POLYMATH

GETTING STARTED

Installing with NPM

$ npm install polymath

Browser

<script src="node_modules/polymath/bundles/polymath.js"></script>
<script>
	console.log(polymath.parse("2x^3 + 4x^2 - 3x + 12"));
</script>

Node

const polymath = require('polymath');
let polynomial = polymath.parse("2x^3 + 4x^2 - 3x + 12");

USAGE

CONSTRUCTION

From a String: polymath.parse('2x^3 + 7x^2 - 3x + 2')

Parsing is done using a parsing expression grammar. See PEG.js

BASIC ARITHMETIC

Polynomial.add(poly: Polynomial): Polynomial
