There doesn't exist a `normal' definition of < for the complex numbers. For example you would expect that x<y and z<u would imply that x+z<y+u and similar thing for other operators. This is impossible for complex numbers. Now if you use it only for set building then you could relax the constraints and use for example the lexicographical order. -- Piet van Oostrum <[EMAIL PROTECTED]> URL: http://pietvanoostrum.com [PGP 8DAE142BE17999C4] Private email: [EMAIL PROTECTED] -- http://mail.python.org/mailman/listinfo/python-list
