PJ> I don't think it is the difference you want to mark in this case. :-) PJ> But, of course, you are right. and you are talking about two separate but related issues. one is how you store and calculate money values and the safest way is to use integer math with the smallest monetary units you can use (you can calc in .00001 cents if you need to). the other part is how to properly printout a money value with properly handled precision and formatting. given an integer storage of the right scaling, conversion for printing is easy and then all you have to deal with is formatting. if you want to get really nasty and dirty, develop a decimal math library with controllable precision and scaling. :) uri -- Uri Guttman ------ [EMAIL PROTECTED] -------- http://www.stemsystems.com --Perl Consulting, Stem Development, Systems Architecture, Design and Coding- Search or Offer Perl Jobs ---------------------------- http://jobs.perl.org
