The only thing it lacks is the list of last calculations performed, and the ability to type in a function in a command line, like one can do in SpeedCrunch. The window is also small, but totally resizeable (buttons as well), and includes portrait/landscape modes. The program is small (~300Kb, and the whole folder ~750Kb), portable, and free. As well as all the other functions, suchs as Statistics, Finance, etc., all in one calculator. It is very, very flexible and configurable, and has so many functions that one doesn't usually find inside a calculator, such as Roman Numerals, Periodic Table, ASCII Chart, Timer/Stopwatch. I had used Calc98 for many years, but had forgotten about it until now.
Operating system: Windows 10 with Razer Synapse keyboard application. After that time we ask you to register the product, free of charge. Experienced behavior: The application appears but the focus is maintained in the window I was before, so I have to alt+tab to speedcrunch, or manually click on it before typing something there.
