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.

WebThe usual way is to take a 1, and shift it left n bits. That will give you something like: 00100000.Then subtract one from that, which will clear the bit that's set, and set all the less significant bits, so in this case we'd get: 00011111. A mask is normally used with bitwise operations, especially and.You'd use the mask above to get the 5 least significant bits by …
