I've modified functions that was originally written by "Alix Axel" - coppied from: http://stackoverflow.com/questions/1642614/how-to-ceil-floor-and-round-bcmath-numbers
Code:
<?php
/**
* Round fractions up
* BC MATH (Binary Calculator - numbers of any size and precision, represented as strings)
*
* @param string $number
* @return string
*/
function bcceil($number) {
$number = trim($number, '.0');
if (strpos($number, '.') !== false) {
if ($number[0] != '-') {
return bcadd($number, 1, 0);
}
return bcsub($number, 0, 0);
}
return $number;
}
/**
* Round fractions down
* BC MATH (Binary Calculator - numbers of any size and precision, represented as strings)
*
* @param string $number
* @return string
*/
function bcfloor($number) {
$number = trim($number, '.0');
if (strpos($number, '.') !== false) {
if ($number[0] != '-') {
return bcadd($number, 0, 0);
}
return bcsub($number, 1, 0);
}
return $number;
}
/**
* Rounds a bc-string-value half up
* BC MATH (Binary Calculator - numbers of any size and precision, represented as strings)
*
* @param string $number
* @param integer $precision (default:0)
* @return string
*/
function bcround($number, $precision = 0) {
$number = trim($number, '.0');
if (strpos($number, '.') !== false) {
if ($number[0] != '-') {
return bcadd($number, '0.' . str_repeat('0', $precision) . '5',
$precision);
}
return bcsub($number, '0.' . str_repeat('0', $precision) . '5',
$precision);
}
return $number;
}
?>
