Typos on p.284 and p.324

[S Sridhar <sridhar%tekchips%tektronix.csnet@CSNET-RELAY.ARPA>]

p.284: A minor grammatical typo :
      Near the beginning of the last quarter of the page , the
sentence:
   "means the approximately the same as"  should read
   "means approximately the same as" 

p.324:  The second and third line: From the trace , it would appear
that the second argument to the floor function was intended to be 3
and not 2. So the 2 in these two lines should be replaced by a 3.

p.67: Another one pointed out by a colleague: At the beginning of the 
page it says: "The defun special form ...." and in the very next line
defun is said to be a macro. [ defun does not appear in the list
of special forms on p.57 ]. Light ?
