Installation

In browser:

<script>
  (function() {
    var calcjs = window.calcjs;

In Node.js:

var calcjs = require('calcjs');
// using calcjs

Usage

// Addition
// 0.1 + 0.1 + 0.1
calcjs.add(0.1, 0.1, 0.1)
// return 0.3

// Subtraction
// 0.3 - 0.1 - 0.1
calcjs.sub(0.3, 0.1, 0.1)
// return 0.1

// Multiplication
// 0.1 * 0.1 * 0.1
calcjs.multi(0.1, 0.1, 0.1)
// return 0.001

// Division
// 10 / 5 / 2
calcjs.div(10, 5, 2)
// return 1


// Chain
// 0.1 + 0.2 * 0.1
calcjs.begin(0.1).add(0.2).multi(0.1).end()
// return 0.12
