Re: Clause 10, Expression Evaluation



suppose a language
supports a storage type (binary16 or decimal32) as a full-fledged
type on which all operations are supported: this would require an
effective WidenTo behind the scenes for conformance, right?


I think so.    The idea is that those storage types are too narrow to be
safe for any but trivial floating-point calculations - to keep roundoff
error to a manageable level, storage types should never be implemented
without a wider computational type.
