NUMBER_FORMAT(3)							 1							  NUMBER_FORMAT(3)

number_format - Format a number with grouped thousands

SYNOPSIS

       string number_format (float  $number, [int  $decimals])

DESCRIPTION

       string number_format (float  $number, int  $decimals, string  $dec_point = ".", string  $thousands_sep = ",")

	This function accepts 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 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.

PARAMETERS

	      o $number
		- The number being formatted.

	      o $decimals
		- Sets the number of decimal points.

	      o $dec_point
		- Sets the separator for the decimal point.

	      o $thousands_sep
		- Sets the thousands separator.

RETURN VALUES

	A formatted version of $number.

EXAMPLES

       Example #1

	      number_format(3) Example

	       For instance, French notation usually use two decimals, comma (',') as decimal separator, and space (' ')  as  thousand	separator.
	      This is achieved with this line :

	      <?php

	      $number = 1234.56;

	      // english notation (default)
	      $english_format_number = number_format($number);
	      // 1,235

	      // French notation
	      $nombre_format_francais = number_format($number, 2, ',', ' ');
	      // 1 234,56

	      $number = 1234.5678;

	      // english notation without thousands separator
	      $english_format_number = number_format($number, 2, '.', '');
	      // 1234.57

	      ?>
