var math = require('mathjs'),
    Complex = math.type.Complex,
    Unit = math.type.Unit;

console.log(math.sqrt(25));           // 5

var c = new Complex(3, -4);
console.log(math.sqrt(c).toString()); // 2 - i

var u = new Unit(45, 'deg');
console.log(math.sin(math.pi / 4));  // 0.7071067811865475
console.log(math.sin(u));             // 0.7071067811865475

Build

To clone the project from github:

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

The project uses jake as build tool, and must be installed globally. After jake is installed, the project dependencies can be downloaded using npm. Then the project can be build by executing jake in the projects root.

cd mathjs
sudo npm install -g jake
npm install
jake

When jake is executed, it will generate the library math.js and math.min.js from the source files, and will test the library.
