It supports binary/octal/decimal/hexadecimal values, large integers, fractions, doubles, complex numbers, DateTimes, and TimeSpans.\n\nRPN 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.\n\n![RPN Calc](http://www.menees.com/Images/RpnCalc3Screen.png)\n\n## Data Entry\n| Data Type | Entry Value | Display Value | Entry Format |\n| --- | --- | --- | --- |\n| Binary | #10101b | # 10101b | HP-style using # prefix and b suffix |\n| Hexadecimal | #ABCDh | # ABCDh | HP-style using # prefix and h suffix |\n| Hexadecimal | 0xABCD | # ABCDh | C-style using 0x prefix |\n| Fraction | 1_2 | 1/2 | Underscore-separated numerator and denominator |\n| Fraction | 1_3_4 | 1 3/4 | Underscore-separated whole part, numerator, and denominator |\n| Complex | (1,3) | (1,3) | Rectangular |\n| Complex | (2,@45) | (2,@45) | Polar using the current angle mode (e.g., degrees or radians) |\n| DateTime | \"9/11/10 4:51pm\" | 9/11/2010 4:51:00 PM | Double quoted date/time using the current culture's formatting rules |\n| TimeSpan | 19:01 | 00:19:01 | -d.hh:mm:ss.fff where the sign, days, hours, and milliseconds are optional |","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmenees%2Frpncalc","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmenees%2Frpncalc","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmenees%2Frpncalc/lists"}
