math.js

http://mathjs.org Original Documentation

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.

Features

  • 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.

Usage

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(); // 14
