By the way, my code triggered CGAL::Uncertain_conversion_exception. I don't konw how it influence the result. @sloriot @afabri @lrineau L @marv Sorry to bother you, but really need help.

I further observed the results, and it seems to be caused by the numerical precision. The numerical precision of the tetrahedron division is too precise, which leads to a difference...
