IF
Returns one of two values, depending on a test condition.
Syntax:
IF(test; value1; value2) where:
- test is or refers to a logical value or expression that returns a logical value (TRUE or FALSE).
- value1 is the value that is returned by the function if test yields TRUE.
- value2 is the value that is returned by the function if test yields FALSE.
If value2 is omitted it is assumed to be FALSE; if value1 is also omitted it is assumed to be TRUE.
Example:
IF(A1>5;100;"too small")
- returns the number 100 if A1 is greater than 5, and the text "too small" otherwise.
IF(1>2;"nonsense")
- returns FALSE - because value2 has been omitted and 1 is not greater than 2.
IF(2>1)
- returns TRUE - because both value1 and value2 have been omitted and 2 is more than 1.
