- Supports numbers, big numbers, complex numbers, fractions, units, strings, arrays, and matrices.
- 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.
- Is easily extensible.
- Open source.
Math.js can be used in both node.js and in the browser.
Install math.js using npm:
npm install mathjs
Note that when using mathjs in a TypeScript project, you will have to install type definition files too:
npm install @types/mathjs.
Or download mathjs via one of the CDN's listed on the downloads page:
// 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.
Though there is no official support for older browsers, math.js should still work on older browsers when using the es5-shim.
First clone the project from github:
git clone git://github.com/josdejong/mathjs.git cd mathjs
Install the project dependencies:
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.
To execute tests for the library, install the project dependencies once:
Then, the tests can be executed:
Additionally, the tests can be run on FireFox using headless mode:
npm run test:browser
To run the tests remotely on BrowserStack, first set the environment variables
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:
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.
Thanks Travis CI and BrowserStack for the generous free hosting of this open source project!
