[Pw_forum] How to show more digits in the results?

[Haibei Huang]

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.
Best regards
Haibei
