What's the use-case for these? It's not a particularly natural operation, and I've never had a need for a complex "floor" operation, either as a mathematician or as a developer. Do you have an example of real-world code that would benefit?

For those rare cases where this is needed, it isn't that hard to spell out `complex(floor(z.real), floor(z.imag))`, or to write a custom `complex_floor` function.

Also, what type should `math.floor` return when applied to a complex number? `math.floor` of a `float` object returns an `int`, so the analogous operation on a complex number should return a Gaussian integer. But we don't have a Gaussian integer type in standard Python, and it wouldn't be appropriate to add one.
