But there are no differences with 6.3.1.4 (when converting to a floating type):
in both cases, either the value can be represented exactly, in which case it is
unchanged, or it cannot, in which case it is rounded. When doing a conversion
to some given type, the C standard does not care of the origin type of the
value.
In any case, this is orthogonal to the rules given by 6.3.1.8 (which cover
extra precision and range).
