Formulas and functions > Functions from A to Z > ISNUMBERP (Calculate 97 compatibility function)

Syntax:

ISNUMBERP(Cell)

Description:

This returns TRUE if the specified value is a number or a logical value.

Dates are also considered as numbers.

Note:

This function was retained only for compatibility with Calculate 97. If possible, use the Excel-compatible function ISTNUMBER (without "P") instead of this function.

The difference:

ISNUMBERP treats logical values as numbers, whereas ISNUMBER does not.

Compatibility notes:

This function does not exist in Microsoft Excel. If you save a document in Excel format, all calculations using this function will be replaced with their current result as a fixed value.

Example:

If the cells A1 to A4 contain the values:

"Text", 42, 09/25/2018 and TRUE

the following applies:

ISNUMBERP(A1) returns FALSE

ISNUMBERP(A2) returns TRUE

ISNUMBERP(A3) returns TRUE

ISNUMBERP(A4) returns TRUE (!)

For comparison: ISNUMBER(A4) returns FALSE
