Egg Carton is a series of Ruby number helpers to help with reporting conversions and click-throughs.
Don't put all your eggs in one basket...
gem install egg_carton
The helper methods use a pre-calculate numberator and denominator with the goal of calculating an average or conversion. In many cases, counts are pulled from a database and then need to be displayed properly for reporting. These methods help with the display portion once the values have been calculated.
In Rails, helper methods are added to ActionView::Base, and as a result, available to views.
Average Method
average(1, 4)
# => 0.25
average(1, 4, 1)

conversion(1, 4, 2, :percentage => false)

conversion(1, 4, 1, :percentage => false)
# => 0.3
