So I suggest:

1. Methods floor and ceil for complex object.

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.
