Hello:

I have  a  `Module' of the following type:

         function[x_Real,y_Real]:=
           Module[{z,t,aa,bb,cc,...},
           aa=2*Pi*x-y*3.12;
           bb=x-y;
           ...
           ]

(it is only an example).
I'm not interested in any kind of formal computation, but only in 
numerical computations, much faster. My question is the following.
Should I choose this way:

         function[x_Real,y_Real]:=
           N[
           Module[{z,t,aa,bb,cc,...},
           aa=2*Pi*x-y*3.12;
           bb=x-y;
           ...
           ]
           ]

or is it better this other one:

         function[x_Real,y_Real]:=
           Module[{z,t,aa,bb,cc,...},
           aa=N[  2*Pi*x-y*3.12  ];
           bb=N[  x-y  ];
           ...
           ]

Or maybe anyother thing?. Here my main interest is the 
computation speed.

Thank-you
            Jesus ROJO
