Statistics problem  numeric solution to Gaussian CDF.
Posted:

Does anyone have (or know how to solve) a numeric approximation good to about 31 decimal places for the Gaussian CDF. i.e. Given a standard normal curve, we must integrate the PDF to determine the cumulative probability for a zstatistic of, say 12.0 (very high).
There is a very heavily published approximation that is good to about 6 decimal places (zstatistic of about 4.3), but I need more precision.
Help!......
