I don't understand what you mean by Mathematica not supporting 15 digits. On most platforms, Mathematics supports approximate numbers with roughly 15 digits (unless you force higher precision); it's just that the default display of numbers only shows 6 digits. But you can change the display by wrapping the number with NumberForm. Nonetheless, I wonder what kind of output device you intend to use that can distinguish points apart to that high a precision!

These data represent the latitude an d longitude of world. So, I need to precisely paint those coordinate in a 3D space as a tiny point, perhaps the method ListPoint3D to be used.However, it seems that ListPoint3D does not support morn than 6 significant digits. So, can anyone help me ? > -- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
