This is a great calculator!
This is a great calculator which functions not only as a regular or scientific calculator, but as an RPN calculator as well. Although I was not familiar with Reverse Polish Notation, since getting this calculator, I am learning and becoming accustomed to RPN, and find I am starting to prefer this to the regular calculator. Pcalc also includes a large number of conversion factors and is very customizeable to your preferences in appearance and functionality. I am using Pcalc on an iPod Touch and and IPad Mini and have found it is well worth the money.
