# Documentation

[Math.js](http://mathjs.org) is an extensive math library for JavaScript and Node.js.
It features a flexible expression parser and offers an integrated solution
to work with numbers, big numbers, complex numbers, units, and matrices.
Powerful and easy to use.

This documentation of contains a getting started tutorial,
an extensive overview describing math.js on a high level, and a reference 
describing all available functions, constants, and units in detail.
