pi is a Python script that computes each digit of the value of pi. As long as this script runs it continues to generate digits. As a matter of full disclosure, I did not write this. I am posting it here as a means of preserving the algorithm and making it available to others.

pi.py

import sys

def calcPi():
    q, r, t, k, n, l = 1, 0, 1, 1, 3, 3
    while True:
        if 4*q+r-t < n*t:
            yield n
            nr = 10*(r-n*t)
            n  = ((10*(3*q+r))//t)-10*n
            q  *= 10
            r  = nr
        else:
            nr = (2*q+r)*l
            nn = (q*(7*k)+2+(r*l))//(t*l)
            q  *= k
            t  *= l
            l  += 2
            k += 1
            n  = nn
            r  = nr
 
pi_digits = calcPi()
i = 0
for d in pi_digits:
    sys.stdout.write(str(d))
    i += 1
    if i == 50:
        print("")
        i = 0
        

Wow! Thanks for this.

holly crap that took way to long to find one that works thanks!

Perfect! Thanks

I ran it in repl.it, and it definitely works!

how

Hi, Can you elaborate on what you mean by “how”? How to use repl.it? How to use this script? How to get it to execute?

how does this even work
