@results = Product.all.select("*, `price` * 100 AS `price`")

or

class Product < ActiveRecord::Base
  def price
    super * 100
  end
end

or

class Product < ActiveRecord::Base
  def cents
    price * 100
  end
end

Add a virtual attribute to app/models/product.rb

class Product < ActiveRecord::Base
  ...

  def price_in_cents  # or some other appropriate name
    price * 100
  end
  ...
end

And use it as something like @results.first.price_in_cents
