Description:
------------
when creating formulas, i encountered a strange bug:
this is the basic forumula:
ceil(user_hp * 1.1)

when user_hp = 100 you get the following formula

ceil(100*(110/100)) in my script.

this will result 111 instead of 110


Reproduce code:
---------------
<?php
$lol1 = ceil(100 * (110 / 100));
$lol2 = ceil(100 * 1.1);
$lol3 = ceil(110);
$lol4 = ceil(110.0);

echo $lol1;
?> 
<br />
<?php
echo $lol2;
?> 
<br />
<?php
echo $lol3;
?> 
<br />
<?php
echo $lol4;
?>

Expected result:
----------------
110
110
110
110


Actual result:
--------------
111
111
110
110
