Not Operator

Negates an expression by inverting the bit values.


Result = Not Expression


Result: Any numeric variable that contains the result of the negation.

Expression: Any expression that you want to negate.

When a Boolean expression is negated, the value True changes to False, and the value False changes to True.

In a bitwise negation each individual bit is inverted.


Sub ExampleNot
Dim vA As Variant, vB As Variant, vC As Variant, vD As Variant
Dim vOut As Variant
    vA = 10: vB = 8: vC = 6: vD = Null
    vOut = Not vA REM Returns -11
    vOut = Not(vC > vD) REM Returns -1
    vOut = Not(vB > vA) REM Returns -1
    vOut = Not(vA > vB) REM Returns 0
End Sub
