<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">I've been using pgcalc2 as a desktop scientific calculator for a while because it emulates an HP calculator in RPN mode. It even has a half dozen skins to look like your favorite HP version. All of the scientific calculators I've found use algebraic mode and not RPN, but pgcalc2 does both. You can get it for Windoze too, but it's not free on that platform.<br><br>Would be a great PBI! <a href="http://www.freshports.org/math/pgcalc/">It's in ports.<br></a><br>http://www.pgcalc.net/<br><br>...Jeff<br></td></tr></table><br>
