question: is there a standard for 'shortest'? about ryu HOT 1 OPEN

Spreadsheets need 'decimal' format for certain areas and 'scientific' for others, depending on user's request or default. I think it is better if ryu can provide this directly than if the programs have to do downstream string manipulation.
I tried and managed to adapt ryu's output to other formats by patching d2s.c and generic128.c ( I didn't need fs2 yet, but it should be possible as well ).
If someone needs this, he can find the code at https://gitlab.gnome.org/GNOME/goffice/-/issues/57, there comment from 2022-05-11.
And if someone has time:
A.) to check that I didn't add any bugs,
B.) if you can optimize it further,
C.) if it's license-legally correct ( enough readmes included, all foreign rights respected, effective disclaimer ),
then he could do me and possibly others a big favor.

from ryu.
