"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 … " - Bitmask highbit lowbit
