SoftSeven Pi calculates Pi (π) using the formula Pi (π) = 4*(1/1 - 1/3 + 1/5 - 1/7 + 1/9...)
It also shows how using averages of the last two iterations of the formula will give a closer approximation of Pi (π).
Finally it uses averages of the averages with even closer approximation of Pi (π) with the same number of calculations!
