+
+Math.js is an extensive math library for JavaScript and Node.js. It features a flexible expression parser with support for symbolic computation, comes with a large set of built-in functions and constants, and offers an integrated solution to work with different data types like numbers, big numbers, complex numbers, fractions, units, and matrices. Powerful and easy to use.
+
+
+## Features
+
+- Supports numbers, big numbers, complex numbers, fractions, units, strings, arrays, and matrices.
+- Is compatible with JavaScript's built-in Math library.
+- Contains a flexible expression parser.
+- Does symbolic computation.
+- Comes with a large set of built-in functions and constants.
+- Has no dependencies. Runs on any JavaScript engine.
+- Can be used as a command line application as well.
+- Is easily extensible.
+- Open source.
+
+## Usage
+
+Math.js can be installed using npm or bower, or by [downloading](http://mathjs.org/download.html) the library.
+The library can be used in both node.js and in the browser.
+See the [Getting Started](http://mathjs.org/docs/getting_started.html) for a more detailed tutorial. To install math.js using npm:
+
+    npm install mathjs
+
+Math.js can be used similar to JavaScript's built-in Math library. Besides that,
+math.js can evaluate
+[expressions](http://mathjs.org/docs/expressions.html)
+and supports
+[chained operations](http://mathjs.org/docs/chained_operations.html).
+
+```js
+// 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]]
+math.derivative('x^2 + x', 'x');  // 2 * x + 1
+
+// expressions
+math.eval('12 / (2.3 + 0.7)');    // 4
+math.eval('5.08 cm to 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
+
+// chaining
+math.chain(3)
+    .add(4)
+    .multiply(2)
+    .done(); // 14
+```

+
+## Build
+
+First clone the project from github:
+
+    git clone git://github.com/josdejong/mathjs.git
+    cd mathjs
+
+Install the project dependencies:
+
+    npm install
+
+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.
+
+
+## Test
+
+To execute tests for the library, install the project dependencies once:
+
+    npm install
+
+Then, the tests can be executed:
+
+    npm test
+
+To test code coverage of the tests:
+
+    npm run coverage
+
+To see the coverage results, open the generated report in your browser:
+
+    ./coverage/lcov-report/index.html
