Re: mid-rad, inf-sup, etc.
Well, we've talked about the "good" and the "bad." Now, how about
the "ugly." I may be run out of town by some 754'ers for bringing
this up, but, speaking of many different allowable formats, we
could conceivably allow separate formats for mid-rad and inf-sup.
(I suppose we HAVE brought this up before.) However, in particular,
I remind people that 754-2008 has two separate formats for
and decimal, mainly to accommodate two manufacturers who had
developed two different formats prior to standardization. My
understanding is that this is to be avoided if at all possible,
but are the differences between and separate advantages of
mid-rad and inf-sup arithmetic sufficient to warrant standardizing
separate interchange formats, along with conversion rules?

P.S. I guess we're still a ways from actually approving 6.1 and
6.2. I'll see if we can work up a set of guess-timates on
when we'll actually complete the entire process.
P.P.S. Sorry about digressing a bit from the original thread.

For interval arithmetic, with two range end components (or a middle and
one or two radii) and optionally decorations we have many possibilities.
For interchange part of it should be specified, but for compatibility
with existing hardware and software some should not.
