The rounding function below by Charles is invalid (as it does not round negative numbers correctly)
and it does unnecessary/wrong input checking that does not work with some input.
This function is simple and rounds both negative and positive numbers:
<?php
/**
* Rounds number to specified precision.
* @param string $number
* @param integer $precision
* @see http://www.nanomvc.com/
* @return string
*/
public static function bcRound($number, $precision) {
return \bcadd($number, (\bccomp($number, "0") == -1? "-": "")
. "0." . \str_repeat("0", $precision) . "5", $precision);
}
?>
