Interesting interpretation. This means that the
mapping between the
slider and the parameter will be
f(x) = k*a^x
with k=f(0) and a = f(1) if the slider goes form 0 to 1.
You probably meant a = f(1)/f(0).
Yes, thanks.
This also means
that it is illegal to include 0 in the parameter range.
In that case you can use f(x) = x*a^x, with a = f(1).
How do I invert this function? I am stuck.
What do you propose in the case of [-20.0, 40.0]?
