(PHP 3, PHP 4 )

(number of digits after the decimal point). precision can
also be negative or zero (default).
Example 1. round() examples
<?php
echo round(3.4); // 3
echo round(3.5); // 4
echo round(3.6); // 4
echo round(3.6, 0); // 4
echo round(1.95583, 2); // 1.96
echo round(1241757, -3); // 1242000
echo round(5.045, 2); // 5.05
echo round(5.055, 2); // 5.06
?>
Note: PHP doesn't handle strings like "12,300.2"
correctly by default. See converting from strings.
Note: The precision parameter is only available in PHP
4.
