What Is Rational Number?

Rational number in our representation is just numerator and denominator. ICE provides information about prices using numerators only. To get a real price you need to get the denominator from a product definition and then divide the numerator on the denominator. To simplify this we decided to use our own representation and always keep the denominator together with the numerator.
