CalKul

An RPN calculator written in C#. For the moment only handles doubles, strings, booleans and a few operators.

Why?

For now? Just for fun. Also to have a simple calculator with some RPN/RPL capacity in PowerShell or Bash.

Tips and tricks

Write simple RPL programs by enclosing the program with §. (This works the same as the << >> characters in Hp calculators.)

Store programs in variables by using "programname" sto. Like this:

§ if 100 < then "Sad" else "Great" end §
"trmpf" sto
20 trmfp        [output -> Sad]
120 trmpf       [output -> Great]

The calculator has, besides the maths, some fun operaors/functions like rand, date, beep, wait, if-then-else-end and setconfig. More to come. It also has variables (that you can store programs, bools, strings and doubles in for the moment) but these are not persisted between sessions.

Config settings

• windowwidth (default: 40)
• windowheight (default: 20)
• showdatatypes (default: 1 -> on)
• showlinenumbers (default: 1 -> on)
• stackrows (default: 10)

Todo

• Move from supporting only double to supporting objects on stack
• Add tan, rand, ==, <, >
• Add asin, acos, atan, 1/x, !, ln, e^x, 10^x and log
• Add more RPL words for stack manipulation
• Add more RPL words for conditionals
• Do crazy stuff with URLs
• Test other user interface?
• Add variables
• Add variable persistence

Ideas for the future

Lots. No promises though.

• Sound
• wget/curl like functionality
• Supporting HTTP verbs
• Supporting images
• DSL?
• Bash/PowerShell command support
• Supporting all kinds of .NET types for Windows instrumentation and other craziness
