<p>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. </p>
