Rechner

Rechner is a small software application developed specifically for helping you perform basic mathematical calculations straight from the comfort of your desktop.

After a fast and basic installation process where you only need to follow the preset steps in order to complete the task, you are welcomed by a clean and intuitive layout. A help manual is not included in the package. However, you can venture into setting up the math parameters on your own because they look easy to decode.

Rechner offers you the possibility to carry out several simple mathematical operations, like addition, subtraction, division, and multiplication. Numbers can be added only via the virtual keypad (you cannot input them via your physical keyboard).

You are given the freedom to paste numbers from the clipboard directly in the main window and copy the results to the clipboard so you can paste them in other third-party software programs.

Tests have demonstrated that Rechner carries out math calculations on the fly and without errors. It is not a resources hog so you may keep it running in the background without having to worry that it hampers the overall performance of the computer.

On the downside, there’s no support for advanced features so you cannot perform diverse trigonometric functions, such as percentage and square root of a number, sine, cosine, tangent, and cotangent, keep a history with previous calculations, as well as export the results to a plain text file on your computer, just to name a few suggestions.

To sum things up, Rechner proves to be a simple math calculator that comes with support for basic options. It is suitable especially for less experienced users or students who need to check their homework.
