To use these functions, the Interval Feature is required.
The interval feature provides arbitrary functions to work with intervals in a data stream and algebraic operator (+, *, -, /, ^) to perform interval addition, subtraction, multiplication, division, and exponentiation.
Union(Interval, Interval)
Computes the union of the two intervals
Difference(Interval, Interval)
Computes the difference of the two intervals
Intersection(Interval, Interval)
Computes the intersection of the two intervals
