Press @ID@(BASE-N) to enter the BASE-N Mode when you want to
perform calculations using decimal, hexadecimal, binary, and/or octal
values. The initial default number mode when you enter the BASE-N Mode
is decimal, which means input and calculation results use the decimal
number format. Press one of the following keys to switch number modes:
~(DEC) for decimal, @(HEX) for hexadecimal, (§](BIN) for binary, or
I]!!)(OCT) for octal.

.
Use the following keys to input the letters A through F for hexadecimal
values: 8(A), 8(B), ffiii)(C), @(D), §J(E), G!i!)(F).
.
In the BASE-N
Mode, input of fractional (decimal) values and exponents is not supported. If
a calculation result has a fractional part, it is cut off.
.
The input and oulput
ranges is 16 bits for binary values, and 32 bits for other types of values. The
following shows details about input and output ranges.

Specifying the Number Mode of a Particular Input
Value
You can input a special command immediately following a value to specify
the number mode of that value. The special commands are: d (decimal), h
(hexadecimal), b (binary), and 0 (octal).

Converting a Calculation Result to another Type of
Value
You can use anyone of the following key operations to convert the currently
displayed calculation result to another type of value: ~(DEC)

Logical and Negation Operations
Your calculator provides you with logical operators (and, or, xor, xnor) and
functions (Not, Neg) for logical and negation operations on binary values.
. Use the menu that appears when you press

logical operators and functions.
All of the following examples are perfonned in the binary mode (~(BIN)).
