What about a "SCI ALL" format?

Thank you for this hint. Yes, this works... but (1) only for a temporary number display, (2) only for ENG and not for SCI and (3), most important, only on calculators that feature such ←ENG and ENG→ keys.

I am thinking of a normal, permanent display mode so that numbers are directly shown as described above.
Maybe this in as idea for a custom firmware project. ;-)
