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. David Park djmpark at comcast.net http://home.comcast.net/~djmpark From: Leslaw Bieniasz [mailto:nbbienia at cyf-kr.edu.pl] 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.
