Indicates whether the union function operates using a floating (full) precision model. If this is the case, then the unary union code can make use of the operation::union::OverlapUnion performance optimization, and perhaps other optimizations as well. Otherwise, the union result extent may not be the same as the extent of the inputs, which prevents using some optimizations.

Implements geos::operation::geounion::UnionStrategy.
