Description:
------------
PHP does an miscalculation,
ie. (584.04 / 2) / 3.14 is not same as 93 (that calculation returns 93)
Reproduce code:
---------------
<?
$a = 93;
$b = 93;
$c = 584.04;
$d = ($c / 2) / 3.14;
if ($a == $b) { echo "a and b matches!\n"; }
if ($d == $a) { echo "d and a matches!\n"; }
echo "a's value is $a AND d's value is $d";
?>
Expected result:
----------------
a and b matches!
d and a matches!
a's value is 93 AND d's value is 93
Actual result:
--------------
a and b matches!
a's value is 93 AND d's value is 93
