Should I file a bug report?Yes, probably best to have a record of this. I'm sure the problem is that the equality comparison '==' is done in rectangular form so x1 + iy1 == x2 +iy2 is done by x1 == x2&& y1 == y2. But -0 == 0 so the two are equal. the relational operators used for sorting '<' and'>' compare values in polar form where the different phase angle is important.
Done. https://savannah.gnu.org/bugs/index.php?43313 Dan
