# — Bitwise NON EQUIVALENCE operator.

Description

The bitwise operators perform operations of bitwise AND, bitwise OR, bitwise NOT and bitwise non-equivalence.

The priority of these operators is less binding that the arithmetic ones, but more binding that the comparisons.

Parentheses may be used as above to force particular groupings.

Syntax

a # b  (bitwise NON EQUIVALENCE)

where the arguments a and b may be further expressions. They are converted to the nearest integer to machine precision and then the operation is performed.

Examples

Here is an example for the bitwise-group, comparing the different bitwise opcodes. It uses the file bitwise-group.csd.

Example 42. Example of the bitwise group.
