RE: tabulate an expression in arbitrary precision

Something like this:

Table[{x, Erf[SetPrecision[x, 40]]},
      {x, {.5, 1., 2., 5., 10., 20.}}] // TableForm


You will probably get a better answer from those who regularly do high
precision calculations.

Hi, 
I am new to MATHEMATICA, and I am looking for advice. 
I have access to MATHEMATICA 6.0.
I need to tabulate values of a certain expression involving error function
Erf[x], for a number of x values.
The problem is that I need to do these calculations in
arbitrary precision (that is I want to be able to control
the number N of significant digits). Can anybody show me some examples of
how this might be done? I stress I know
nothing about MATHEMATICA. I want the results to be displayed and saved in
the form of a table having two columns, where the first column contains x
values, and
the second column contains the corresponding values of the expression, with
all N significant digits.

Leslaw
