Description

tuple_uniontuple_unionTupleUnionTupleUnionTupleUniontuple_union returns the union set from Set1Set1Set1Set1set1set_1 and Set2Set2Set2Set2set2set_2 in UnionUnionUnionUnionunionunion. For example, if Set1Set1Set1Set1set1set_1 contains the values [0,1,3,3,5] and Set2Set2Set2Set2set2set_2 contains the values [3,4], the output UnionUnionUnionUnionunionunion is [0,1,3,4,5]. The operator also allows mixed types of elements in the input tuples. However, the elements with different types will be considered as different elements, i.e. 1.0 and 1 are different. For example, the union of [2,5,3] and [4.0,5.0] is [2,3,5,4.0,5.0]. Please note that the order of tuple elements resulting from tuple_uniontuple_unionTupleUnionTupleUnionTupleUniontuple_union does not necessarily conform to the order in the input tuple.

Exception: Empty input tuples

If both of the input tuples are empty, the operator returns an empty tuple. If one of the input tuples is empty and the other is not, the output corresponds to the input tuple that is not empty.

HDevelop In-line Operation

HDevelop provides an in-line operation for tuple_uniontuple_unionTupleUnionTupleUnionTupleUniontuple_union, which can be used in an expression in the following syntax:

Union := union(Set1, Set2)
