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
2. Integer division (//) is not implemented. Is that by design?
i'll add that one
3. Following 2, what would be the way to handle integer division, remainder... for large numbers?
i'll add a % b
Thank you in advance. better first do the testing

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 :) El lun, 28 de dic. de 2020 a la(s) 10:39, Hans Hagen (j.hagen@xs4all.nl) escribió:
