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:

(“BIN” appears),

(“PEN” appears),

(“OCT” appears),

(“HEX” appears),

(“BIN”, “PEN”, “OCT”, and “HEX” disappear)

Note: The hexadecimal numbers A–F are entered by pressing

, and

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

Minute

Second

Coordinate Conversions

• Before performing a calculation, select the angular unit.

• The calculation result is automatically stored in the X and Y

memories (

in X memory, and

in Y memory).

• The results of coordinate conversions will be displayed as

decimal numbers even in the WriteView editor.
