Your example was that you'd get "something like [{1, 0.1}]", but do
you only require that e.g. {1, 2, 3} compares equal to {1.0, 2.0, 3.0},
i.e., that the only differences that may occur are due to integer <->
float conversions, or do you need to handle actual computed values, so
that {1,2,3} should compare equal to {1.0000001,2.0000001,3.0000001}?
In the first case, a simple == comparison on the whole term should be
enough. In the latter case you really have to unpack the structure and
handle each comparison separately.
