"There are no infinities in the standard numbers of Common Lisp"
(this is repeated at the bottom of page 202 of aluminum edition.)
is inconsistent with the statement on p 19 of the same
edition, "... should approximate IEEE proposed standard ..." which
has infinities. Keeping 1/0 is probably less trouble than making
it an error.
For those of you who might think that arithmetic has been settled in a
correct and standard way in CL, I think that what has happened is that
people who have practical experience with error analysis and scientific
support have "tuned out" on CL, since it attempts to set a pseudo-standard
which is at odds with the IEEE (nearly adopted) standard.
