I agree to use a signed type. I also found it not so nice that the thermal
core does not support negative temperatures. I only chose unsigned long
because the patch got smallest that way, but I already expected this
answer ;)
We could also use int instead of long. INT_MAX °mC is still enough for using
a computer on the surface of the sun (Not for the center though)
