Logical Boolean NOT Operator (FPScript)
Carries out a logical Boolean NOT operation for an expression.
Syntax
Not Expression
The syntax of the Not operator consists of the following elements:
Element |
Description |
|---|---|
Expression |
An expression that results in TRUE, FALSE or any numeric scalar value. For the numeric result, all values not equal to zero are taken to be TRUE. |
Remarks
If Expression returns a list, then the first element in the list is taken, as long as it is not also a list. Otherwise, the extraction process is repeated recursively. All other elements of the list are ignored.
The result is the logical negation of Expression.
If Expression is a quantity, then it has to have the SI dimension 1 and it will be transformed to the unit 1 before conversion.

Example
If Not HasVoidValues(Signal) Then ... End |
Carries out a block of code if the signal does not contain void values. |
Not 2 Pi |
Returns FALSE, since the unit Pi has the SI dimension 1 and 2 Pi transformed to the unit 1 results in the value 6.2831853, which is not equal to zero. |
