A quantity constructed as the quotient of a numerator quantity divided by a denominator quantity. Common factors in the numerator and denominator are not automatically cancelled out. The data type supports titers (e.g., "1:128") and other quantities produced by laboratories that truly represent ratios. Ratios are not simply "structured numerics", particularly blood pressure measurements (e.g. "120/60") are not ratios. In many cases the should be used instead of the .
is an abstract generalization for all data types (1) whose value set has an order relation (less-or-equal) and (2) where difference is defined in all of the data type's totally ordered value subsets. The quantity type abstraction is needed in defining certain other types, such as the interval and the probability distribution.
If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.
The quantity that is being divided in the ratio. The default is the integer number 1 (one.)
The quantity that devides the numerator in the ratio. The default is the integer number 1 (one.) The denominator must not be zero.
