RE: Edge case conversions, exceptions to IEEE FPA
In engineering and science, when people write 1.5, they sometimes mean
not the exact number, but the fact that we know the coefficient with two
decimal digit accuracy, meaning that the actual value of this
coefficient can be between 1.45 and 1.55. This necessitates things like
1.50 meaning the interval [1.495,1.505] as opposed to [1.45,1.55].
In this case, we deal with a string, not with a real number, since real
numbers 1.5 and 1.50 are the same.
My understanding is that the second conversion from a strong in some
sense tries to capture this meaning.

Michel et al,
My stand (as a
member of the committee) is that float to
interval conversion should be to a singleton
interval. (However, see my comments about
external string to interval conversion.)
