Calculating pi to an arbitrary number of digits

Here is a really usefull helper snippet that you can use to calculate PI to an arbitrary number of (string) digits. Because this is really usefull, this really usefull helper snippet is hosted on the really usefull github.

// This class calculates Pi. In Javascript. Main Features:
// 
// - calculate pi
// - to an arbitrary number of digits
// - it is functional code in that it functions well.
// - it is object oriented code in that it objects to very few things. 
// - it is procedural call in that it has a license that people proceed to ignore
// - it is overall a great and refreshing experience
//
// Example:
//
//  console.log(new CalculatePi(100).name);
