Calculate PI Digits with P5.JS / JavaScript - Looking for maximum efficiency

Hi, I am working on a project in [login to view URL] /JavaScript and I need the ability to calculate PI digits starting at the beginning and going for as long as possible. Currently, I am using the Spigot Algorithm that can be found here: [login to view URL] This code works but after a day of it running non-stop it begins to slow down because it takes more and more CPU calculations to generate the next digit of PI(I believe), and this in turn slows the [login to view URL] program that is using the digits of PI. I believe BigInt is part of the reason it gets slower as time goes on. So, I'm looking for a more efficient way to generator each digit of PI and I've heard there are two major ways to do this: one is CPU intensive and the second is more memory intensive? If this is true, I would like a method that is more memory intensive because the [login to view URL] program needs CPU power to run well; and memory is more abundant on PC these days, but of course if the PI generator uses all the PC's RAM in a day, that's not a better solution than I currently have. Is there a memory intensive way to generate PI? Is it as good as or better than the Spigot Algorithm If not, is there a better way to generate PI other than the Spigot Algorithm? If so will this method run longer, before there is noticeable speed loss? I want to be able to generate PI for as long as possible with as little CPU loss a possible. Here is the [login to view URL] code I have that uses the Spigot Algorithm: let piBuffer; function setup() { createCanvas(400, 400); piBuffer = new PiBuffer(); [login to view URL](0); frameRate(30); } function draw() { print('NextPiDigit = ' + [login to view URL]()); } class PiBuffer { constructor() { this.q = BigInt(1); this.r = BigInt(180); this.t = BigInt(60); this.i = BigInt(2); // y is the previous digit this.y this.u [login to view URL] = []; } // Caluculate the next numDigits of Pi async calculatePi(loopDelay) { while(true){ await new Promise(resolve => { setTimeout(() => { resolve(true); [login to view URL]([login to view URL]()); }, loopDelay); }); } } calculateNextPiDigit() { // Spigot Method of calculating Pi this.y = (this.q*(BigInt(27)*this.i-BigInt(12))+BigInt(5)*this.r)/(BigInt(5)*this.t); this.u = BigInt(3)*(BigInt(3)*this.i+BigInt(1))*(BigInt(3)*this.i+BigInt(2)); this.r = BigInt(10)*this.u*(this.q*(BigInt(5)*this.i-BigInt(2))+this.r-this.y*this.t); this.q = BigInt(10)*this.q*this.i*(BigInt(2)*this.i-BigInt(1)); this.t = this.t*this.u; this.i = this.i+BigInt(1); if (this.i % BigInt(1000) === BigInt(0)){ print("Current Digit=" + this.i); } return this.y } getNextPiDigit() { return [login to view URL](); } }
