Here's what I have. Can you try building it into this plz?
Code:
Code:
function matheval($equation){
$equation = preg_replace("/pi/","3.14159265",$equation);
$equation = preg_replace("/e/","2.718281835",$equation);
$equation = preg_replace("/([^0-9]+)\^([^0-9]+)/","",$equation);
$equation = preg_replace("/[^0-9+\-.*\/()%]/","",$equation);
$equation = preg_replace("/([+-])([0-9]+)(%)/","*(1\$1.\$2)",$equation);
// you could use str_replace on this next line
// if you really, really want to fine-tune this equation
$equation = preg_replace("/([0-9]+)(%)/",".\$1",$equation);
if ( $equation == "" ) {
$return = 0;
} else {
eval("\$return=" . $equation . ";");
}
return $return;
}
