WebJul 22, 2015 · Bit masking allows you to use operations that work on bit-level. Editing particular bits in a byte (s) Checking if particular bit values are present or not. You actually apply a mask to a value, where in our case the value is our state 00000101 and the mask is again a binary number, which indicates the bits of interest. WebJan 30, 2024 · You should instead compute the 32 bit masks. uint32_t first = negone << lowbit; // all bits below lowbit are 0, others are 1 uint32_t last = negone << highbit << 1; … 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 … dallas hoopster for short
