+0 and -0 are different in IEEE floating point representation. It is information that should be preserved particularly since signed zeros are more important with complex numbers than reals because of branch cuts. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco _______________________________________________ Cython-dev mailing list [email protected] http://codespeak.net/mailman/listinfo/cython-dev
