Just like this? (Lua 5.3.3)

local t = { [1] = "test" }
print(math.type(next(t))) --> integer
t[1.0] = "test"
print(math.type(next(t))) --> integer
t[1] = nil
t[1.0] = "test"
print(math.type(next(t))) --> integer

As well:

local t = { [2^62] = "test" }
print(math.type(next(t)), math.type(2^62)) --> integer float

I'm not sure what your point here is.
