Name |  | ### ~ (bitwise one´s complement)
Examples |  |
    unsigned int value=4;  //   4 = 0000 0100

    value = ~ value;       // 251 = 1111 1011
Description |  | This operand is unary (requires one operand) and inverts bit by bit of an expression. Returns 0 for that position bit if the position is 1 or 1 if the position is 0. The following list shows all possible combinations: `~ 0 // Evaluates 1 ~ 1 // Evaluates 0`
Syntax |  |
    ~ expression
Parameters |  |
expression |  | any valid expression
Returns |  | One´s complement of an expression
