to calculate pi you need 55 blocks, 1 list*, and 3 variables (N being constant) *the pi list is only for output uses the spigot algorithm to calculate each digit of pi length of a ≈10N/3+1 algorithm complexity on an infinite scale is approx. O(N²) Due to Scratch's list length limit the most amount of digits that can be theoretically computed is 59,999. Check out my other math projects on my profile!
