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
