python - How to round up a complex number?

Question

How can I round up a complex number (e.g. 1.9999999999999998-2j) as 2-2j?

When I tried using

print(round(x,2))

it showed

Traceback (most recent call last):
  File "C:Python34FFT.py", line 22, in <module>
    print(round(x,2))
TypeError: type complex doesn't define __round__ method

Answer 1

Round real part and imaginary part separately and combine them:

>>> num = 1.9999999999999998-2j
>>> round(num.real, 2) + round(num.imag, 2) * 1j
(2-2j)
