You can store functions or operations in definable memories
(D1–D3).
• To store a function or operation, press x, followed by a definable
memory key (I, J, or K), followed by the operation you
want to store. Menu-related operations, such as J, cannot be
stored. Press j to return to the previous display.
• To call a stored function or operation, press the corresponding
memory key. Calling a stored function will do nothing if the
function that is called would be unusable in the current context.
• Any functions or operations that are stored in a definable memory
will be replaced when you save a new one into that memory.
• You cannot store functions or operations in definable memories
when entering values or items in STAT mode.

instructions.
Fraction Calculations
Arithmetic operations and memory calculations can be performed
using fractions. In NORMAL mode, conversion between a decimal
number and a fraction can be performed by pressing U.
6
Notes:
• Improper/proper fractions will be converted to and displayed as
decimal numbers if the number of digits used in their expression
is greater than nine. In the case of mixed fractions, the maximum
7
number of displayable digits (including integers) is eight.
• To convert a sexagesimal value to a fraction, first convert it by
pressing @ :.
Binary, Pental, Octal, Decimal, and Hexadecimal
Operations (N-base)
8
Conversions can be performed between N-base numbers in
NORMAL mode. 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.
Note: The hexadecimal numbers A–F are entered by pressing
9
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. In addition, 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 results of coordinate conversions will be displayed as
decimal numbers even in the WriteView editor.
Modify Function
Decimal calculation results are internally obtained in scientific
notation, with up to 14 digits in the mantissa. However, since
calculation results are displayed in the form designated by the
10
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 (@ n), the internal value is
11
converted to match that of the display, so that the displayed value
can be used without change in subsequent operations.
• When using the WriteView editor, if the calculation result is
displayed using fractions or irrational numbers, press U to
convert it to decimal form first.

another operation such as (+, –, ×, ÷), otherwise an error will
result.
• The quotient and remainder are shown in "NORM1" format.
If not all digits can be displayed in "NORM1" format, normal
division is performed.
Prime Factorization
In NORMAL mode, the calculation result can be shown as a
product of prime numbers.
• A positive integer greater than 2 and no more than 10 digits can
be factored into primes.
• A number that cannot be factored into a prime number with 3
digits or shorter is shown in parentheses.
• The calculation result of prime factorization is displayed
according to the editor setting (W-VIEW or LINE).
• The calculation result of prime factorization may extend off the
12
edges of the screen. You can see those parts by pressing l
or r. To jump to the left end or right end, press @ l
or @ r.
STATISTICAL CALCULATIONS
