx, x¿¿
¿¿
¿y, n!, ex, In, etc. where continuous
calculations are performed internally.)
Additionally, a calculation error will accumulate and be-
come larger in the vicinity of inflection points and singular
points of functions. (for example, calculating sinh xor tanh
xat x = 0)
•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.
Error Codes and Error Types
Syntax error (Error 1):
•An attempt was made to perform an invalid operation.
Ex. 2 +- 5 =
Calculation error (Error 2):
•The absolute value of an intermediate or final calculation result equals
or exceeds 10100.
•An attempt was made to divide by 0.
•The calculation ranges were exceeded while performing calculations.
Depth error (Error 3):
•The available number of buffers was exceeded. (There are 8 buffers*
for numeric values and 16 buffers for calculation instructions).
*4 buffers in STAT and the complex number mode.
Equation too long (Error 4):
•The equation exceeded its maximum input buffer (159 characters).
An equation must be shorter than 159 characters.

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 Nto clear the equation.
COMPLEX NUMBER CALCULATIONS
To carry out addition, subtraction, multiplication, and division using
complex numbers, press m1 to select the complex number
mode.

complex number stored in the independent memory (M) will be
cleared.
•Acomplex 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.

Calculation Ranges
•Within the ranges specified below, this calculator is accu-
rate to ±1 in the least significant digit of the mantissa.
However, a calculation error increases in continuous calcu-
lations due to accumulation of each calculation error. (This
is the same for yx, x¿¿
¿¿
¿y, n!, ex, In, etc. where continuous
calculations are performed internally.)
Additionally, a calculation error will accumulate and be-
come larger in the vicinity of inflection points and singular
points of functions. (for example, calculating sinh xor tanh
xat x = 0)
•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.
Error Codes and Error Types
Syntax error (Error 1):
•An attempt was made to perform an invalid operation.
Ex. 2 +- 5 =
Calculation error (Error 2):
•The absolute value of an intermediate or final calculation result equals
or exceeds 10100.
•An attempt was made to divide by 0.
•The calculation ranges were exceeded while performing calculations.
Depth error (Error 3):
•The available number of buffers was exceeded. (There are 8 buffers*
for numeric values and 16 buffers for calculation instructions).
*4 buffers in STAT and the complex number mode.
Equation too long (Error 4):
•The equation exceeded its maximum input buffer (159 characters).
An equation must be shorter than 159 characters.

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 Nto clear the equation.
COMPLEX NUMBER CALCULATIONS
To carry out addition, subtraction, multiplication, and division using
complex numbers, press m1 to select the complex number
mode.
There are two modes of expression of the results of complex
number calculations.
QRectangular coordinate mode. (xy appears on the display.)

•Upon changing to another mode, the imaginary portion of any
complex number stored in the independent memory (M) will be
cleared.
•Acomplex 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.

Calculation Ranges
•Within the ranges specified below, this calculator is accu-
rate to ±1 in the least significant digit of the mantissa.
However, a calculation error increases in continuous calcu-
lations due to accumulation of each calculation error. (This
is the same for yx, x¿¿
¿¿
¿y, n!, ex, In, etc. where continuous
calculations are performed internally.)
Additionally, a calculation error will accumulate and be-
come larger in the vicinity of inflection points and singular
points of functions. (for example, calculating sinh xor tanh
xat x = 0)
•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.
Error Codes and Error Types
Syntax error (Error 1):
•An attempt was made to perform an invalid operation.
Ex. 2 +- 5 =
Calculation error (Error 2):
•The absolute value of an intermediate or final calculation result equals
or exceeds 10100.
•An attempt was made to divide by 0.
•The calculation ranges were exceeded while performing calculations.
Depth error (Error 3):
•The available number of buffers was exceeded. (There are 8 buffers*
for numeric values and 16 buffers for calculation instructions).
*4 buffers in STAT and the complex number mode.
Equation too long (Error 4):
•The equation exceeded its maximum input buffer (159 characters).
An equation must be shorter than 159 characters.

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 Nto clear the equation.

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.
When to Replace the Batteries
If the display has poor contrast or nothing appears on the display
even when Nis pressed in dim lighting, it is time to replace the
batteries.
Caution
•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 into 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 batter-
ies 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.
