coinage.js v3.0.2

coinage.js

A javascript library for dealling with USD

Install

$ npm install coinage.js

Usage

Import the libary with

const USD = require('coinage')

There are 2 factory functions used to create instances of USD.

const money1 = USD.fromFloat(1.50)    // $1.50
const money2 = USD.fromFloat(150)     // $150.00
const money3 = USD.fromFloat(1.1)     // $1.10

const money4 = USD.fromString('1.50') // $1.50
const money5 = USD.fromString('150')  // $150.00
const money6 = USD.fromString('1.1')  // $1.10

Both fromFloat and fromString both restrict input to 2 decimal places.

// BAD

const money1 = USD.fromFloat(1.555)    // error
const money2 = USD.fromString('1.555') // error

API

Functions for basic math are provided. All instances of Money are immutable. Each of the following functions returns a new instance.
