not
VALUE
not

The not operator reverses a boolean value.

Parameters

This operator has one parameter:

value – A Boolean (integer) value.

Description

The not operator reverses a Boolean value – true becomes false, false becomes true. Not is a unary operator, so there is no parameter on the left, only a single parameter on the right.

    not true() ☞ false
    not false() ☞ true
    not 1=1 ☞ false
    not "green"="blue" ☞ true

Note for C Programmers: The not operator is equivalent to the ~ operator in C. It actually performs a ones-complement on the value, so you can use this operator if you need to “flip the bits” in a numeric value.
