Definable memories (D1–D4)
You can store functions or operations in defi nable memories
•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.
•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 definable 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 | 11 |
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 | 12 |
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 @:.

Operations | 13 |
Conversions can be performed between
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 B C D EF
K, m, A, l, i, and H.
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 | 14 |
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:

•Before performing a calculation, select the angular unit.
•The calculation result is automatically stored in the X and Y memories (r or x in X memory, and θ or y in Y memory).
•The results of coordinate conversions will be displayed as decimal numbers even in the WriteView editor.
