Math2 is an extended math library for JavaScript, compatible with the standard Math library of JavaScript. Math2 supports real values, complex values, units, strings, and matrices. It contains an extensive set of built-in functions, and comes with a flexible expression parser. Powerful and easy to use.

Install

Math2 can be installed via npm.

npm install math2

Alternatively, the library can be downloaded from github: math2.js, or minified: math2.min.js.

Use

Node

Math2 can be loaded via require:

var math2 = require('math2'),
    Complex = math2.type.Complex,
    Unit = math2.type.Unit;

console.log(math2.sqrt(25));           // 5

var c = new Complex(3, -4);
console.log(math2.sqrt(c).toString()); // 2 - i

var u = new Unit(45, 'deg');
console.log(math2.sin(math2.pi / 4));  // 0.7071067811865475
console.log(math2.sin(u));             // 0.7071067811865475

Browser

Math2 can be loaded as a regular JavaScript file in the browser:

<!DOCTYPE html>
<html>
<head>
    <script src="math2.js" type="text/javascript"></script>
</head>
<body>
    <script>
        var Complex = math2.type.Complex;
        var Unit = math2.type.Unit;

        console.log(math2.sqrt(25));           // 5

        var c = new Complex(3, -4);
        console.log(math2.sqrt(c).toString()); // 2 - i

        var u = new Unit(45, 'deg');
        console.log(math2.sin(math2.pi / 4));  // 0.7071067811865475
        console.log(math2.sin(u));             // 0.7071067811865475
    </script>
</body>
</html>
