nodef/extra-bigint: A collection of functions for working with BigInts

A collection of functions for working with BigInts.<br> 📦 Node.js, 🌐 Web, 📜 Files, 📰 Docs, 📘 Wiki.

A BigInt can represent whole numbers larger than 2⁵³ - 1 (1). ES2020 introduced it as a built-in object. BigInt enables us to represent integers with arbitrary precision, allowing us to perform mathematical operations on large integers (2). This package provides operations to work with sign, perform arithmetic operations such as division and modulo, finding roots, working with factors, finding logarithm, and performing basic statistics including a number of means.

This package is available in Node.js and Web formats. The web format is exposed as extra_bigint standalone variable and can be loaded from jsDelivr CDN.

Stability: Experimental.

const bigint = require('extra-bigint');
// import * as bigint from "extra-bigint";
// import * as bigint from "https://unpkg.com/extra-bigint/index.mjs"; (deno)

bigint.isPrime(113n);
// → true

bigint.floorDiv(7n, 3n);
// → 2n

bigint.sqrt(81n);
// → 9n

bigint.lcm(2n, 3n, 4n);
// → 12n

bigint.log2(8n);
// → 3n

bigint.sum(1n, 2n, 3n, 4n);
// → 10n

bigint.mean(1n, 7n, 8n);
// → 5n
