If Windows already features a built-in calculator, why should you install a new one like CrossGL Surface Calculator?
There are various reasons for this. First, CrossGL Surface Calculator is far nicer than the Windows Calculator. It has a fully scalable interface that can be freely resized without losing any quality. Second, CrossGL Surface Calculator includes also a currency converter. Alright, you can only configure one currency exchange at a time and you have to enter the rate manually, but that's already more than the Windows Calculator can do. Finally, CrossGL Surface Calculator includes some extra settings that let you customize its transparency, digit style and some other details.
CrossGL Surface Calculator is a standard calculator, that is, it doesn’t include any scientific functionality. However it does look cool on the desktop, because its interface resembles a real-life calculator. The only thing you need to take into account is that the buttons to open the configuration menu, resize, rotate or close the app are a bit hidden: you'll need to hove your mouse on the calculator's corners in order to see them.
