z = a + b*i with a, b, elements of R z = r*exp(i*phi) with r, phi, elements of R z = [[a, -b], [b, a]] with a, b, elements of R
This is, in my mind, more questionable: >>> complex(2, 1+1j) (1+1j) >>> >>> print(complex.__doc__) complex(real[, imag]) -> complex number Create a complex number from a real part and an optional imaginary part. This is equivalent to (real + imag*1j) where imag defaults to 0. jmf -- https://mail.python.org/mailman/listinfo/python-list
