Bugs out with custom format and decimal input

Because of this odd logic here decimal number inputs will work when the value was less than the previous transition goal; otherwise it will show round(value - aria-valuemin). What?!

I'm going to sleep let me know if the issue isn't clear enough

as far as i remember there were some problems with decimal numbers because the value calculation is based on the width (in px). but i saw another bug (fixed in 0.8.1) which was a wrong calculation for valuemin != 0.

nonetheless i'm working on that to support decimal as well.
