Juergen, what i think you're talking about is significant digits and significant
decimals. there's some excellent discussions of them at
   http://mathforum.org/dr.math/ 
and in particular
   http://mathforum.org/library/drmath/view/56375.html
   http://mathforum.org/library/drmath/view/59014.html

there are no Euphoria libraries that i know of that deal with this, since the
results of any multiplication, division, addition, substraction, sqare root,
etc., can vary considerably dependent on what the user wants. figuring taxes is
different (between Europe and the US, for example), rounding is different (which
digit to base the rounding on, round up, round down, truncate), scientific
calculations are different, etc.

what i've done with my apps is basically have the user make the choice
beforehand of the precision of any calculation.

hope that helps,
