Mathematica normally displays 6 digits for approximate numbers. To change
this for individual cases use NumberForm to obtain the print precision you
The result will be in machine precision no matter the number of digits
If you want a permanent change in the number of digits displayed, open the
Options Inspector, set the scope to notebook or global and go to Formatting
Options/ Expression Formatting/ Display Options/ Print Precision and change
the number of digits you want displayed.
If you are concerned about precision in your calculations study Section 3.1
Numbers in the Mathematica Book.
And remember that N has nothing to do with display precision, it only
converts exact numbers to approximate numbers.
