Floor and modulus operators (// and % respectively) are not allowed to be used on complex number in Python 3.x. However, these operations are defined for complex numbers in Python 2.7.x
>>> x=9+2j >>> y=2+1j >>> x%y Traceback (most recent call last): File "<pyshell#2>", line 1, in <module> x%y TypeError: can't mod complex numbers.
>>> x=9+2j >>> y=2+1j >>> x%y (1-2j)
Modulus of complex number operands returns their floor division multiplied by denominator
>>> x-(x//y)*y (1-2j)
