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).

13(BASE)c2(h) 10 +
13(BASE)c3(b) 10 +
13(BASE)c4(o) 10 = 36
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:
x(DEC) (decimal),
6(HEX) (hexadecimal), l(BIN) (binary), i(OCT)(octal).
To calculate 15

in the decimal mode, and then convert
the result to hexadecimal, binary, and octal
Ax(DEC) 15 * 37 = 555

i(OCT) 00000001053
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
13(BASE) to input these
logical operators and functions.
All of the following examples are performed in the binary mode (
l(BIN)).
To determine the logical AND of 1010
2
and 1100
2
(1010
2
and 1100
2
)
A 1010 13(BASE)1(and) 1100 = 0000000000001000
To determine the logical OR of 1011
2
and 11010
2
(1011
2
or 11010
2
)
A 1011 13(BASE)2(or) 11010 = 0000000000011011
