Using Boolean Operators
The following table contains commands from the MTH BASE LOGIC
menu
(fMTH

that perform Boolean operations
on binary integers. Unless otherwise stated, each example assumes the
wordsize is set to 24.

AND Logical bit-by-bit
AND of two arguments.
L“ w 11BBb

NOT Returns the
one’s complement of the
argument. Each bit in the
result is the complement of
the corresponding bit in the
argument.
