Description:
------------
Mathenatical comparison of an expression with it's result returns false

When I try to compare 1.5 * 0.19 with it's result, 0.285, PHP returns false, but when i display the result 1.5 * 0.19 it echoes 0.285.

Reproduce code:
---------------
<?php
// BUG!!! This expression should return TRUE, because 1.5 * 0.19 is 0.285
echo ((1.5 * 0.19) == 0.285) ? "TRUE" : "FALSE";
echo "<br />"; echo "<br />";

// Mathematical representations are the same
echo sprintf("%e", 1.5 * 0.19);
echo "<br />"; echo "<br />";
echo sprintf("%e", 0.285);
echo "<br />"; echo "<br />";

// This expression is TRUE, that's correct
echo (0.285 == 0.285) ? "TRUE" : "FALSE";
echo "<br />";


?>

Expected result:
----------------
This expression should return TRUE, because 1.5 * 0.19 is 0.285


Actual result:
--------------
Actual result is FALSE
