div for complex data does not behave expected

[ruoting0103]

from fxpmath import Fxp
x = Fxp(2j, dtype = 'fxp-u4/0-complex')
x/2

the result is fxp-u4/0-complex(0j) rather than 1j

i could solve the problem by adding x.config.op_method = 'repr'

is there any other way to make it work like 2j/2 ? thanks

Clearly, it's a bug!

I did a debug and the problem is that a floordiv with a complex number doesn't work in python nor numpy

j2 // 2 # raise TypeError: can't take floor of complex number.

np.array(2j) // np.array(2) # result = 0j

The raw method is used bay default in Fxp operation to assure precision, when you use repr the operation is performed using a truediv (/).

In other way, if you use multiplication and give a fractional bit the operation is performed well, but I don't think this is a workaround:

x = Fxp(2j, dtype = 'fxp-u4/1-complex')
x * 0.5

fxp-u4/1-complex(1j)

A special method should be implemented for complex division (raw op_method). It would be included in next release!
