Algorithms for pi using Python

Py-pi

Clculate pi to thousands of digits with Python

This project is aim to analye bunch of algorithms for thousands of digits of pi using Python. Also the main.py is able to test other algorithms if you like.

Example output

Time analyse

So far Gauss Legendre method wins.

Accurancy analyse

Basicly, every algorithm used output right answer.

Dependence

Python 2.7

Sagemath used for generate data figure

mpmath avaliable on pip: pip install mpmath used in reverse tan algo

Usage

clone the repo: git clone https://github.com/Page-David/PiPy.git

go into this directory: cd PiPy

Run the python script: ./main.sage [-h] [--max-time SECOND] [--step STEP] digits

./main.sage -h for more help.

FAQ

Why Python?

Some people asked why Python is used, why not a language able to compiled?

First of all, effiency and fast are quite different word. The aim of this project is to analyse different algorithms, but not to calculate more digits ASAP. Also, Python is more easier to get algorithms to work as there are many modules like mpmath.
