// Load the math.js core
var core = require('../../core');

// Create a new, empty math.js instance
// It will only contain methods `import` and `config`
var math = core.create();

// load the data types you need. Let's say you just want to use fractions,
// but no matrices, complex numbers, bignumbers, and other stuff.
//
// To load all data types:
//
//     math.import(require('../../lib/type'));
//
math.import(require('../../lib/type/fraction'));

// Load the functions you need.
//
// To load all functions:
//
//     math.import(require('../../lib/function'));
//
// To load all functions of a specific category:
//
//     math.import(require('../../lib/function/arithmetic'));
//
math.import(require('../../lib/function/arithmetic/add'));
math.import(require('../../lib/function/arithmetic/subtract'));
math.import(require('../../lib/function/arithmetic/multiply'));

math.import(require('../../lib/function/string/format'));

// Use the loaded functions
var a = math.fraction(1, 3);
var b = math.fraction(3, 7);
var c = math.add(a, b);
console.log('result:', math.format(c)); // outputs "result: 16/21"

// Now, when bundling your application for use in the browser, only the used
// parts of math.js will be bundled. For example to create a bundle using
// browserify:
//
//     browserify custom_loading.js -o custom_loading.bundle.js
