. . .
Perhaps we need a separate chapter on non-interval operations, or move
clause 13.7 to the end of Chapter 1. We also had Motion M0024.03 which
required availability of explicit directed-rounding for the basic point
arithmetic operations (which comes for free with 754-2008, but could be
an additional requirement for non-754 implementations). This belongs in
the same place.

I doubt it was Michel's intention to raise this issue but I will:
Can we (or should we) restrict implementations to 754-2008? Given
its wide acceptance throughout the world, it would not restrict our
customers much. (Or would it?) And, an underlying arithmetic which
is both good & well defined would make the rest of our task much
easier. (There are specific implementations of intervals already
written in 754 & it would allow us to write new features into 1788
as proof of concept.)
What say you folks?
Just curious...
