John Reid asks:
> Do we have a problem with IEEE_INT (see 17.11.11 in N2137)?

The answer to that is clearly NO.

Furthermore, it would be entirely inappropriate to put special wording =
into a single function out of many.  And even more inappropriate to dump =
the exact same wording all over the standard.

As it happens, if you want to know what the rounding modes mean, looking =
in 17.4 "The rounding modes" gives the exact correspondence between our =
rounding modes (and named constants) and the 60559 rounding-direction =
attributes, in paragraph 2.
