This just uses a simple formula as shown in the project to calculate pi. The code is quite simple as well. There is a 7 digit limit of what it can calculate due to floating point arithmetic and there are a lot a iterations to reach that point. This was first spotted out to me by @meunspeakable. It is recommended to speed up the process in some way like using this link: https://turbowarp.org/771655539?turbo&fps=250.
