I have found one more problem:
I'm getting following:
bash -c 'printf "x%+fx\n" -0'
x+0.000000x
where it should be:
x-0.000000x
This is cause by:
/* round off to the precision */
#define ROUND(d, p) \
(d < 0.) ? \
d - pow_10(-(p)->precision) * 0.5 : \
d + pow_10(-(p)->precision) * 0.5
where (-0 < 0.) isn't true.
And there is probably no easy solution for this:

Fixed in chunk #3 (but the problem is there also for other types!).
My fix breaks following case:
Thanks, the patches are very helpful.
