This article describes the formula syntax and usage of the FIXED function in Microsoft Excel.
Description
Rounds a number to the specified number of decimals, formats the number in decimal format using a period and commas, and returns the result as text.
Syntax
FIXED(number, [decimals], [no_commas])
The FIXED function syntax has the following arguments:

Number Required. The number you want to round and convert to text.

Decimals Optional. The number of digits to the right of the decimal point.

No_commas Optional. A logical value that, if TRUE, prevents FIXED from including commas in the returned text.
Remarks

Numbers in Microsoft Excel can never have more than 15 significant digits, but decimals can be as large as 127.

If decimals is negative, number is rounded to the left of the decimal point.

If you omit decimals, it is assumed to be 2.

If no_commas is FALSE or omitted, then the returned text includes commas as usual.

The major difference between formatting a cell containing a number by using a command (On the Home tab, in the Number group, click the arrow next to Number, and then click Number.) and formatting a number directly with the FIXED function is that FIXED converts its result to text. A number formatted with the Cells command is still a number.
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.
