Bug description: -Infinity value returned for long float nums
Description:
------------
Basically we're seeing long floats being given a string value of
-Infinity, even if we explicitly cast the variable. Python can handle
these vars no problem, don't see why PHP can't?
Thanks
Reproduce code:
---------------
<?php
$a = '6.48261999999999982691178956883959472179';
$c = (double) $a;
$b = sprintf("%0.2f", $c);
print $c.' '.$b;
?>
Expected result:
----------------
6.48261999999999982691178956883959472179 6.48
Actual result:
--------------
-Infinity -0N
