There are two set-theoretic operations defined on RealBox objects.
the union of the RealBox objects a and b
the intersection of the RealBox objects a and b
the intersection of the RealBox b with the non-negative real axis
Note that there are also predicates Contains and Overlaps that are set-theoretic in nature which are documented in RealBox[Predicates].
Use the 'precision' = n option to control the precision used in these methods. For more details on precision, see BoxPrecision.
Note that an intersection can only be formed for RealBox objects that have nonempty intersection.
Error, (in RealBox:-extIntersection) non-overlapping real boxes
This is not necessary, however, for unions.
The RealBox[SetTheory], RealBox:-Union, RealBox:-Intersection and RealBox:-NonNegativePart commands were introduced in Maple 2022.
For more information on Maple 2022 changes, see Updates in Maple 2022.
