Hi Giorgio,
I asked the same question a few months ago and I got some answers.
Here is what I am using (Mathematica 5.2, but works also with 6):
nf2[n_]:=NumberForm[n,{16,2},NumberPadding -> {"", "0"}];
This will give you 2 digits, if you need something different change {16,2}
to what you need.
In Mathematica 6 you can specify the same thing in
Edit -> Preferences -> Appearance -> Numbers -> Formatting and change the
"Display precision"
But you have to change this every time you want to modify your output.
Hope this help,
Robert

hello. My question is very very easy.
I have got a variabile as "a" and i want to print his approximated
value with n decimal digit.
a=1.56068376362920545943;
Print["The value is : ", 1.6];
or
Print["The value is : ", 1.56];
Is there anyone who can help me ?
thanks
Giorgio
