Here is how to always round up...
$x = (a/b);
$r = round($x);
$d = ($x-$r);

if ($d>0){
$x = ($r+1);
}
.....

The result above will not always round up variable $x.
e.g If $x=0.6777
then $r = 1 and $d = -0.3223
Since $d < 0
$x is still 0.6777. It never round up ,except if $x < 0.5.
I believe ceil() is doing a good job.
