Using Boolean operators

The HP 49G provides a number of commands that enable you to perfonu

Boolean operations and comparisons on binary integers. These

commands—available by pressing 0 (B^ LOGIC—are illustrated in the

following table. The input syntax shown assumes that you are in algebraic

mode.

Commands

Examples

Input Output

AND Logical bit-by-bit

AND of two arguments.

Compares corresponding

bits and returns true (1) if

both bits are 1.

# 1100b AND# 1010b #1000b

NOT Returns the one’s

complement of the argu

ment. Each bit in the result

is the complement of the

corresponding bit in the

argument.

NOT (#11 lb)

#Liiiimoooob‘>

OR Logical bit-by-bit OR

of two arguments. Com

pares corresponding bits

and returns true (1) if either

bit is 1.

# 1100b OR# 1010b #lllOb

XOR Logical bit-by-bit

exclusive OR of two argu

ments. Compares coue-

sponding bits and returns

true (1) if only one of the

bits is 1.

# 1101b XOR# 1011b # IlOb

aThis answer assumes that the wordsize has been set to 12.
