OS X’s Calculator application is something I basically ignore. Between Spotlight and Terminal’s bc, I rarely if ever use it. So it was a pleasant and welcome surprise when TUAW reader Roberto Mateu gave us a heads up that Leopard’s calculator was updated with better RPN support.

Calculator has done RPN for some time–if you’re still running Tiger, you can see the old version by selecting View > RPN for any of the three calculator types. Under Tiger, the = button changed to Enter and that was about it. Leopard has updated the RPN calculator by adding multi-line entry so you can see your stack as it grows. It’s a much nicer way to use RPN and TUAW heartily approves.
