Real Big Calculator
Real Big Calculator is a small widget that displays a large calculator on your desktop, so you can quickly perform mathematical operations. It is easy to install and set up.
After a brief installation operation, you are greeted by a very small window that you can move to any position on the screen, with the help of the mouse cursor.
Clicking it reveals the calculator whose interface resembles the look of an actual pocket calculator. Unfortunately, Real Big Calculator does not integrate any options of its own.
But, thanks to the default settings provided by the operating system, you can open the context menu to make some adjustments. Therefore, you can set the frame's opacity level between 20% and 100%, as well as make it stay on top of other windows.
Real Big Calculator does not interfere with the runtime of other currently active processes, since it runs on a very low quantity of CPU and system memory. It has a good response time and worked well during our evaluation, without causing the operating system to hang, crash or pop up error dialogs. To sum it up, Real Big Calculator is a nice widget for users who are looking for an alternative calculator to work with.
