Question: Rounding numbers

restart:

a:=0.0000000000000000000000213123123;

evalf[3](a);

I think the above is the same as if I were to change the precision tab, to display 3 decimals.

Is there a way to ask Maple to display it as  (printf(  "%3.3f",a);)

0.000

But I want this as a standard Maple ouput.

and I am not just working with a single scalar, I need something that works for a Vector, Matrix, and perhaps, in general.

 

Thanks,
