Re: How to increase Working Precision?

Again, I suggest you read the manual, and in particular note the
difference between the Mathematica notions of precision and accuracy.

A very precise value for pi is 3.15000000000000000000000000000000
which happens not to be very accurate.

In fact the notions of Precision and Accuracy in Mathematica are, in
my opinion, rather bogus. Numerical analysts have the well-defined
notions of relative and absolute error, as well as precision. These
do not correspond to Mathermatica.
