Integers support additional operations that make sense only for bit-strings. Bitwise operations only make sense for integers. Negative numbers are treated
Negative numbers are treated as their 2's complement value (this assumes a as their 2's complement value (this assumes a sufficiently large number of bits
sufficiently large number of bits that no overflow occurs during the operation). that no overflow occurs during the operation).
The priorities of the binary bitwise operations are all lower than the numeric The priorities of the binary bitwise operations are all lower than the numeric
operations and higher than the comparisons; the unary operation ``~`` has the operations and higher than the comparisons; the unary operation ``~`` has the
same priority as the other unary numeric operations (``+`` and ``-``). same priority as the other unary numeric operations (``+`` and ``-``).
This table lists the bit-string operations sorted in ascending priority This table lists the bitwise operations sorted in ascending priority
