User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5)

Description of problem:
When using %f with printf/sprintf etc on negative numbers,
it is emitting a NULL at the end for some reason.


printf("'%0.2f'\n", -10.45);

results in


(^@ being the NULL)

Positive numbers are fine.

It's not in php 4.2.2, or php 4.3.9

Wouldn't normally be an issue, as I would just run a later php.. but
customer is running Enterprise, and wants to stick to "standard" RHEL
issued rpm's for "support".

Yukky work arounds ensue.
