Take a complex number n = 3+4j. n.real is taken as 3.0 & n.imag as 4.0 in Python3.  One has to use the int(0 function to get back the parts as integers.  I guess this is a compiler error?

From the documentation: "Complex numbers have a real and imaginary part, which are each a floating point number."

Needing to use int() to convert these floats to integers is not a bug, it's the expected behavior.

Dear Mr SpearThanks for the prompt response & clarification.(in Python) If the real & imaginary parts of numbers you deal with are integers, results of operations (except division)  - like +, -, *, **, - appear with respective integers as real & imginary parts.  In line with these, changes in '.real' & '.imag' may be desirable?
