WebThe bitwise NOT, or bitwise complement, is a unary operation that performs logical negation on each bit, forming the ones' complement of the given binary value. Bits that are 0 become 1, and those that are 1 become 0. For example: NOT 0111 (decimal 7) = 1000 (decimal 8) NOT 10101011 (decimal 171) = 01010100 (decimal 84) The result is equal to the two's … WebFor example, when shifting a 32 bit unsigned integer, a shift amount of 32 or higher would be undefined.
