I would have expected integers.

It's the same with strings:

    print(type(math.max("1", "2")))

I'd be very surprised if math.max(a, b) behaved any differently from:

function max(a, b)

    if a > b then return a

    else return b

    end
end

i.e. no changing of types involved (and for that matter, not caring at all about types, as long as the operands have > defined).

(Of course it's slightly trickier since math.max() accepts any number of values except zero, but the principle is the same.)
