bitwise |
1 definition found From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]: bitwiseA bitwise operator treats its operands as a {vector} of {bit}s 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. (1995-05-12)
