Inheritance diagram for RatioPtr: Collaboration diagram for RatioPtr:Represents rational number. Use this object to wrap rational number when you need to add fraction to lists, dictionaries and other containers which accept IBaseObject and derived interfaces.
Rational numbers are defined as numerator / denominator.
