From Marco Maroni:
It's a simple mathematical calculator, but with a useful peculiarity: it is positioned on the taskbar, that area of the desktop where the list of the open programs appears (generally on the bottom of the screen), so that it doesn't cover the opened programs, making the calculation more practical. It supply basic mathematical functions: sum, multiplication, division, subtraction, percentage, square root.
What's new in this version:
Windows 7, 8, 10 x64 platform support.
