If such multipolygon is subtracted the result is a polygon with touching holes enclosing interior. Such polygon is invalid: "Geometry has disconnected interior". The result should be two polygons, one...

hausdorff is not symmetric - that should be added to the documentation

2

The Hausdorff algorithm is not symmetrical and can give unexpected results. SEE COMMENTS BELOW - we should fix the documentation. Minimal case: ``` #include namespace bg = boost::geometry; template double...

Difference: not the right set of points returned. Rounding issue?

Hi, Please have a look at [the issue on godbolt](https://godbolt.org/z/v94vceE1K). As you can see, points are disappearing when they should not. My issue is that I suspect rounding to remove...
