You need to use CGAL::Exact_predicates_inexact_constructions_kernel for the triangulations, and then convert your data to the CGAL::Exact_predicates_exact_constructions_kernel to the the boolean operations.

The class template CGAL::Cartesian_converter<K1, K2> can help to convert from a kernel to another.
