Bug description:  strval gives :.0E-7 for 1e-6

Description:
------------
When converting a number in exponential format with negative exponent of
n=6,7,... strval (or implicit conversion to string) gives :.0E-(n+1) if
there is no fractional part present. The error can be found both in the
precompiled PHP 5.2.4 and self-compiled 5.2.6, but it cannot be reproduced
under Windows or under PHP 5.2.3 Ubuntu 7.10 (64bit). Seems to be closely
related to OS (?).

Reproduce code:
---------------
$float=1e-6;
echo strval($float);

Expected result:
----------------
1e-6 or 1.0e-6

Actual result:
--------------
:.0E-7
