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. 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.

Known Issues:
- 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].
