Welcome to ConversMoney gem

With this gem you can convert different currencies just giving the conversion rates with the fixed amount (main based 1 currecy value 'EUR' in the example below) ant the exchange rate.

For more options please check the examples.

Installation

Add this line to your application's Gemfile:

gem 'convers_money'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install convers_money

Usage

Configure the currency rates with respect to a base currency (here EUR):

ConversMoney.conversion_rates('EUR', {
  'USD'     => 1.11,
  'Bitcoin' => 0.0047
})

Instantiate money objects:

fifty_eur = ConversMoney.new(50, 'EUR')

Get amount and currency:

fifty_eur.amount   # => 50
fifty_eur.currency # => "EUR"
fifty_eur.inspect  # => "50.00 EUR"

Convert to a different currency (should return a Money

instance, not a String):

fifty_eur.convert_to('USD') # => 55.50 USD

Perform operations in different currencies:

twenty_dollars = ConversMoney.new(20, 'USD')

Arithmetics:

fifty_eur + twenty_dollars # => 68.02 EUR
fifty_eur - twenty_dollars # => 31.98 EUR
fifty_eur / 2              # => 25 EUR
twenty_dollars * 3         # => 60 USD

Comparisons (also in different currencies):

twenty_dollars == ConversMoney.new(20, 'USD') # => true
twenty_dollars == ConversMoney.new(30, 'USD') # => false

fifty_eur_in_usd = fifty_eur.convert_to('USD')
fifty_eur_in_usd == fifty_eur          # => true

twenty_dollars > ConversMoney.new(5, 'USD')   # => true
twenty_dollars < fifty_eur             # => true
