There was somone that posted about doing logarithms in dbpro. I threw together a plugin that allows you to do log,log2,and log10. I couldn't figure out logn. I'm just using the math.h library to do the math. If sombody could point me in the right direction for logn, that would be helpful.

Anyway, the dll is attached. Just put it in the plugins directory.

The commands are log,log2,and log10. I will make a keywords file later.

Enjoy!

p.s. This is my first dll, yay!

Edit: updated with help files and keywords. To install take the files in the zip and drag them into the folder where you installed dbpro.

I don't know anything about logarithems, I just knew some people were wanting it. I just used the math c++ library to do the math.

@Valle - As far as I know, and I do A-level maths, they are the same. By the way, off topic, I just noticed your sig and Wow! That was a great game!

@Coolgames - Could be useful. Not sure what for yet...

To do logn, it really is simple. So simple, in fact, that you don't even need the log2 or log10:

logn(x) = log(x)/log(n)

Simple... but keeping the log10 and log2 are a good idea, though.

To add the logn, just make it something like logn(base,x)
and in the dll use log(x)/log(n)

Never realized... DBp doesn't have logs. Cool.

Oh... and the difference between log and log 10 is that log probably does the natural logarithm, or ln (base e). Coolgames, you might want to rename log to ln and log10 to log.

(Sorry for the double post... but since I created a new account I can't edit my posts yet).
