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.

Issues:

  • ISNUMBER(A1) where A1 is a logical value, returns TRUE. This behavior is not compatible with other competing spreadsheets.
    See Issue 58572;84266 .
