mobile default iconCalc4M for Java Publisher's description

Scientific calculator with trigonometric and logarithmic functions, conversions, hexadecimal/binary/decimal conversion and calculation, four memories and constants. Support for both handset and touch screen

This is a scientific calculator for mobile phones. It is configurable and contains most of the normal functions such as trigonometric and logarithmic functions, conversions, constants, memories and binary, octal and hexadecimal notation.

If fully supports both touch screen and non touch screen models, you may use the buttons, if you have a touch screen you may also click on the screen. It automatically adapts to the screen size and phone model standards.

It is easy but still fast to use and with lot of functionality. One important thing to note is that most buttons have two functions. Press and hold down the key to access the "secondary" function.

The following settings are configurable:
* display a welcome screen or not
* display the call stack or not
* automatically return to the basic arithmetic screen or not
* use full screen mode or not
* use nice looking button texts or "safe" texts that works in any mobile
* two different keyboard layouts
* calculation font size
* default number format (sci/eng/default)
* type of "long button press" notification

For more screendumps of the calculator, see http://www.hellebo.com/Calc4M.html

For the calculations, the library ral.Real is used, see http://real-java.sourceforge.net/Real.html
