Subject: Re: COMPLEMENT, again From: Erik Naggum <erik@naggum.no> Date: 1999/06/21 Newsgroups: comp.lang.lisp Message-ID: <3138981460897056@naggum.no> * Erik Naggum <erik@naggum.no> | (define-complement = /=) interestingly, this (and many other) seemingly complementary functions are only complementary with two arguments. with one argument, as in (= 1), most of these predicates yield true, and a complement should yield false. with three or more arguments, as in (= 1 1 2), both may be false and (not (= ...)) is thus very different from (/= ...). oh, well. #:Erik -- @1999-07-22T00:37:33Z -- pi billion seconds since the turn of the century
