Constants are defined within the scope of the current class and are made available to all child classes, unless they're overridden:


Pi = 3.141592

class OtherPlanet
  Pi = 4.5

  def OtherPlanet.circumference_of_circle(radius)
    radius * 2 * Pi
  end
end

puts OtherPlanet.circumference_of_circle(10)
puts OtherPlanet::Pi
puts Pi
