Hi all,

Firstly first post wasn't sure where to put this apologies if it is wrong, and if this is a totally daft post.

I'm working on a little project for myself and I am having issues with the following:

I have three variables A B C.

A is a lower limit,

B is an upper limit

C is a ratio of the two.

Now I have got this far:

D=10^((C-A)/((B-A)/2))

This gives a % output where if C=A D=1, if B=C D=~100

What I am looking to do is have an output that is a ratio of A to B:

For example:

If A=C Ratio=0

If A=B Ratio= ∞

Hopefully that will make some sense?
