Fixed #152

I happen to like the '-0' format. My home-made weather app indicates if the temperature is below zero. If its -0.5 it would be rounded to -1, but -0 means between 0 and -0.5, so its still below zero.

@Flapper01 I'm curious, why is it necessary to know if it's between 0 and -0.5.
It seems odd to me to have '-0' displayed for a general user.
