MessageHi George, Obviously, PADS didn't change mathematics (at least in this case), and no one said there was no round off. Other programs simply provided enough digits (precision) to be able to reduce the round off so it has minimal or no significant effect. Obviously, it can be done and works fine.

PADS changed mathematics so there would be no round off. -- George Patrick Tektronix, Inc. Central Engineering, PCB Design Group P.O.
