RPN Calculator

Computers have extraordinary computation power, and are widely used to deliver accuracy and fast results in calculus. Windows puts a default calculator at your disposal, which also comes with an advanced component. Needless to say that you can rely on third-party applications, and RPN Calculator is a suitable example in this regard.

Intuitive design for quick understanding of functions

On the bright side of things, you don’t have to go through a setup process to make it work, so it’s possible to use it directly from a thumb drive and on other computers than your own. Note, however, that .NET Framework is a mandatory component for functionality, so you need to make sure it’s on the computer you decide to use.
As the name might suggest, the application is specially designed for Reverse Polish Notation operations. The interface consists of an organized layout, with a numerical pad in plain sight, which is also equipped with several operation buttons. A separate section is there to help you save operators and functions.

Define variables and process equations

Apart from regular operations, the application is capable of solving some more complex queries, such as abs, cos, ceil, sin, sqrt, tan, and more. Functions are also supported, but you might need to define some variables at first. In fact, this is a mandatory step, because the application isn’t meant for simple calculus.
Several preset equations can easily be selected from a dedicated menu, such as cube, square, and area of a rectangle. There’s a log window so you know whether or not operations result in error, while also showing results. Sadly, these can’t be saved to file, so you need to manually copy them where needed.

In conclusion

All things considered, we can state that RPN Calculator can help you perform various advanced equations with ease. A decent variety of operations are supported, while the log window helps you stay on track with everything going on.
