Thanks to all my supporters in the competition for the calculator, it is a combined effort of all the forum members through their contributions. Version 4 of the SCalculator is doing all its computation with Complex numbers. Even if you are not interested in such, you benefit by getting all the roots (for example - square root of 16 is 4 but also -4). I also rearranged the controls and corrected some bugs. The manual is readable from the program, launching PWord. One of the controls enables selection between three functions, using the option.txt file to remember your selection. It should be easy to insert another function which you think is important to you through this mechanism. Enjoy ! Edit: Scalculator 5 for device and Desktop, using FgGradientButtons by Filippo. Looks much better.
