Forth Calculator (RPN) final version

edited November 14 in Share Your Work

I am learning Forth with "Starting Forth" and "Thinking in Forth" books by Leo Brodie.
I need to visualize how works the stack...and then write a processing sketch.

  • Are you trying to create a Forth emulator?

    No. It is only a calculator with an unlimited (almost) stack manipulable with Forth WORDS (dup, drop,...).

  • New functions:
    - complex arithmetic
    - time arithmetic
    I'm working to solve some small bugs :)

  • The sketch is complete :)
    I use it in my daily work.
    Thanks for watching.
