  - union
```
Geometry union(Geometry g0,
               Geometry g1)
```
    Computes the union of two geometries. This method may throw a TopologyException if one is encountered.
    
    Parameters:
    
    g0 - a geometry
    
    g1 - a geometry
    
    Returns:
    
    the union of the inputs
  - isFloatingPrecision
```
boolean isFloatingPrecision()
```
    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 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.
    
    Returns:
    
    true if the union function operates using floating precision
