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).

Предостережение

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

Замечание: The precision parameter is only available in PHP 4.
