Hello,
I'm trying to define the number of significant figures used for all
calculations within a module. For example, I'm using the following syntax:

gauss[dig_]:=Module[{$Pre=N[#,dig]&},
         For[k=1,k<=n,k++,
            For[i=k+1,i<=n,i++,multiplier=A[[i,k]]/A[[k,k]]]];
         ...]

I must be able to input any number of digits specified. I'd really
appreciate any help.
Thanks in advance,
Jamie
