sorry, I'm not sure what I was thinking about when I responded to your
statement, but I'll try again:

- maybe that implies that infinities and their reciprocals are in a class by
themselves, as neither are warranted to have some minimal precision, as both
exact and inexact representations have, but rather represent an underflow of
the minimal precision otherwise warranted by exact/inexact representations?
