The documentation for marshal explicitly states that you should not use
it for such purposes.
There's also a version argument to dumps and dump (though the argument
list in the dump documentation doesn't say so), where version 0 is
pre-2.4, and version 1 is 2.4+. I don't think it's out of the question
to add a version 2 for 2.5+ that uses a better serialization for floats
(and it should probably add set/frozenset too since those are builtins
