RPNCalc is a scientific calculator which uses Reverse Polish Notation. RPNCalc has the ability to store multiple values, and includes functions to modify the order of values in the stack.

Additional Features:

* up to 100 values can be saved in memory

* the last three values in the stack are displayed

* stored values are preserved when the app exits

* memory and stack values from the previous use

are restored when RPNCalc restarts

* audible "clicks" provide feedback for button presses

BindleBinaries is continuously improving RPNCalc by incorporating user requests and suggestions into new releases. These new releases are made available as free upgrades for existing users.

Known Issues in version 1.1:

* % performs (x * 0.01) rather than (y * (x * 0.01))

* EE performs (y * 10^x) rather than mimicking the behavior of HP calculators

* Constants cannot be used unless the stack contains at least two values

The known issues will be resolved in the next version which is planned to be released before August 31, 2008. BindleBinaries has implemented a beta testing program to help insure issues, such as those above, are fixed prior to release.

Once a good RPN calc, now useless

Unusable with OS 3.0. Several reports of problems on dev website since mid June were denied, now accepted. Still no fix. No updates since July 2008. Recommed looking at other options.
