Subject: -0.0 treated as negative?
Date: Mon, 7 Jun 2010 07:00:42 -0700 [thread overview]
Message-ID: <20100607135908.M46502@ccrma.Stanford.EDU> (raw)
I just noticed a case where -0.0 is apparently negative:
scheme@(guile-user)> (/ 1.0 0.0)
+inf.0
scheme@(guile-user)> (/ -1.0 0.0)
-inf.0
scheme@(guile-user)> (/ 1.0 -0.0)
-inf.0
scheme@(guile-user)> (/ -1.0 -0.0)
+inf.0
scheme@(guile-user)> (negative? -0.0)
#f
And here's a separate oddity:
scheme@(guile-user)> (expt #t 0)
1
