Dear Ed and Cameron,

Me too. Very nice.

Am I wrong in thinking that you can use that library without being 
forced to calculate in Floats, i.e. can one use Rationals, Sqrts,
continued fractions, whatever as matrix entries ?

Then, its accuracy should only be limited by the space available on
the machine.

Best regards,

Axel
