 Precision precision)

Description copied from interface: MergeOperator

The operator uses the abstractState1 to weaken abstractState2 depending on precision. Thus, it is asymmetric regarding its first two parameters. E.g., return abstractState2 for no merging. To guarantee the correct behavior of the algorithm implementations must have no side effects.
