What I meant by "correctly" was that Lua did it correctly where C and
others do it incorrectly, and that mathematicians would disagree with
that assertion.

Well, as I understand it, it was implemented that way in C because
that's how it's done in the hardware. I don't see why math.floor()
makes a good reason when Lua could have just used the C expression a %
b to evaluate the same expression in Lua.
