Description:
------------
the result for $a is 40 exactly.
you can check it but i donk know why the if choosed that it is different. the problem is with the result that this take from the equation. if you print the result this show 40 but if you compare this with 40 say that is different

thanks for all


Reproduce code:
---------------
<?
$a=((1899-1139.4)*100)/1899;
if($a==40)
echo "is good $a";
else
echo"is bad $a";
?>

Expected result:
----------------
is good 40

Actual result:
--------------
is bad 40
