math.js

http://mathjs.org

Math.js is an extensive math library for JavaScript and Node.js. It features a flexible expression parser with support for symbolic computation, comes with a large set of built-in functions and constants, and offers an integrated solution to work with different data types like numbers, big numbers, complex numbers, fractions, units, and matrices. Powerful and easy to use.

Features

  • Supports numbers, big numbers, complex numbers, fractions, units, strings, arrays, and matrices.
  • Is compatible with JavaScript's built-in Math library.
  • Contains a flexible expression parser.
  • Does symbolic computation.
  • Comes with a large set of built-in functions and constants.
  • Can be used as a command line application as well.
  • Runs on any JavaScript engine.
  • Is easily extensible.
  • Open source.

Usage

Math.js can be used in both node.js and in the browser.

Install math.js using npm:

npm install mathjs

Or download mathjs via one of the CDN's listed on the downloads page:

    http://mathjs.org/download.html

Math.js can be used similar to JavaScript's built-in Math library. Besides that, math.js can evaluate expressions and supports chained operations.

// load math.js
const math = require('mathjs')

// functions and constants
math.round(math.e, 3)             // 2.718
math.atan2(3, -3) / math.pi       // 0.75
math.log(10000, 10)               // 4
math.sqrt(-4)                     // 2i
math.pow([[-1, 2], [3, 1]], 2)    // [[7, 0], [0, 7]]
math.derivative('x^2 + x', 'x')   // 2 * x + 1

// expressions
math.eval('12 / (2.3 + 0.7)')     // 4
math.eval('12.7 cm to inch')      // 5 inch
math.eval('sin(45 deg) ^ 2')      // 0.5
math.eval('9 / 3 + 2i')           // 3 + 2i
math.eval('det([-1, 2  3, 1])')   // -7

// chaining
math.chain(3)
    .add(4)
    .multiply(2)
    .done()  // 14

See the Getting Started for a more detailed tutorial.

Browser support

Math.js works on any ES5 compatible JavaScript engine: node.js 4 or newer, Chrome, Firefox, Safari, Edge, and IE11.

Though there is no official support for older browsers, math.js should still work on older browsers when using the es5-shim.

Documentation

Build

First clone the project from github:

git clone git://github.com/josdejong/mathjs.git
cd mathjs

Install the project dependencies:

npm install

Then, the project can be build by executing the build script via npm:

npm run build

This will build the library math.js and math.min.js from the source files and put them in the folder dist.

Test

To execute tests for the library, install the project dependencies once:

npm install

Then, the tests can be executed:

npm test

Additionally, the tests can be run on FireFox using headless mode:

npm run test:browser

To run the tests on remotely on BrowserStack, first set the environment variables BROWSER_STACK_USERNAME and BROWSER_STACK_ACCESS_KEY with your username and access key and then execute:

npm run test:browserstack

To test code coverage of the tests:

npm run coverage

To see the coverage results, open the generated report in your browser:

./coverage/lcov-report/index.html

Continuous integration testing

Continuous integration tests are run on Travis CI and BrowserStack every time a commit is pushed to github. The test results can be checked on https://travis-ci.org/josdejong/mathjs. Travis CI runs the tests for different versions of node.js, and BrowserStack runs the tests are run on all major browsers.

Travis CI     BrowserStack

Thanks Travis CI and BrowserStack for the generous free hosting of this open source project!
