For Sage's complex types, you can do. sage: a = CDF(1,2) sage: a 1.0 + 2.0*I sage: x, y = a sage: x 1.0 sage: y 2.0 (Works for CC as well.) Otherwise, z.real, z.imag is probably going to be as fast as you can get, and there's no need to define a function, you could just write sage: a = complex(3,4) sage: x, y = a.real, a.imag - Robert -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
