This is a simplier version of the Money class which comes with the [Money Gem](https://github.com/RubyMoney/money).

It doesn't try to handle currency conversions but simply wraps an amount of money into a [BigDecimal](http://www.ruby-doc.org/stdlib-2.0/libdoc/bigdecimal/rdoc/BigDecimal.html) instance to avoid precision issues with floating point arithmetic operations.

Features:

- doesn't monkey-patch [Ruby core types](https://github.com/RubyMoney/money/blob/master/lib/money/core_extensions.rb)

- less than 100 lines of code

- currency formatting support, e.g. `CrazyMoney.new("1234.56").with_currency("NZD") #=> "$1,234.56"`

- easy to integrate with Rails (see [Rails](#rails))

## Usage

```ruby

amount = CrazyMoney.new("13.37")

amount > 1 #=> true

amount == 13 #=> false

amount == 13.37 #=> true

amount == CrazyMoney.new(13.37) #=> true

amount.cents.to_i #=> 1337

amount.with_currency("NZD") #=> "$13.37"

```

### Rails

At the moment, there is no built-in support for Rails but you can use this initializer as a drop-in

replacement for the `monetize` helper that is provided by the Money Gem.

```ruby

# config/initializers/crazy_money.rb

class ActiveRecord::Base

  class << self

    def monetize attribute_cents

      attribute = attribute_cents.to_s.sub(/_cents$/, "")

      define_method attribute do

        CrazyMoney.new(send(attribute_cents)) / 100

      end

      define_method "#{attribute}=" do |value|

        send("#{attribute_cents}=", CrazyMoney.new(value).cents)

      end

    end

  end

end

```
