I vote yes on motion 48 but with the following comments.
1. I would hope that any language in which interval arithmetic is
supported
would provide sufficient tools to read and write scalar numeric
quantities
to allow read/write or write/read isomorphism, and that therefore
Exact to Interval etc. are unnecessary.
2. Also .. any language .. would allow reading of numeric quantities with
rounding up or down, making the issue of enclosure moot. This might be
eased by defining NaI as an interval with a NaN endpoint.
3. I do not expect to ever have to use this part of an interval package.
44. I expect that the standard document could be made much simpler
by essentially leaving this out.
5. If some people feel otherwise and insist on internalizing
I/O into the standard and are willing to spend the time and effort to
refine it until there is a consensus among people who care about it, OK.
So I vote yes.
