[Random Dice]
To simulate a die-rolling, a random integer between 1 and 6 can be
generated by pressing @`1®.
[Random Coin]
To simulate a coin flip, 0 (head) or 1 (tail) can be randomly gener-
ated by pressing @`2®.
[Random Integer]
An integer between 0 and 99 can be generated randomly by press-
ing @`3®.
Angular Unit Conversions
Each time
@g

[Temporary memories (A-F, X and Y)]
Press O and a variable key to store a value in memory.
Press R and a variable key to recall a value from the memory.
To place a variable in an equation, press K and a variable key.
[Independent memory (M)]
In addition to all the features of temporary memories, a value can
be added to or subtracted from an existing memory value.
Press ªOM to clear the independent memory (M).
[Last answer memory (ANS)]
The calculation result obtained by pressing = or any other
calculation ending instruction is automatically stored in the last
answer memory.
Note:
• Calculation results from the functions indicated below are auto-
matically stored in memories X or Y replacing existing values.
• Random function ...... Y memory
• →rθ, →xy .................... X memory (r or x), Y memory (θ or y)
• Use of R or K will recall the value stored in memory using
up to 14 digits.
Chain Calculations
• The previous calculation result can be used in the subsequent
calculation. However, it cannot be recalled after entering multiple
instructions.
• When using postfix functions (¿ , sin, etc.), a chain calculation is
possible even if the previous calculation result is cleared by the
use of the ª key.
Fraction Calculations
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 frac-
tional 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 dis-
played 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:
Coordinate Conversions
• Before performing a calculation, select the angular unit.
• The calculation result is automatically stored in memories X
and Y.
• Value of r or x: X memory • Value of θ or y: Y memory
Calculations Using Physical Constants
See the quick reference card and the English manual reverse side.
A constant is recalled by pressing ß followed by the number
of the physical constant designated by a 2-digit number.
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, pental, octal, or hexadecimal), or statistics mode.
Note: Physical constants and metric conversions are based either
on the 2002 CODATA recommended values or 1995 Edi-
tion of the “Guide for the Use of the International System of
Units (SI)” released by NIST (National Institute of Stand-
ards and Technology) or on ISO specifications.
Metric Conversions
See the quick reference card and the English manual reverse side.
Unit conversions can be performed in the normal mode (when not
set to binary, pental, octal, or hexadecimal), and statistics modes.
