DIV Calculator is a EURO Converter and an easy to use scientific calculator.
It uses the so-called Reverse Polish Notation (RPN): Numbers must first be entered on the stack before a mathematical operation can be performed on them
(more information and examples). If you never used this method before you might get a little confused in the beginning. Don't worry, after a while you will see the benefits.
The EURO Converter allows the user to convert values between all currencies involved in the EURO and one extra user-defined currency.
The scientific calculator supports most common operations: Square root (Sqrt), Square (x^2), Power (x^y), Exponentiation (e^x), Logarithms (ln, log), Percent (%) and Percent Change (%ch), Pi, Inversion (1/x) and Modulo (Mod).
Binary calculus is also included (conversion between decimal, hexadecimal, octal and binary) (especially useful for developers).
Other conversions: Temperatures (°C, °F), Weights (kg, ounce, pound), Distances (m, inch, foot, mile) and many more. Mathematical operations can be performed on these values. For example, when multiplying a distance with an area, the result is a volume.
The setup program (DIVCalculatorSetupMips.exe or DIVCalculatorSetupArm.exe) can be run from any Windows platform (9x, Me, NT, 2000).
The setup program will first install the Pocket PC CAB files onto the desktop computer. It then launches Microsoft ActiveSync to install DIV Calculator on the Pocket PC.
The setup program sets the custom currency to US Dollar with an exchange rate of 0.9 (1 EURO = 0.9 USD).
- When multiplying high numbers, the result may be wrong (currently there is no overflow check).
- The value added to the stack when tapping the [c] button (= speed of light) is wrong if for the Speeds type the selected sub-type is [d]/[t] (see
Speeds).
- Only the MIPS and ARM CPUs are supported (like the Casio Cassiopeia and the Compaq iPaq).
- The setup program does not include the mfcce300.dll file. Most Pocket PC manufacturers deliver this file in the ROM of the PDA. If after installation you are not able to start DIV Calculator, verify that mfcce300.dll is located in the \Windows directory of your Pocket PC. If not, please download this file from

Changes to Version 1.1
Added a menu and an About dialog.
Added the functionality to perform operations on different types of values. For example, when multiplying a distance with an area, the result is a volume.
Changes to Version 1.0
Added a user-defined custom currency.
Save settings (stack content, selected type and sub-type) when exiting the program.
Added volumes, times and speeds.
Version 1.0
DIV Calculator is developed using eMbedded Visual C++ 3.0.
Implemented the scientific calculator and the binary calculus.
Implemented the EURO Converter.
And implemented the conversions for temperatures, weights, distances and areas.
Extra functionality planned for future releases:
- The user can define any number of custom currencies, temperatures, weights, distances, areas, volumes, times and speeds
- Check for overflow and underflow when doing calculations
- Help (not just this readme)
- Fancy GUI
- Ability to scroll the stack
- ...
