How to calculate Pi to many places

September 20th, 2011 by Steven Pomeroy | Filed under Math Tricks.




Going through a recent search on Pi, I came across many pages that had listed values of Pi to many places.  For example, one page listed the value of Pi to 1000 places:

LOL – I have not confirmed this, but there is no reason for me to think that it is incorrect – or correct for that matter.

It turns out that there are many ways to determine Pi, and some of these methods are outlined here.  Has anybody used a method that they feel is better than others?

Sure, it is not a very useful exercise to calculate the value of Pi out to so many places, but it sure is cool!
