POSIX doesn't say what should happen with infinities or NaNs, so Awk
can do as it pleases.

The C99 Standard says that printf can print either "inf" or
"infinity"; it's implementation-defined.  Similarly, NaNs are printed
as either "nan" or "nan(n-char-sequence)".  In either case, "-" is
prepended if the sign bit is negative.

Presumably Awk should do the same as C99.  However, I don't think it's
a big deal if Awk does something different on old-fashioned hosts like
Solaris 8 that don't have proper C99 support.
