Description:
------------
When unserializing a previously serialized float that contains a exponent-expressed value (ie. 5Mrd), the result is wrong when locale is set to setlocale(LC_ALL,"de_DE");
(with compiled de-locales, of course)

With the locales set to "C", everything works fine.

In my opinion, this is a ',','.'-number-format-handling error.

Reproduce code:
---------------
setlocale (LC_ALL,"de_DE");

echo "test:".(float)3.14152;

$fl1=(float)5000000000; // 5Mrd
$str=serialize ($fl1);
$fl2=unserialize($str);

var_dump ($fl1);
var_dump ($fl2);
phpinfo();


Expected result:
----------------
test:3,14152
float(5.0E+9)
float(5.0E+9)


Actual result:
--------------
test:3,14152 (OK)
float(5.0E+9)
float(5) (hrmm, not quite!)
