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(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
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:
To test code coverage of the tests:
npm run coverage
