I took a look at your code and was overwhelmed at not being able to understand most of it. Honestly that is the most difficult code to follow as I've ever come across, no offense cause I still don't really understand all that much the way it is. Like for example:
   L= sum<j=0..N-1>( r^j )
    L= 1+r+..+r^(N-1)
    r*L - L = r*( 1+r+..+r^(N-2)+r^(N-1) ) - ( 1+r+..+r^(N-1) )
    r*L - L = ( r+r^2+..+r^(N-1)+r^N ) - ( 1+r+..+r^(N-1) )
    r*L - L = r+r^2+..+r^(N-1) + r^N - ( 1 + r+..+r^(N-1) )
    r*L - L = r+r^2+..+r^(N-1) + r^N - 1 - ( r+..+r^(N-1) )

Holy cow, it looks like I opened a binary file in notepad :) You're saying your script is more accurate than mine but is my equation and everything suffient anyways? This wasn't meant to be dead accurate, just to help my girlfriend with her homework.

Thanks!
