Will you make chips? I think they are already below 32nm. Confused with um? Sorry, I will not follow this discussion, I am sure the smart PCB developers will do it right. But my feeling is that 32 bit integer is more than enough precision -- if you do it right, at least not too wrong. Using 64 bit is like driving with a tank to your local milk store -- yes there may be benefits, you do not have to watch for the traffic. Its similar to numeric computing/simulations: 1969 they made it too the moon, smart people with 8 bit computers. Today we tend to use largest available precision, just because we have it, and because so we need not to think about the possible (numeric) problems. And please don't forget other architectures, i.g ARM and Mips, not all may support native 64 bit precision. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
