N function

Returns a value converted to a number.

Syntax

N(value)

Value     is the value you want converted. N converts values listed in the following table.

If value is or refers to

N returns

A number

That number

A date, in one of the built-in date formats available in Microsoft Excel

The serial number of that date

TRUE

1

FALSE

0

An error value, such as #DIV/0!

The error value

Anything else

0


Remarks

  • It is not generally necessary to use the N function in a formula, because Excel automatically converts values as necessary. This function is provided for compatibility with other spreadsheet programs.

  • Excel stores dates as sequential serial numbers so they can be used in calculations. By default, January 1, 1900 is serial number 1, and January 1, 2008 is serial number 39448 because it is 39,448 days after January 1, 1900. Excel for the Macintosh uses a different date system as its default.
