Defi nable memories (D1–D4)
You can store functions or operations in defi nable memories
(D1–D4).
• To store a function or operation, press x, followed by a
defi nable memory key (I, J, K, or L), 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 not work if the function
that is called would be unusable in the current context.
• Any functions or operations that are stored in a defi nable memory
will be replaced when you save a new one into that memory.
• You cannot store functions or operations in defi nable memories
when entering values or items in STAT, MATRIX, LIST, or
EQUATION modes, or into solver functions or simulation
calculations.
Chain Calculations
The previous calculation result can be used in the subsequent
calculation. However, it cannot be recalled after entering multiple
instructions or when the calculation result is in matrix/list format.
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.
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
number of displayable digits (including integers) is eight.
• To convert a sexagesimal value to a fraction, fi rst convert it by
pressing @ :.
Binary, Pental, Octal, Decimal, and Hexadecimal
Operations (N-base)
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.
Conversion to each system is performed with the following keys:
@ z ("BIN" appears), @ r ("PEN" appears),
@ g ("OCT" appears), @ h ("HEX" appears),
@ / ("BIN", "PEN", "OCT", and "HEX" disappear)
Note: The hexadecimal numbers A–F are entered by pressing
A B C
K , m , A , l
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
You can convert between decimal and sexagesimal numbers, and
from sexagesimal numbers to seconds or minutes. In addition,
the four basic arithmetic operations and memory calculations
can be performed using the sexagesimal system. Notation for
sexagesimal is as follows:
Degree
Coordinate Conversions
• Before performing a calculation, select the angular unit.
• The calculation result is automatically stored in the X and Y

memories ( or in X memory, and
• The results of coordinate conversions will be displayed as
decimal numbers even in the WriteView editor.

Physical Constants and Metric Conversions
Calculations using physical constants
To recall a constant, press K, then select a physical constant
from the list. (Each item is labeled with a 2-digit number.)
• To scroll up or down the list of constants, press u
(l) or d (r).
Use @ u (l) or @ d (r) to jump to the
fi rst or last page.
• Enter the fi rst digit of the 2-digit item number to jump to the
page containing the number that begins with that digit.
• When you enter the second digit, the constant is displayed
automatically according to the display and decimal
placement settings.
• Physical constants can be recalled in NORMAL (excluding
N-base), STAT, CPLX, MATRIX, LIST, and EQUATION modes.
• The following table lists the physical constants. See the
calculation example sheet for physical constant symbols
11
and units.
Note: Physical constants and metric conversions are based
on the 2006 CODATA recommended values, or on
the 1995 Edition of the "Guide for the Use of the
International System of Units (SI)" released by NIST
12
(National Institute of Standards and Technology).

Metric conversions
Enter a value to be converted, then press @ L, and
select a metric conversion by entering its 2-digit number.
• The metric conversion list is used in the same manner as
the list of physical constants.
• Unit conversions can be performed in NORMAL (excluding
14
N-base), STAT, MATRIX, LIST, and EQUATION modes.
• The following table lists units used in metric conversion.
See the calculation example sheet for the metric
conversion reference table.
