Syntax

NOT(logical)


Arguments

logical

A value or expression that can be evaluated as TRUE or FALSE.



Examples

Example 1

=NOT(OR(84>=100,78>=100))
formula evaluates each test case, and returns TRUE in this example, since the OR function returns TRUE.

NOT-1

Example 2

=IF(OR(NOT(“FIRE, FLYING”=”Water”),”I”=”II”,AVERAGE({78,84,78,109,85,100})>=100),”Pass”,”Fail”)
returns Pass because the first test (NOT(“FIRE, FLYING”=”Water”)) returns TRUE. Although the two strings being compared are not the same, the NOT formula reverts the result of the logical statement.
