Usually based on magnitude alone.
That's why I said the results would be equivalent to the length of 
a point approach. You assume that any point on the same sperical 
locus is equal.  At least on my engineering course :-)


I confess I haven't tried it to see if Python implements cmp for 
the complex type.

>>> c < d
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: no ordering relation is defined for complex numbers
>>>

Apparently not! :-/
