Not

Logical Not turns True values to False, and vice versa. NOT is usually denoted by the symbol ¬. The value \( \neg x \) is True if \( x \) is False and it is False if \( x \) is True. Its table is simple.

    ¬| 
  ---+----
    0|  1
    1|  0

NOT applied to a byte is applied bit by bit.

Example

Here is the logical negation of a byte.

    ¬ 01100100
  ------------
      10011011
