Details

This operator is especially useful for calculations on pseudo-boolean control signals. Pseudo-boolen signal values are values that are defined to be boolean False if they are 0, and boolean True if they are greater than or equal to 1. If boolean values are defined this way, a logical AND operation equals multiplication, and a logical OR operation equals addition. The operator described here (1 - S) then equals a logical Inverter (True becomes False, and False becomes True).

Of course, this operator can also be used in other situations, and is not limited to do calculations on pseudo-booleans.
