Math.js 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.

Install

Math.js can be installed via npm.

npm install mathjs

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

Use

Node

Math.js can be loaded via require:

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

Browser

Math.js can be loaded as a regular javascript file in the browser:

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