Additional arithmetic types, such as __int128 or double double, and their
appropriate conversions are defined (<a href="#6.2.5">6.2.5</a>, <a href="#6.3.1">6.3.1</a>). Additional floating types may have
more range or precision than long double, may be used for evaluating expressions of
other floating types, and may be used to define float_t or double_t.
