@code{_Sat unsigned _Accum},
@code{_Sat unsigned long _Accum},
@code{_Sat unsigned long long _Accum}.
Fixed-point data values contain fractional and optional integral parts.
The format of fixed-point data varies and depends on the target machine.
Support for fixed-point types includes prefix and postfix increment
and decrement operators (@code{++}, @code{--}); unary arithmetic operators
(@code{+}, @code{-}, @code{!}); binary arithmetic operators (@code{+},
@code{-}, @code{*}, @code{/}); binary shift operators (@code{<<}, @code{>>});
relational operators (@code{<}, @code{<=}, @code{>=}, @code{>});
equality operators (@code{==}, @code{!=}); assignment operators
(@code{+=}, @code{-=}, @code{*=}, @code{/=}, @code{<<=}, @code{>>=});
and conversions to and from integer, floating-point, or fixed-point types.
