Pi Calculator 1.0

for Lenovo S860

This app allows you to calculate the digits of the irrational number pi (π) in real time. You can pick how many digits to calculate (up to 1 million). It lets you choose which algorithm to use (Chudnovsky with Binary Splitting, Machin using Euler Arctan, or Machin). Use this app for fun or as a benchmark tool. (On my test device, a Samsung Galaxy S3, it takes about 21 sec to calculate 1,000,000 digits using the Chudnovsky with Binary Splitting algorithm and takes another few seconds to render the display)
