This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.
Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.
In GNU Emacs 21.2.1 (sparc-sun-solaris2.8, X toolkit)
of 2002-09-24 on nob.dd.chalmers.se
configured using `configure --x-includes=/opt/pd/include/
--x-libraries=/opt/pd/lib --prefix=/rec/emacs-21.2/'

default-enable-multibyte-characters: t
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
Ok, I know why this happens:
(/ 5 4) => 1
But this behaviour is *highly* confusing:
(/ 5 4 2.3) => 0.4347826086956522
Cf. (/ 5 4.0 2.3) => 0.5434782608695653
At least there should be a warning in the manual.
