Converts a text string that represents a number to a number.
Syntax
VALUE(text)
Text is the text enclosed in quotation marks or a reference to a cell containing the text you want to convert.
Remarks
 Text can be in any of the constant number, date, or time formats recognized by Microsoft Excel. If text is not in one of these formats, VALUE returns the #VALUE! error value.
 You do not generally need to use the VALUE function in a formula because Excel automatically converts text to numbers as necessary. This function is provided for compatibility with other spreadsheet programs.
Example
The example may be easier to understand if you copy it to a blank worksheet.
