strange behaviour with simple decimals

As do many people.
However, when a beginner (and I have heard suggestions of using Maxima
in, say, Calc courses) types something in, they probably (not
unreasonably) expect Maxima to work with the data they enter.  It does
not.  Unless people feel that Maxima should only be used by experts,
this isn't something that should be shrugged off or delegated to a
footnote.  It should be emphasized early.  I just glanced through the
first few pages of the manual, and I didn't come across anything along
the lines of "Maxima may convert some numbers you type in to other
numbers", and it should be there.

That's a pretty good idea.
