# Money::Collection

Calculating sum/min/max on a bunch of Money objects, with __accuracy__ and __efficiency__.

This is achieved by minimizing number of currency conversions and object creations.

For large collections, sum/min/max can perform up to 4 times as fast. For small collections (n<10), it can perform at least 2 times as fast.

## Installation

Add this line to your application's Gemfile:

```ruby

gem 'money-collection'

```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install money-collection

## Usage

Here is the demo of the Money::Collection library:

```ruby

require 'money'

require 'money/collection'

c = Money::Collection.new( [money1, money2] )

c << money3

c.concat [money4, money5]

c.sum

c.sum('TWD') # returns sum in TWD currency.

c.max

c.min

```

For more, please check the API documentation.
