The Sky FP unit is IEEE-488, and thus will return NAN's and infinity when
appropriate.  The SUN printf routines recognize these as special cases and
print them specially.  Thus, I would expect all to work just find when using
the Sky board.

Isn't it interesting that Sunny Kirsten of Sun answered a totally different
question that wasn't even raised in Beblo's posting, and the correct answer
had to come from one of Sun's hottest competitors?
