PHP doesn't handle strings like "12,300.2" correctly by default. See converting from strings. |
$foo = round(3.4); // $foo == 3.0 $foo = round(3.5); // $foo == 4.0 $foo = round(3.6); // $foo == 4.0 $foo = round(3.6, 0); // equivalent with above $foo = round(1.95583, 2); // $foo == 1.96 $foo = round(1241757, -3); // $foo == 1242000 |
Poznßmka: The precision parameter is only available in PHP 4.
