[removed] PI (π) Calculator

Question

Is there a way to calculate pi in Javascript? I know there you can use Math.PI to find pie like this:

var pie = Math.PI;
alert(pie); // output \"3.1         


        

Answer 1

Here is my implementation using Infinite Series

function calculatePI(iterations = 10000){
    let pi = 0;
    let iterator = sequence();

    for(let i = 0; i < iterations; i++){
        pi += 4 /  iterator.next().value;
        pi -= 4 / iterator.next().value;
    }

    function* sequence() {
      let i = 1;
      while(true){
        yield i;
        i += 2;
      }
    }

    return pi;
}
