-Comparison of objects of the differing types depends on whether either
-of the types provide explicit support for the comparison.  Most numeric types
-can be compared with one another, but comparisons of :class:`float` and
-:class:`Decimal` are not supported to avoid the inevitable confusion arising
-from representation issues such as ``float('1.1')`` being inexactly represented
-and therefore not exactly equal to ``Decimal('1.1')`` which is.  When
-cross-type comparison is not supported, the comparison method returns
-``NotImplemented``.  This can create the illusion of non-transitivity between
-supported cross-type comparisons and unsupported comparisons.  For example,
-``Decimal(2) == 2`` and ``2 == float(2)`` but ``Decimal(2) != float(2)``.
