The function NOT returns the logical inverse of its argument.
This function accepts either the value TRUE or the value FALSE and returns the opposite value. If it is called with an argument of TRUE, it returns FALSE. When called with FALSE, it will return TRUE.
Declaration
NOT(input_boolean) -> logical_inverse
Parameters
- input_boolean (type: boolean)
- A boolean, either TRUE or FALSE.
Return Values
- logical_inverse (type: boolean)
- The logical inverse of input_boolean.
Examples
The most straightforward example of the NOT function is to call it with the literal values TRUE and FALSE.
NOT(TRUE) -> FALSE
NOT(FALSE) -> TRUE
Discussion
The function ISNOTEMPTY is very closely related to the NOT function. Rather than inverting a boolean expression, ISNOTEMPTY determines if a value has contents. For example, is a value the empty List ([]), the empty Object ({}), or the empty String ("").
