*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.

`const xbigint = require('extra-bigint');`

// import * as xbigint from "extra-bigint";

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

xbigint.isPrime(113n);

// โ true

xbigint.floorDiv(7n, 3n);

// โ 2n

xbigint.sqrt(81n);

// โ 9n

xbigint.lcm(2n, 3n, 4n);

// โ 12n

xbigint.log2(8n);

// โ 3n

xbigint.sum(1n, 2n, 3n, 4n);

// โ 10n

xbigint.mean(1n, 7n, 8n);

// โ 5n
