Well if you needed negative values then you would use signed char.

You were expecting some sort of mystery of the universe? The difference is that signed types use half of the range for negative values. With unsigned types you have a wider positive range, and a guarantee of wrapping on overflow/underflow.

if you are trying to be really efficient with the amount of ram you are using and you need a variable that would hold anything from -10 to 10 then a singed char would work and you are only using 1 byte of memory.
