Very nice, I'm much interested in this project.

When I run 'mathdemo.ex', I got the following error message:

     C:\TEMP\matheval.e:143
     resolve_math_ref has not been declared
         id = resolve_math_ref( ref )
                             ^

Also, I don't understand some parts of the documentation, for instance:

<quote>
[const]
Floor
{ FLOOR, ARG1, { } }
Returns: Greatest integer less than ARG1.
<unquote>

How can a constant return something?


<quote>
[func]
Simplify
Returns: Algebraically simplified matheval sequence.
<unquote>

What arguments does 'Simplify' take, and what exactly is a 'matheval
sequence'?


I like math, but it's dry stuff. So I think it would be nice, if there
were some examples in the documentation.
Thank you for this library! I believe it's great, but the documentation
is somewhat confusing for me, so I think I can't really see it's full
potential. That's just me, of course.

Best regards,
   Juergen
