    For the built-in types supporting :func:`round`, values are rounded to the
-   closest multiple of 10 to the power minus *n*; if two multiples are equally
-   close, rounding is done toward the even choice (so, for example, both
-   ``round(0.5)`` and ``round(-0.5)`` are ``0``, and ``round(1.5)`` is ``2``).
-   The return value is an integer if called with one argument, otherwise of the
-   same type as *x*.
