BigDecimal Price

Did you know that decimal columns are great for storing prices in Rails apps?

Well, they are.

This little gem ensures that if you have, say a price column on a database, when you call that price method on your model, it will come out formatted like a price.

eg.

<%= @item.price %>

will out put 10.90, even if the decimal value is 10.9

Installation

Just add this to your gemfile:

gem 'big_decimal_price'

Lovely.
