Returns the rounded value of val to specified precision (number of digits after the decimal point). precision can also be negative or zero (default).
| Caution |
PHP doesn't handle strings like "12,300.2" correctly by default. See converting from strings. |
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 |
Note: The precision parameter is only available in PHP 4.
