Hi, list.
I've tried using the xdecimal library included with LuaMetaTeX and I have
some remarks:
1. Shifts are decimal, not binary: 145 >> 1 gives 14.
2. Integer division (//) is not implemented. Is that by design?
3. Following 2, what would be the way to handle integer division,
remainder... for large numbers?
Thank you in advance.
Best regards,
Jairo

this is how decnumber defines shift: digits

I forgot to mention ceil and floor, just in case they can be implemented. I
have a long list of examples, so testing will be easy. Thank you very much.
Best regards,
Jairo :)
