So I used set precision function when using the cout to print the
solution vector.
With setprecision, the values are printed accurately to machine precision.
However, I was still unable to write the values accurately upto machine
precision, to a vtk file.
Did you use .setprecision(...) also on the stream that you give to
data_out.write_vtk()? You need to set the precision separately for each
stream on which you want to output.
