Yes, I know, it is just a clarification of what the standard itself
The standard does not disallow them, as long as the arithmetic can be
modelled with an integer base. You may note that the radix given
is not necessarily the actual radix of the base arithmetic, nor is
it necessary that the base arithmetic is floating-point. The only
requirement is that it can be modelled as if it follows such a model,
and indeed, nearly every arithmetic can be modelled as such.
That is all irrelevant as the standard allows all operations to be
as inexact as you wish, the only requirement is about the round-trip
conversion.
