Dozecal vs Calculator Mate

Dozecal is an educational RPN* calculator to promote the use of Base Twelve in math and science. The usual math functions are available in both DUODECIMAL and DECIMAL modes. Conversion is automatically made when switching from one mode to the other one. Trigonometric operations uses DEGREE as unit of measure. For more information about Base 12, please visit the Dozenal Society of America. * RPN : the Dozecalc calculator uses the Reverse Polish Notation (RPN). This notation seems complex but has many advantages over algebraic notation and is more intuitive once you have understood the idea. The calculator has a stack and any operation that requires two numbers is using the bottom stack layers (X and Y). Key ENTER to push the stack up and separate one number from the next. To perform arithmetic, key in the first number, press ENTER to separate the first number from the second, then key in the second number and then select and operator such as the numerical functions +, -, * or /. The result appears immediately after you press the numerical function key. The operator is keyed in only after both operands are in the stack. Example: calculate 3 + 4 Key sequence: 3 ENTER 4 + Result: 7 The result of any operation may itself become an operand. You do not need to press enter again to use the result. The "7" is already entered. Example: add 2 to the previous result Key sequence: 2 + Result: 9 Example: calculate 5 * (3 + 4) Key sequence: 3 ENTER 4 + 5 * Alternate key sequence: 5 ENTER 3 ENTER 4 + * Disclaimer: results and precision may occasionally be incorrect.
