With respect to π and the zeros of sin() and cos()? Not really. If numpy.sin(numpy.pi) were to give you 0.0, it would be *wrong*. numpy.sin() is supposed to give you the most accurate result representable in double-precision for the input you gave it. numpy.pi is not π. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
