How can I program a code to aproximate to the number pi?

Answer 1

In my example code I have shown how Madhava's algorithm is extremely precise and performing.
For example, with 20 computation cycles, the Leibniz (Euler) algorithm can not achieve a single byte precision, while Madhava can even reach a depth of 10 bytes!
Please see my code and comment if you wish..
