      ``ndigits`` is negative), again rounding half toward even.  This
      method can also be accessed through the :func:`round` function.

   .. method:: __format__(format_spec, /)

      This method provides support for float-style formatting of
      :class:`Fraction` instances via the :meth:`str.format` method, the
      :func:`format` built-in function, or :ref:`Formatted string literals
      <f-strings>`. The presentation types `"e"`, `"E"`, `"f"`, `"F"`, `"g"`,
      `"G"`` and `"%"` are supported. For these presentation types, formatting
      for a :class:`Fraction` object `x` behaves as though the object `x` were
      first converted to :class:`float` and then formatted using the float
      formatting rules, but avoids the loss of precision that might arise as
      a result of that conversion.

      Here are some examples::

      >>> from fractions import Fraction
      >>> format(Fraction(1, 7), '.40g')
      '0.1428571428571428571428571428571428571429'
      >>> format(Fraction('1234567.855'), '_.2f')
      '1_234_567.86'
      >>> f"{Fraction(355, 113):*>20.6e}"
      '********3.141593e+00'
      >>> old_price, new_price = 499, 672
      >>> "{:.2%} price increase".format(Fraction(new_price, old_price) - 1)
      '34.67% price increase'
