rpCalc Features

• Uses reverse polish notation, similar to most Hewlett-Packard calculators.
• The number, operator or command text on any key can be typed, or the mouse can be used to hit the key.
• If desired, the four RPN registers can be shown in the main display.
• A separate window can display the four RPN registers, a history of recent calculations, or the contents of the ten memory registers.
• A separate window converts to and from other number bases (hexadecimal, octal and binary).
• Any values from the extra windows can be copied to the calculator display or to the clipboard.
• Options can be set to control the display of numbers and the initial window configuration.
