RPN Scientific X

RPN Scientific X is a scientific Reverse Polish Notation (RPN) calculator based on the venerable Hewlett Packard 10C scientific calculator. It was designed especially for Windows 10, is free, does not contain any advertisements, and does not collect information about you, your computer or your phone. It performs all of the 10C’s scientific math functions. RPN Scientific X has a 100 level stack and supports ten store and recall memory locations. Results can be displayed with up to nine decimal places of accuracy. When used on a desktop or tablet, it includes a “tape” to show results of calculations. The tape can be copied or cleared.
