Math.js is an extensive math library for JavaScript and Node.js. It features a flexible expression parser and offers an integrated solution to work with numbers, big numbers, complex numbers, units, and matrices. Powerful and easy to use.
- Supports numbers, big numbers, complex numbers, units, strings, arrays, and matrices.
- Is compatible with JavaScript's built-in Math library.
- Contains a flexible expression parser.
- Supports chained operations.
- 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.
Math.js can be installed using Meteor add.
meteor add ecwyne:mathjs
Math.js can be used similar to JavaScript's built-in Math library. Besides that, math.js can evaluate expressions and supports chained operations.
// 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 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
// chained operations
math.select(3)
.add(4)
.multiply(2)
.done(); // 14Copyright (C) 2013-2014 Jos de Jong wjosdejong@gmail.com
