:ctype:`__int64`. They are always available in standard modes.

When attempting to pack a non-integer using any of the integer conversion
codes, if the non-integer has a :meth:`__index__` method then that method is
called to convert the argument to an integer before packing.
.. versionchanged:: 3.2
Use of the :meth:`__index__` method for non-integers is new in 3.2.
(5)
For the ``'f'`` and ``'d'`` conversion codes, the packed representation uses
the IEEE 754 binary32 (for ``'f'``) or binary64 (for ``'d'``) format,
regardless of the floating-point format used by the platform.

The ``'P'`` format character is only available for the native byte ordering
(selected as the default or with the ``'@'`` byte order character). The byte
order character ``'='`` chooses to use little- or big-endian ordering based
