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. Regards deetee

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 fkey 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 35. So I tried the first version of rack42 with 615. Regards deetee

Hi!
I proudly present version 2 of RACK42  the spreadsheet application (and more) for the DM42 hardware. What started as an "experiment" became my favor DM42application (even if there is IV42). For more information have a look at https://github.com/zooxo/rack42 or see a short video at https://youtu.be/5BZ6oYsfi6w What's new:

RE: RACK42  A Spreadsheet Application for the DM42
Deetee, you are right to be proud, this is very clever and I think it is also quite novel.
I wish this would get even more interest from forum, even though it does not look like a modernized version of a classic HP calculator (save for the HP35 simili in this app).
