User-agent: Mutt/1.3.28i

If I enter this expression in a buffer

(* 85 1.1)

and evaluate it it using Ctrl-x-e, I get the following answer
displayed in the minibuffer:

93.50000000000001

If I evaluate this expression

(- 93.5 (* 85 1.1))

I get this answer in the minibuffer:

-1.4210854715202004e-14

Is this documented in the reference manual?  I was unable to find
anything about this kind of problem.

My Emacs was configured using `configure i386-debian-linux-gnu
--prefix=/usr --sharedstatedir=/var/lib --libexecdir=/usr/lib
--localstatedir=/var/lib --infodir=/usr/share/info
--mandir=/usr/share/man --with-pop=yes --with-x=yes
--with-x-toolkit=athena --without-gif' Important settings:
