rpCalc project started out as a little program written to try out various Python GUI toolkits. But I ended up using it all the time (it's much quicker to pull it up than to pull an actual HP calculator out of the desk), and I made several improvements.
So I decided to make it available to others who also like RPN calculators.
Here are some key features of "rpCalc":
· 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.
· 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.
· Qt (Version 2.3 or 3.x)
· Python (Version 2.1 or higher)
· PyQt (Version 2.4 or higher)
What's New in This Release: [ read full changelog ]
· A new base conversion dialog was added. It shows values in hexadecimal, octal and binary bases. Push buttons or keyboard prefixes can be used to allow entry of a value in one of these bases.
· A colon (":") can optionally be used as a prefix when typing commands. This is useful in hexadecimal entry mode for commands starting with letters "A" through "F".
· New options have been added for alternate base conversions. The number of bits and whether to use two's complement for negative numbers can be set.
· A display option was added to separate thousands with spaces in the main "LCD".
· An engineering notation display option was added that only shows exponents that are divisible by three.
· Keyboard number and function entry continue to work when the Extra Data window has focus.
· The ReadMe file has been updated.
