    A collection of functions for working with BigInts.
    📦 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 includes common bigint functions related to querying about numbers, comparing numbers, performing rounded division, performing modulo operations, controlling range of numbers, performing arithmetic operations, obtaining divisors of a number (and related operations), getting the number of possible arrangements of a set of objects, performing geometry-related calculations, performing basic statistical analysis, and finding various statistical 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
