The 32/64-bitness of your platform has nothing to do with floating point. Nothing discussed in this thread is platform-specific (modulo some minor details about the hardware FPU, but that should be taken as read). -- Robert Kern _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
