PHP version: 5.2.7
PHP Bug Type: Math related
Bug description: Minus zero returned by simple multiplication of floating
numbers
Description:
------------
-0.1 * 0; // returns -0
I believe it should return 0 without the minus sign.

I will also submit another bug for the "BC math related" type.
echo bcadd("-0.0", "-0.0", 1); // returns -0.0
echo bccomp("-0.0", "0", 1); // returns -1
--
Reproduce code:
---------------
<?php
echo -0.1 * 0; // returns -0
?>
Expected result:
----------------
0
Actual result:
--------------
-0
