Pi-in-Py
By Chris Morris.
A simple little Python application to approximate pi using various methods.
Running the App
Simply run in IDLE or open Terminal and run "python pi.py" inside the directory where pi.py is stored. Terminal is recommended for the best experience.
Requires Python 3.x.
###Please note that:
- This app can slow down your computer considerably as well as drain your battery. Please save all work prior to running the application, and always start with a small number of iterations (try 100).
- You can exit the app by using ctrl+C at any time.
Background
This app was simply created as a way for me to visualise how different methods work when approximating pi, and to also calculate the convergence times. It was also a good excuse to practice some Python!
Please feel free to fork and add other methods for calculating pi.
