Bug description: Float .25 as opposed to 0.25 calculates to 0
Description:
------------
Using PHP 5.0.1 as a CGI script.
10 * '.25' should be 2.5 but it equates to 0.
10 * floatval('.25') does equal 2.5.
Does not occur in PHP 5.0.0RC2.
May be a related to Bug # 29547.
Reproduce code:
---------------
$a = '.25';
$b = '0.25';
echo "10 * .25 == ".(10*$a)."\n";
echo "10 * 0.25 == ".(10*$b)."\n";
Expected result:
----------------
10 * .25 == 2.5
10 * 0.25 == 2.5
Actual result:
--------------
10 * .25 == 0
10 * 0.25 == 2.5
