Can I force arbitary precision

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
