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 o (octal).

Converting a Calculation Result to another Type of
Value
You can use any one of the following key operations to convert the currently
displayed calculation result to another type of value:
V(DEC) (decimal),
(HEX) (hexadecimal), 5(BIN) (binary), 2(OCT)(octal).

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
(BASE) to input these
logical operators and functions.
All of the following examples are performed in the binary mode ( 5(BIN)).
