ISLOGICAL
Tests if a cell contains a logical value, TRUE or FALSE.
Syntax:
ISLOGICAL(value)
- Returns TRUE if value is either TRUE or FALSE, and FALSE otherwise.
Example:
ISLOGICAL(D5)
- where D5 contains FALSE, returns TRUE, because D5 contains a logical value.
ISLOGICAL(123)
- returns FALSE, because 123 is a number, not a logical value.
