Hi, I am doing a little numerical calculation on Mathematica. The problem is that if I input a number as 1.7341421*^-9, mathematica automatically trim it to machine precision number. Yes, I can force the number as 200 digit precision, but efficiency sacrificed. And I have to try different precision to make sure that it runs as fast and as accurate. My question is: can I force an arbitary precision so that I could throw the precision and accuracy problem to mathematica? thanks -- Wan Kuang Electric Engineering - Electrophysics University of Southern California Los Angeles, CA 90007
