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
N O Y to clear the memory Y.

INITIAL SETUP
Mode Selection
Normal mode: m0
Used to perform arithmetic operations and function calculations.
The pointer “Æ” appears below “0: NORMAL”.
Complex number mode: m1
Used to perform arithmetic operations with complex numbers.
The pointer “Æ” appears below “1: CPLX”.

=14, simply specify a new value for each variable in the formula.
Usable variables: A-D, M, X and Y
Unusable functions: RANDOM
Simulation calculations can only be executed in the normal mode.
Calculation ending instructions (%, etc.) other than = cannot
be used.
Performing Calculations
Q Press m0.
W Enter a formula with at least one variable.
E Press @≤.
R Variable input screen will appear. Enter 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. Entry of
formulas are not permitted.
Upon completing the calculation, press @≤ to perform
calculations using the same formula.
Variables and numerical values stored in the memories will be
displayed in the variable input screen. To change a numerical
value, enter the new value and press ®.
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:
: Converts to the binary system. “
” appears.
: Converts to the octal system. “
” appears.
: Converts to the hexadecimal system. “
” appears.
: 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 ß followed 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.
