Mini Calculator

As the name of this piece of software implies, Mini Calculator is a lightweight app that allows you to perform mathematical calculations on a small calculator. It can be easily handled by individuals of any level of experience.
This is a portable tool, so installing Mini Calculator is not necessary. It means that you can place the app on an external device (like a USB flash drive), place it on any computer and directly run its executable file.
What is more important is the fact that the Windows registry is not altered in any away. Moreover, no leftover items can be found after program removal.
The interface is based on a small and dull window that resembles a classic pocket calculator. Besides allowing you to perform basic mathematical operations, Mini Calculator also has a "Scientific" mode that can be enabled by opening the context menu. Thus, you can use complex functions like square root, pi, sin, cos and percentage.
Furthermore, you can display a strip and copy or save the esults to a plain text document. But you can also set Mini Calculator to minimize to the system tray and to stay on top of other applications, as well as access the "Options" area to save the window's position and program state.
The simplistic tool requires a low amount of CPU and system memory and has a good response time. We have not encountered any problems throughout our testing; Mini Calculator did not freeze or crash.
