The ``'q'`` and ``'Q'`` conversion codes are available in native mode only if
the platform C compiler supports C :c:type:`long long`, or, on Windows,
:c:type:`__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.

(3)
The ``'n'`` and ``'N'`` conversion codes are only available for the native
size (selected as the default or with the ``'@'`` byte order character).
For the standard size, you can use whichever of the other integer formats
fits your application.
(5)
(4)
For the ``'f'``, ``'d'`` and ``'e'`` conversion codes, the packed
representation uses the IEEE 754 binary32, binary64 or binary16 format (for
``'f'``, ``'d'`` or ``'e'`` respectively), regardless of the floating-point
format used by the platform.

(5)
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
on the host system. The struct module does not interpret this as native
ordering, so the ``'P'`` format is not available.

(6)
The IEEE 754 binary16 "half precision" type was introduced in the 2008
revision of the `IEEE 754 standard <ieee 754 standard_>`_. It has a sign
bit, a 5-bit exponent and 11-bit precision (with 10 bits explicitly stored),
