The meter was originally defined to be 1e-7 of the distance between the equator and the North pole, so 1 degree of latitude is roughly 1e7 m/90 ~ 1e5 m. 1e-16 * 1e5 = 1e-11, 1/10th of an Ångström. -- 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 -- http://mail.python.org/mailman/listinfo/python-list
