Equation Calculations - Casio fx-570EX User Manual

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: (DEC), (HEX),
(BIN), (OCT).

Logical and Negation Operations
Logical and negation operations are performed by pressing  and then
selecting the desired command (and, or, xor, xnor, Not, Neg) from the menu
that appears. All of the examples below are performed in the binary mode
((BIN)).
To determine the logical AND of 1010
To determine the bitwise complement of 1010
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 values, the
calculator merely adds a minus sign.
