# ![Icon](http://www.menees.com/Images/RpnCalc3.png) RPN Calc

This is an [RPN](https://en.wikipedia.org/wiki/Reverse_Polish_notation) calculator for Windows desktop similar to an old [HP48](https://en.wikipedia.org/wiki/HP_48_series) 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.
