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 … WebbitMask(highbit, lowbit) Generate a mask consisting of all 1’s between low-bit and highbit. 3 16 Table 1: Bit-Level Manipulation Functions. 4.2 Two’s Complement Arithmetic Table 2 describes a set of functions that make use of the two’s complement representation of integers.
