This article describes the formula syntax and usage of the N function in Microsoft Excel.
Description
Returns a value converted to a number.
Syntax
N(value)
The N function syntax has the following arguments:
-
Value Required. 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! |

|
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.
Example
Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the column widths to see all the data.
