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)``. +Comparison of objects of the differing types depends on whether either of the +types provide explicit support for the comparison.
