Math Formula

Simple JavaScript library to solve math equations

Installation

Download the file dist/mf.js and import it to your project.

If you use TypeScript or want to have types included, you can import the dist/mf.d.ts too. You only have to put the file in the same directory as the source file.

Usage

To create and evaluate a formula, you'll have to initialize an enviroment first. Then you can create a formula manager with this enviroment. Then you can parse your formula in form of a string into the parse() function and call the evaluate() function on the result of the parser.

Note here: The enviroment has to be initialized via the static createDefault() method because the constructor is private

import { Enviroment, FormulaManager } from "./mf";

const enviroment = Enviroment.createDefault();
const manager = new FormulaManager(enviroment);

const formula = "2 + 2";
console.log(manager.parse(formula).evaluate());

// => this should log "4"

For an interactive example, look at the test.js file.
