Having used the HP67 and then the HP41C back in the day, I really missed RPN. This calculator neatly balances in my opinion the ease of use (easy desktop icon) and the efficiency of RPN. Glad the author took the time to write this!

This is the calculator that I usually end up using, so I'd like to give it 5 stars. But paste from clipboard doesn't work for me. Copy to clipboard works though. Also, I find it odd that it has a last answers function but no last x function, which I really, really miss. So, to get the last x function, I'm now using the version at http://fsch.awardspace.com/

Very nice - would say 5* if it had polar/rectangular conversions and did complex +-*/ . Thanks.

Muy complicada nada que ver con las HP
