1. It is by design; the value range is either -128..127 or 0..255 2. You will see a number.
0 percent of 10 = 0
20 percent is a number whose value is between 0 and 1 so there is no way to represent it as a whole number.
If the value changes from fraction1 (F1) to fraction 2 (F2), then the percentage change is 100*(F2/F1 - 1) provided F1 > 0. If F1 is 0 then the value is not defined, and if F1 <0 you get nonsense results.
0 percent of 240000 = 0 (nothing)
