Dozecal 1.0.7

Dozecal stands out as an educational RPN (Reverse Polish Notation) calculator designed to facilitate the use of Base Twelve in mathematical and scientific contexts. This tool supports essential mathematical functions in both DUODECIMAL and DECIMAL modes, seamlessly converting inputs as users switch between these systems.

The calculator's trigonometric operations rely on degrees for measurement, catering to standard conventions in mathematics. For those interested in exploring the concept of Base Twelve further, the Dozenal Society of America provides valuable resources.

Utilizing RPN may initially appear complex; however, it offers significant advantages over traditional algebraic notation once mastered. The calculator operates with a stack system, where operations involving two numbers utilize the bottom layers of the stack (X and Y). To input numbers, users press ENTER to advance the stack and separate one entry from the next. Arithmetic operations can be performed by entering the first number, pressing ENTER to isolate it from the second, entering the second number, and then selecting an operator, such as +, -, *, or /. The result is displayed immediately following the operator key press.

For example, to calculate 3 + 4, the user follows this key sequence: 3 ENTER 4 +, yielding a result of 7. Notably, the outcome of an operation can be directly used as an operand without requiring an additional ENTER press. Thus, to add 2 to the previous result, one simply inputs 2 +, resulting in 9.

To extend this further with an illustrative calculation such as 5 * (3 + 4), the user would enter: 3 ENTER 4 + 5 *, or alternatively: 5 ENTER 3 ENTER 4 + *.

It is important to note that while Dozecal aims for high precision in calculations, there may be occasional discrepancies. Users are encouraged to report any inaccuracies to johan@unumdesignum.com for resolution.
