i need a bit of help with some maths.

I have a range 0 - 127 and i want to convert it into percentage.

So 0% = 0 and 100% = 127 and every number inbetween.

Generally, if you have numbers in the interval [a,b], to get the percentage inside your interval, the formula is:

percentage = 100 * (x-a) / (b-a)
