[Bug libfortran/30694] minval/maxval with +/-Inf

[burnus at gcc dot gnu dot org]

------- Comment #26 from burnus at gcc dot gnu dot org  2007-10-18 18:22 -------
If I understand it correctly, there is a difference between
IEEE 754-1989 and the current draft of IEEE 754 (duped IEEE 754r), see also
http://groups.google.com/group/comp.lang.fortran/browse_thread/thread/33055faef528c075

IEEE 754r says that all operations with NaN yield NaN except of min and max
which give only NaN if all (i.e. both) arguments are NaN.

IEEE 754-1989 had no min/max functions and thus always NaN have to be produced
for maxval( huge(x), NAN ).
