No. But given that Lua (reasonably) defaults to double I expect to be

There are better ways to write that, and you should use them...
expecting fractions to silently be dropped is just plain dodgy.

[e.g., = (bit.rshift (0xffff, 8), 0xff) ]

I know this and all the details. Been there, done that.

I already wrote that the concern is about least surprise and coding style. I do not consider using bit.Xshift or math.{round,ceil,floor} everywhere to be especially beautiful nor readable (reviewable, maintainable) code. This undefined, yet unexpected behaving rather leads to mistakes rather sooner than later.
