A BigInt can represent whole numbers larger than 2⁵³ - 1 (1).
📦 Node.js, 🌐 Web, 📜 Files, 📰 Docs, 📘 Wiki.

ES2020 introduced BigInt 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. To use it on the web, simply use the extra_bigint global variable after loading with a <script> tag from the jsDelivr CDN.

Stability: Experimental.
