# round

(PHP 3, PHP 4 )

round -- Rounds a float

## Description

float round ( float val [, int precision])

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.
