acts_as_decimal

A simple gem for Rails 3 to make an attribute behave like it is floating point, being stored as an integer in the database. Tested with Ruby 1.8, 1.9, Rubinius 1.2.2 and JRuby 1.6.

Add it to your Gemfile:

gem 'acts_as_decimal'

And put this in your model, let’s say a Product with a :price attribute:

class Product < ActiveRecord::Base
  acts_as_decimal :price                    # Defaults to 2 decimal floating point values, or...
  acts_as_decimal :price, :decimals => 5    # ...as you wish!
end

Now you store and retrieve :price as a floating point:

product = Product.new
product.price = 12.30   
product.price              # => 12.30

But you still have access to the raw database integer value through :price_raw:

product.price_raw          # => 1230
product.price_raw = 4309   # product.price == 43.09

Note on Patches/Pull Requests

Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don’t break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
