Re: more editorial comment on format
Personally, I think that if you need to use
more than ~a, ~s, ~%, ~t, and ~~, you should be writing Lisp code to
do the formatting instead of using this crufty embedded language that
bears no resemblance or relationship to the rest of Common Lisp.
I heartily agree! Being a relative novice at using FORMAT (except in
the most straightforward way), I've spent far too much time trying to
get format control strings to do what I want. This seems like a case
of the solution being harder than the problem...
It's also unfortunate that there aren't *functions* provided to do some
of the nastier numeric formatting, like ~e and friends.
Well, you can always:
(defun exp-floating-point (w d e k overflow-char padchar expchar)
(format nil "~v,v,v,v,v,v,vE" w d e k overflow-char padchar
