The return value is an integer if called with one argument, otherwise of the

same type as *x*.

.. note::
|

|
||||
The behavior of :func:`round` for floats can be surprising: for example,
|
||||
``round(2.675, 2)`` gives ``2.67`` instead of the expected ``2.68``.
|
||||
This is not a bug: it's a result of the fact that most decimal fractions
|
||||
can't be represented exactly as a float. See :ref:`tut-fp-issues` for
|
||||
more information.
