One of the good iterative methods to calculate pi Warning Lag! Cycle = terms After 500 terms, 5 correct digits of pi slow&steady version @ https://scratch.mit.edu/projects/99140961/ if you get lag (1-2 fps)
Thanks to Gottfred Leibniz for giving us the formula! pi=4/1-4/3+4/5-4/7+4/9-4/11...=3.1415926535897 932384626433 832795028841971...
