DOLLAR function
This article describes the formula syntax and usage of the DOLLARfunction in Microsoft Excel.
Description
The function described in this Help topic converts a number to text format and applies a currency symbol. The name of the function (and the symbol that it applies) depends upon your language settings.
This function converts a number to text using currency format, with the decimals rounded to the specified place. The format used is $#,##0.00_);($#,##0.00).
Syntax
DOLLAR(number, [decimals])
The DOLLAR function syntax has the following arguments:

Number Required. A number, a reference to a cell containing a number, or a formula that evaluates to a number.

Decimals Optional. The number of digits to the right of the decimal point. If decimals is negative, number is rounded to the left of the decimal point. If you omit decimals, it is assumed to be 2.
Remark
The major difference between formatting a cell that contains a number by using a command (On the Home tab, in the Number group, click the arrow next to Number Format, and then click Number.) and formatting a number directly with the DOLLAR function is that DOLLAR converts its result to text. A number formatted with the Format Cells dialog box is still a number. You can continue to use numbers formatted with DOLLAR in formulas, because Microsoft Excel converts numbers entered as text values to numbers when it calculates.
Example
The example may be easier to understand if you copy it to a blank worksheet.
