need help with pi calculations!

daven1 · 01-06-2005, 06:24 PM

Its been a while sence ive used any unix system, and im wondering if i could get some help from someone with more exp. than me. I woudnt think this would be a complicated program to make for someone with exp.

I need a program that can calculate pi, but is unrestricted. Ive tried a few and there generally limited to 9m or so, i need something that can go as long as i need it too. If anyone could cook up something or tell me where to find such a program i would really appreciate it!

Thanks,
Daven

use this formula to calculate pi

4* (Sigma(from k=0 to n) of ((-1)^(K+1))/(2K-1)

as you increase n you increase your accuracy

That equation may be to slow now that i think about it. You will need to have n = around 300 inorder to get two digits of accuracy.

you may want to try this.

pi = sqrt(6* (Sigma (from k = 1 to n) of 1/(n^2)))
likewise as n increases so does accuracy
