Could someone please explain me how it works?

Manual says

[Quote]unlerp(a, b, y) Reverse linear interpolation: if lerp(a, b, x) = y, then unlerp(a, b, y) = x. Calculates (y - a) / (b - a).[/QUOTE]

but to be fair i don't get it.

One possible use of unlerp is to do scrollbar math.

In layman's terms, it gives you the percentage of point between two values.

You have points A and B and you want to know where your "x" between points is in relation to those points. So you do unlerp(A,B,x) to see where the x is standing relative to the range between A and B.
