Bug description: Negative floats <1 as strings don't work in calculations
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
