expression is greater than nine. In the case of mixed 
fractions, the maximum number of displayable digits 
(including integers) is eight.

•  If the number of digits in the denominator of a fractional 

result that uses 

π

 is greater than three, the result is 

converted to and displayed as a decimal number.

).

•  Equations that have one result require an additional eleven 

characters’ worth of memory to store in order to hold the result.

•  In addition to the amount of memory needed to store an 

equation, the WriteView editor will require a certain amount 
for the sake of display.

•  Equations also include calculation ending instructions, such 

as “

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 

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 

@

 

:

.

Binary, Pental, Octal, Decimal, and Hexadecimal 
Operations (N-base) 

13 

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 

K

A

m

B

A

C

l

D

i

E

, and 

H

F

.

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:

Degree

Minute

Second

Coordinate Conversions 

15

•  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.
