I don't know computer programming or mathematics.
All I want is a simple PHP code for the following natural logarithm.
ln((N+1)/X)
and then a code to convert the natural logarithm to a percentile, as below.
(1 - exp (-L) ) * 100
I would have thought this would have been quite simple, but my web developers can't seem to get right.
I need your help urgently, I am desperate to get my website up and running and these calculations are critical.
Any help you can provide would be greatly appreciated.
Thanks in advance for all your help.
Glen
