Readme

This package includes some common statistics functions.
📦 Node.js, 🌐 Web, 📜 Files, 📰 JSDoc, 📘 Wiki.

Mathematics is the classification and study of all possible patterns. (1)

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

Stability: Experimental.


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

math.sum(1, 2, 3, 4);
// 10

math.median(1, 7, 8);
// 7

math.variance(1, 2, 3, 4);
// 1.25

math.lcm(2, 3, 4);
// 12
