New submission from Eric Wieser <wieser.e...@gmail.com>:
Python distinguishes signed zeros by their repr: # floats >>> 0.0 0.0 >>> -0.0 -0.0 # complex >>> complex(0.0, 0.0) # A 0j >>> complex(0.0, -0.0) # B -0j >>> complex(-0.0, 0.0) # C (-0+0j) >>> complex(-0.0, -0.0) # D (-0+0j) However, only one of these `complex` reprs round-trips: >>> 0j # ok 0j >>> -0j # doesn't round-trip (-0-0j) >>> (-0+0j) # doesn't round-trip 0j >>> (-0-0j) 0j ---------- components: Interpreter Core messages: 374864 nosy: Eric Wieser priority: normal severity: normal status: open title: Repr of complex number with signed zero does not roundtrip versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41485> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
