meaning of bitwise

1. bitwise 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. Acorns BASIC V, the same operator 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.
