# Not Operator

Negates an expression by inverting the bit values.

## Syntax:

    Result = Not Expression

## Parameters:

\<emph\>Result:\</emph\> Any numeric variable that contains the result of the negation.

\<emph\>Expression:\</emph\> 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.

## Example:

    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
