[docs] [issue40269] Inconsistent complex behavior with (-1j)

Serhiy Storchaka added the comment: The Imaginary type could help to solve other "gotchas". For example, in Python

...

...

complex(0, float('inf')) * 1 (nan+infj)

But in C++ you will get the real component 0, because multiplication of complex and real numbers is component wise. With the Imaginary type we could get that 1j * x == complex(0, x) for all float x, including infinity and NaN. Returning to the repr, the other way to correctly represent the repr of complex(-0.0, 1.0) is writing it as "-(0.0-1j)", but it looks unnatural to me. ---------- _______________________________________ Python tracker https://bugs.python.org/issue40269 _______________________________________
