Bit manipulation operations
WebAug 29, 2024 · A mask defines which bits you want to keep, and which bits you want to clear. Masking is the act of applying a mask to a value. This is accomplished by doing: Below is an example of extracting a subset of the bits in the value: Applying the mask to the value means that we want to clear the first (higher) 4 bits, and keep the last (lower) 4 bits. WebIn 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 presented as two-operand instructions where the …
