These are two different "sqrt": the first one is a sage specific function, the second one is from numpy. it's just that numpy's sqrt(2) produces something (a float64 type) which makes troubles with the part from sage (which is not of type "complex", but "sage.rings.complex_number.ComplexNumber") here is a more isolated example: import numpy as np 1j / np.float64(2) which gives 0. note: type(1j) <type 'sage.rings.complex_number.ComplexNumber'> Harald -- You received this message because you are subscribed to the Google Groups "sage-support" group.
