Portable TabbyCalc

Portable TabbyCalc is a small software application whose purpose is to help you work with a mathematical expression calculator. It can be deployed on all Windows versions out there.

Portable running mode

This is the portable version of TabbyCalc which makes it an ideal candidate for being stored on USB flash drives or other devices. You can gain access to its features by simply opening the executable file because you do not have to go through an installation process.
In addition, you may run it without being an administrator. The tool does not leave entries on the target PC so you can get rid of it using a quick deletion task. It actually saves the configuration settings on the storage device.

Simple looks

The GUI looks straightforward and embeds only a few configuration settings which are easy to decode. It sports a minimalist display that reveals all supported functions directly in the main window.
Unlike other calculators that embed a virtual keypad directly in the main panel, Portable TabbyCalc does not offer support for a keypad. It gives you the possibility to input the numbers via your keyboard. The result of eliminating the keypad from the interface is a clean and simple environment where you can focus solely upon the calculations.

Supported calculations

Portable TabbyCalc gives you the possibility to work with various functions, such as absolute value, arccosine, arcsine, sine, cosine, square root, hyperbolic tangent, and hyperbolic arctangent.
In addition you are allowed to perform conversions from binary numbers to octal or hexadecimal, decimal numbers to binary, Fahrenheit to Celsius, grad to degree, liters to quarts, hexadecimal to binary, pounds to tons, yards to meters, as well as other parameters. The results can be copied to the clipboard.
A few configuration settings help you set the color of the background, hide the list with functions from the calculator’s display, clear the entire screen with a single click, adjust the text in terms of size and font, and keep the calculator on top of other windows.
Tests have pointed out that Portable TabbyCalc carries out a task quickly and without errors. It remains light on system resources so it does not affect the overall performance of the PC.

Final remarks

All in all, Portable TabbyCalc accommodates a handy suite of features for helping you perform math calculations and conversions, and can be configured by rookies and professionals alike.
