Calculator

Calculator is a tiny widget which contains a virtual calculator. It can be easily accessed from the sidebar on the desktop, and used by common users.

The interface of the app is based on a small frame which you can move to any position on the screen, with the help of the mouse cursor.

You can add and substract numbers, use fractions and percentage, along with the square roots, Memory Add, Memory Recall and Memory Clear functions.

From the Settings screen, you can make several adjustments to the widget. For example, you can pick the measurement unit (radians or degrees) and use digit grouping, customize the background color and memory, clear, operator, number, equals and extra buttons. All fields can be restored to their default values at any time.

With the courtesy of the operating system, you may also increase the size of the frame, make it stay on top of other windows, as well as adjust its opacity level between 20% and 100%.

The lightweight app does not put a strain on the computer's resources, as it runs on a very low amount of CPU and system memory. It has a good response time. Calculator did not cause us any difficulties during our tests, since it did not hang, crash or pop up error notifications. Thanks to its overall simplicity, Calculator can be handled even by users with no experience in software apps.
