Natural logarithm Ranking System

[Glen kzg]

Hi, I'm really sorry but I know nothing of Computer programming or mathematics.
Could someone please give me the code for the natural logarithm
ln((N+1)/X)

and then a code to convert these natural logarithms back into percentiles
(1 - exp (-L) ) * 100

My web designers don't seem to be able to get these to work properly, any help would be greatly appreciated, I need this desperately. Thanks.

Ehhhh.... I think we have a policy against giving out free code to corporations... . What have your designers/developers researched?

If you are willing to post some of the code, we would be willing to help find the issue.

Google for 'PHP natural logarith'
It will direct you to the manuals of PHP

If your web designers are not able to do that, than you should fire them!

BTW, the link to the docs is: http://php.net/manual/en/function.log.php

@Luuk that was my point, but didn't want to just give him the cold shoulder.
I think his designers either really are that bad or didn't research and he just wanted free code.

If his designers are not smart enough to search for a solution on the web, than they probably are not smart enough to understand the information on the link I gave....

;)

This is actually a good note in the Career section.
Resumes might sound good, but the truth will come out in the end.....
