Historically, parts of the C++ code were actually built in C. However, the calculator is complex both in the way it was coded over the years, as well as the advanced functions it has.įirst, it’s built entirely using standard C++ 11 and C++/CX, with a calculation engine that dates back from 1995. Of course, that is a good UX choice Microsoft made as most uses of the calculator are rather simple ones. The simple initial UI you see upon launch can be deceiving. The Windows Calculator is an interesting and not-so-simple piece of software. Windows 10 – well, just open it on Windows 10 ?.
