In theory I've implemented arbitrary-precision unsigned arithmetic in Lua!

Feel free to recommend tests which'll actually use multiple digits... Thankfully it'll be a while before I'm ready to integrate this...

Or point me towards how to do bitwise-operations in Lua? I'm surprised Lua omitted these operators!

It sounded fun to implement. I think I'll tackle keyboard navigation.

Maybe something like "1000 factorial / 999 factorial"?

Required conversions both ways, does large division and the result is a simple 1000.

@kirtai Yeah, that could do it!

@alcinnz Lua from version 5.3 onwards has built-in bitwise operators. If you are using versions 5.1 and 5.2 (later versions also work), you can use the BitOp C extension module. Or you can use LuaJIT which comes with BitOp built-in.

@smlckz O.K., so much online was saying otherwise... I'll try it!
