I don't think I would want my Lisp to be able to integer-decode-float
a double-float positive infinity, assuming that that is what (expt
9.9d0 9999) has returned.  

    >> (integer-decode-float (sin (expt 9.9d0 9999)))

Hm, sin of double-float positive infinity is negative?  How do you
know?  Or is that really decoding a double-float NaN?

I wouldn't like either of these.

IMHO
