Re: Edge case conversions, exceptions to IEEE FPA
Vladik et al,
I perceive that as something that would be completely new and would
entail a lot more work than what we have been discussing so far.
In particular, binary and decimal arithmetic, with directed roundings,
are already codified in IEEE 754-2008, and, except for possibly some
of the edge cases we have been discussing, the 754-2008 specifications
(including specifications of the directed rounding modes) can be used
directly in our interval standard.

Probably not for this standard, but how about adding arbitrary rational
numbers to the standard? There have been some programming environments
where we could manipulate exact rational numbers like 1/3, and they
often occur as coefficients.
Of course, we can always treat them as 1.0 /3.0 with exactly represented
1 and 3.
