Results of Boolean Operations
When a Boolean expression is evaluated, the arguments are converted to hexadecimal
integers and the corresponding bits of the arguments are compared, as this table shows.

Both the argument and the

number ranges (page 66).
Rotate and shift operate on
16 base digits. To minimize
an overflow error, enter the
argument in binary form.
