I have done that for real(16), but I did not find a way to
infer anything for the decimal output.

What I have seen with real(16) is that at some point (say F70.50) the last
digits are 0's, but I don't remember having ever seen the same effects
on other reals: the output always look as the decimal representation
of the number viewed as an exact value, i.e., followed by an infinity of 0's.
