Math.js can be installed using npm or bower, or by downloading the library. The library can be used in both node.js and in the browser. See the Getting Started for a more detailed tutorial. To install math.js using npm:
npm install mathjs
// load math.js var math = require('mathjs'); // functions and constants math.round(math.e, 3); // 2.718 math.atan2(3, -3) / math.pi; // 0.75 math.log(1000, 10); // 3 math.sqrt(-4); // 2i math.pow([[-1, 2], [3, 1]], 2); // [[7, 0], [0, 7]] // expressions math.eval('12 / (2.3 + 0.7)'); // 4 math.eval('5.08 cm in inch'); // 2 inch math.eval('sin(45 deg) ^ 2'); // 0.5 math.eval('9 / 3 + 2i'); // 3 + 2i math.eval('det([-1, 2; 3, 1])'); // -7 // chained operations math.select(3) .add(4) .multiply(2) .done(); // 14
First clone the project from github:
git clone git://github.com/josdejong/mathjs.git
The project uses jake as build tool. To be able to run jake from the command line, jake must be installed globally:
sudo npm install -g jake
Then, the project can be build by executing jake in the root of the project:
cd mathjs jake
This will build the library math.js and math.min.js from the source files and execute tests.
To execute tests for the library, run:
