¬ — Bitwise NOT operator.
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.
~ a (bitwise NOT)
where the argument a may be a further expression. It is converted to the nearest integer to machine precision and then the operation is performed.
Here is an example for the bitwise-group, comparing the different bitwise opcodes. Play bitwise-group.csd
