number_format

Synopsis

string number_format(double number[, int precision[, string decimal_separator,
                      string thousands_separator]])

Creates a string representation of number. If precision is given, the number is rounded to that many decimal places; the default is no decimal places, creating an integer. If decimal_separator and thousands_separator are provided, they are used as the decimal-place character and thousands separator, respectively. They default to the English locale versions (“.” and “,”). For example:

$number = 7123.456;
$english = number_format($number, 2); // 7,123.45
$francais = number_format($number, 2, ',', ' '); // 7 123,45
$deutsche = number_format($number, 2, ',', '.'); // 7.123,45

If rounding occurs, proper rounding is performed, which may not be what you expect (see round ).
