A set of consecutive values of an ordered base data type.
A dimensioned quantity expressing the result of a measurement act.
center.empty() or (low.empty() and high.empty())
If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.
The unit of measure specified in the Unified Code for Units of Measure (UCUM) [].
The magnitude of the quantity measured in terms of the unit.
An alternative representation of the same physical quantity expressed in a different unit, of a different unit code system and possibly with a different value.
A code specifying whether the set component is included (union) or excluded (set-difference) from the set, or other set operations with the current set component and the set as constructed from the representation stream up to the current point.
The arithmetic mean of the interval (low plus high divided by 2). The purpose of distinguishing the center as a semantic property is for conversions of intervals from and to point values.
The difference between high and low boundary. The purpose of distinguishing a width property is to handle all cases of incomplete information symmetrically. In any interval representation only two of the three properties high, low, and width need to be stated and the third can be derived.
