This is an RPN calculator for Windows desktop similar to an old HP48 calculator. It supports binary/octal/decimal/hexadecimal values, large integers, fractions, doubles, complex numbers, DateTimes, and TimeSpans.
RPN Calc is a WPF app, and it requires either the .NET Framework or .NET Core. There is no installer. Just download the zip, extract it to a folder, and run RpnCalc.exe.
