Solway's Expression Calculator

Solway's Expression Calculator is a tiny and accessible piece of kit that comes loaded with few yet powerful options to help you calculate mathematical expressions using functions and symbols which aren't available in common calculators.
It supports logarithms, trigonometry, inverse, square, square root, and power, among others. This type of software comes in handy not only to math students and teachers, but also to casual users.

Clear-cut installer and interface

Installing Solway's Expression Calculator is a fast and uncomplicated task that doesn't need special attention, since the wizard has only familiar options.
As far as the interface goes, the program opts for a small window with a dialog box dedicated to entering math parameters, two buttons, and a couple of options with tick boxes.

Math syntax as in programming languages

Before attempting to input expressions, you can consult the help area to discover all functions supported by Solway's Expression Calculator, along with a few examples concerning syntax.
For example, you can use pi, sqrt() for square root, arcsin(), tan(), arctan(), fact() for factorial numbers, and so on. These should be familiar to users who have tinkered a bit with programming languages, since Solway's Expression Calculator adopts the same syntax as the mathematical library.

Calculate simple and complex math expressions

It's possible to enter simple expressions like 2*2, or more complex ones like pi*(2*sqrt(cos(23))/4)+sqr(2^2.1). What's more, you can enable thousands separators and ask the application to display only 2 decimal places accuracy.
The mathematical expressions are instantly calculated with one click as well as automatically recorded to history and added to a drop-down list, which means they can be later selected, edited and recalculated. The result can be copied to the Clipboard. There are no other notable features available here.

Evaluation and conclusion

As expected, CPU and RAM consumption was minimal in our tests, so the software tool didn't hamper system performance. It performed calculations instantly and delivered accurate results. On the other hand, it could have included a complete list with math functions to be studied in detail, and maybe it could have implemented buttons for quickly inserting them into expressions.
Nevertheless, Solway's Expression Calculator delivers a fast and effective solution to calculating simple and complex mathematical expressions, and it can be seamlessly used by anyone.
