Anything that reduces a complex to a float already... I guess you could argue that behind the scenest hese functions all access .real and/or .imag. >>> float(abs(1+1j)) 1.4142135623730951 >>> float(cmath.phase(1+1j)) 0.7853981633974483 >>> float(cmath.isfinite(1+1j)) 1.0 -- Keeping medicines from the bloodstreams of the sick; food from the bellies of the hungry; books from the hands of the uneducated; technology from the underdeveloped; and putting advocates of freedom in prisons.
