Rounding decimal points
<?php
function rfloor($real,$decimals = 2) {
return substr($real, 0,strrpos($real,'.',0) + (1 + $decimals));
}
function rceil($real,$decimals = 2) {
$newreal = substr($real, 0,strrpos($real,'.',0) + (1 + $decimals));
if($real[strlen($newreal)] > 0) {
$newreal[strlen($newreal) - 1] += 1;
}
return $newreal;
}
function rround($real,$decimals = 2,$halfdown = FALSE) {
$newreal = substr($real, 0,strrpos($real,'.',0) + (1 + $decimals));
if(($halfdown == FALSE) && ($real[strlen($newreal)] = 5)) {
$newreal[strlen($newreal) - 1] += 1;
}
else if($real[strlen($newreal)] > 5) {
$newreal[strlen($newreal) - 1] += 1;
}
return $newreal;
}
?>
Usage:
rceil(12.12146321,2); //12.13 -- as long as the value is greater than 0, round up.
rfloor(12.12946321,2); //12.12 -- drop everything after the number of decimal places
rround(12.12546321,2); //12.13 -- round half up
rround(12.12546321,2,TRUE); //12.12 -- round half down
