[RESEND] How to tell Mathematica to use hardware floating point aithmetics

Hello.

Suppose I want to just use hardware floating point operations.

Suppose my hardware uses IEEE754 standard for binary floating point 
arithmetics, and I want all my numerical computation inside mathematica to 
adhere to this only and not to any other in-between software based floating 
point arithmetics (such as significant arithmetics).

Is it enough to wrap each result with N[x,16] ? Or is there a flag/option 
somewhere that one can set once?

thanks,
Nasser
