This function ccepts either one, two or four parameters (not three): If only one parameter is given, number will be formatted without decimals, but with a comma (",") between every group of thousands. If two parameters are given, number will be formatted with decimals with a dot (".") in front, and a comma (",") between every group of thousands. If all four parameters are given, number will be formatted with decimals decimals, dec_point instead of a dot (".") before the decimals and thousands_sep instead of a comma (",") between every group of thousands. This has a side effect that 1234.50 will display as: 1,234.50 Rick Widmer Internet Marketing Specialists www.developersdesk.com
