ISNUMBER
Tests if a cell contains a number.
Syntax:
ISNUMBER(value)
- Returns TRUE if value is a number or logical value and FALSE otherwise.
- ISNUMBER currently (OOo2.3) considers the logical values TRUE and FALSE as numbers. See Issues below.
Example:
ISNUMBER(123)
- returns TRUE.
ISNUMBER(“dog”)
- returns FALSE.
ISNUMBER(D5)
- where D5 contains 99, returns TRUE, because D5 contains a number.
