Two infrequent binary operators are the ~ (or 1's complement) and the ! (or NOT).
The 1's complement operator flips all the bits in a value, turning a 1 into a 0 and a 0 into a 1. For example:
~01010011 = 10101100
The ! (NOT) operator affects the entire value - all the bits. It changes any nonzero value to 0, and the value 0 to 1:
!01010011 = 00000000 !00000000 = 00000001
Zero and 1 are the only two results possible when using the bitwise ! operator.
Both the ~ and ! operators are unary operators.
