2.0 is low precision. try N[Pi+2,1000]. You could try reading the
manual.

Using N[] that way seems to be the same as using SetPrecision:

In[43]:= r = N[Pi + 2, 1000];
Precision[r]
Out[44]= 1000.

In[45]:= r = SetPrecision[Pi + 2, 1000];
Precision[r]
Out[46]= 1000.

What exactly is the difference you show by using N[] vs. SetPrecision[] as I
said?
