See also bug #30069

This works fine with e.g. PHP 4.2.2 :)

Description:
------------
Strings that are between 0 and -1 and don't have a leading zero, e.g.
"-.2", "-.95", etc, do not get cast to floats.

This is a variant of bug 30069 which was closed with 4.3.9. That fix
did solve the problem for positive floats (".1", ".4", etc), but
apparently not for negative floats.

The bug is still present in CVS as of 11/8/04
(php4-STABLE-200411082130). I haven't checked the 5 branch yet, but my
guess is that it's wrong there too since 30069 also existed in the 5
branch.

Every past version of PHP has cast this properly (up through and
including 4.3.8).


Reproduce code:
---------------
echo '-.1' * 2;


Expected result:
----------------
-0.2

Actual result:
--------------
0
