It would appear to be. If there is a function to print just to the digit could you point me in the direction? So I would want 0.20 0.14 0.16 0.08 respectively.

http://php.net/substring might do what you want. You'll have to calculate the decimal point for yourself and work from there. I use this function to add tax to a price.

Probably it will help you: function addtax($price,$tax) {

    bcscale(6);
    $calc = bcmul(bcdiv($price,100,6),bcadd(100,$tax,6),6);
    $output = bcadd (0,$calc,2);
    $roundarray = explode (".",$calc);
    if (substr($roundarray[1],2,1) >= 5)
	    {
	    	$output = $roundarray[0]+(substr($roundarray[1],0,2)/100)+0.01;
	    }
    else $output = $roundarray[0]+(substr($roundarray[1],0,2)/100)+0.0;
    return $output;
