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
1
3
(BASE) to input these
logical operators and functions.
All of the following examples are performed in the binary mode (
l
(BIN)).

Note:
In the case of a negative binary, octal or hexadecimal value, the
calculator converts the value to binary, takes the two’s complement, and
then converts back to the original number base. For decimal (base-10)
values, the calculator merely adds a minus sign.
Calculation Ranges, Number of Digits,
and Precision
The calculation range, number of digits used for internal calculation, and
calculation precision depend on the type of calculation you are performing.
