--- Comment #5 from joseph at codesourcery dot com <joseph at codesourcery =

I think the rules in Annex F allowing spurious "inexact" and "underflow",=20
"unless stated otherwise", apply here (glibc limits spurious underflow to=20
cases where the returned result would be possible for an underflowing=20
computation).  (I consider the rules about functions bound to IEC 60559=20
operations, and about functions with qNaN argument returning qNaN with no=20
exceptions, to be "stating otherwise", but not the rules stating the value=
=20
of a result for a non-NaN argument.)

--=20
