If it's a 1, it's changed to a 0, if it's a 0, it's changed to a 1. The bit wise NOT has the same effect as XOR'ing a value against the max value for a specific type:
WebThe bitwise NOT, or bitwise complement, is a unary operationthat performs logical negationon each bit, forming the ones' complementof the given binary value. Bits that are 0 become 1, and those that are 1 become 0. NOT 0111 (decimal 7) = 1000 (decimal 8) NOT 10101011 (decimal 171)
