Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same. Because of this, we hope you add your comments
to the existing bug instead.

Thank you for your interest in PHP.

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.
