Nevertheless, there are ways to print floating point numbers readably. http://portal.acm.org/citation.cfm?id=93559 e -- Doug Currie Londonderry, NH, USA ----------------------------------------------------------------------------- To unsubscribe, send email to [EMAIL PROTECTED] -----------------------------------------------------------------------------
