Dear Axel, Thanks for your reply.
The truth is that I was trying to diagonalize a matrix made of a serials of Energies obtained by pw.x, while some of elements in the matrix is quite small (e.g. 10^-7 or 10-^8). Thus, I would like to know how many digits I could trust in Energies. Or at least I should keep the Energies and these small elements in the same scale, say 10^-8. Please let me know if you or anyone know how to change the code showing more digits in pw.x.
