WebSimilarly to the bitwise OR operator, the arithmetic of XOR involves a sum. However, while the bitwise OR clamps values at one, the XOR operator wraps them around with a sum modulo two : Modulo is a function of two numbers—the dividend and the divisor —that performs a division and returns its remainder. WebNov 12, 2010 · The C ! operator is really just shorthand for != 0, so using it seems very close to cheating :).

Bitwise arithmetic

In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits. It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor. Most bitwise operations are … See more In the explanations below, any indication of a bit's position is counted from the right (least significant) side, advancing left. For example, the binary value 0001 (decimal 1) has zeroes at every position but the first (i.e., the rightmost) … See more The bit shifts are sometimes considered bitwise operations, because they treat a value as a series of bits rather than as a numerical quantity. In these operations, the digits are … See more Sometimes it is useful to simplify complex expressions made up of bitwise operations, for example when writing compilers.
