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. … See more Bitwise operations are necessary particularly in lower-level programming such as device drivers, low-level graphics, communications protocol packet assembly, and … See more • Arithmetic logic unit • Bit manipulation • Bitboard See more • popcount, used in cryptography • count leading zeros See more Sometimes it is useful to simplify complex expressions made up of bitwise operations, for example when writing compilers.

WebIn computer science, a mask or bitmask is data that is used for bitwise operations, particularly in a bit field.Using a mask, multiple bits in a byte, nibble, word, etc. can be set either on or off, or inverted from on to off (or vice versa) in a single bitwise operation.An additional use of masking involves predication in vector processing, where the bitmask is … WebBitwise AND takes bit representations of its two operands, combines bits in pairs by their order, and applies logical AND to each pair. It returns the resulting bit sequence converted back to its decimal form. For each bit pair, Bitwise AND returns 1 only if both bits are 1. In all other cases, it returns 0. 19款英朗空调滤芯
