Subject: (+ 5.1 0.1)
Date: Mon, 13 Jul 2009 03:57:39 -0700 (PDT) [thread overview]
Message-ID: <44632093-47cc-4907-bfa0-a3202f51657d@q40g2000prh.googlegroups.com> (raw)
First I used "emacs --no-init-file" to start my emacs-22.3, then I
typed (+ 5.1 0.1) in *scratch* buffer. However, when I evaluated this
expression, I got 5.199999999999999.
Can anyone tell me why did this happen?
I tried (+ 5.0 0.1) and (+ 5.2 0.1) and both gave the answers I had
expected.
