Form the convex hull with the value. The convex hull is defined over ordered
domains and is the smallest contiguous superset (interval) that of all the

Form the periodic hull with the value. The periodic hull is defined over
ordered domains and is the periodic set that contains all contiguous
supersets of pairs of intervals generated by the operand periodic intervals.
