A bitwise operator treats its operands as a
{vector} of {bits} rather than a single number. {Boolean}
bitwise operators combine bit N of each operand using a
{Boolean} function ({NOT}, {AND}, {OR}, {XOR}) to produce bit
N of the result.

For example, a bitwise AND operator ("&" in {C}) would
evaluate 13 & 9 as (binary) 1101 & 1001 = 1001 = 9, whereas,
the logical AND, ({C} "&&") would evaluate 13 && 9 as TRUE &&
TRUE = TRUE = 1.

In some languages, e.g. {Acorn}'s {BASIC V}, the same operators
are used for both bitwise and logical operations. This
usually works except when applying NOT to a value x which is
neither 0 (false) nor -1 (true), in which case both x and (NOT
x) will be non-zero and thus treated as TRUE.

Other operations at the bit level, which are not normally
described as "bitwise" include shift and rotate.
