This is certainly far more than needed even though resolution decrease at longer distance. Decimal point may be moved to get a small range or large number but number of significant bits stay the same. > Cheers, > Philipp Nicklas Karlsson ------------------------------------------------------------------------------ Transform Data into Opportunity.
