RACK42 - A Spreadsheet Application for the DM42
Hi!

I proudly present RACK42 - a small and powerful RPN spreadsheet application for the DM42 hardware.

For more information have a look at https://github.com/zooxo/rack42
or see a short video at https://youtu.be/_lt0Zoqh0og

Thanks in advance for any comment, suggestion or bug to make RACK42 faster, more versatile, stable and intuitive.
Particularly I'm planning to expand the mathematical power of RACK42 (ie conditions, probabilities, hyperbolics, logic, base) and improve the handling (ie copying cell ranges, fixed cell references, more graphic charts) - so I'm curious which features are needed most to build in.

Looks fun.

I see that rows are 15 and columns 6. How did you get to those dimensions ?

To display a number with 'sufficient' precision (what is sufficient?) you need 8 or 9 digits. With an easy 'readable' (what is readable?) font you can display on the screen 3 numbers (cells) in a line.

The central part of the display (screen less status line less edit line less f-key line) allows 5 rows with this readable font.

And finally - as rack42 demands to be small and clear - the number of rows should be a low multiple of 3|5. So I tried the first version of rack42 with 6|15.
