Dear QE developers,<br> I have a very naive question: the variable 'tot_magnetization' is of the type INTEGER. If I understand correctly,<br>nelup+neldw = total number of electrons<br>nelup - neldw = total magnetization.<br>
Since both nelup and neldw are REAL type (could be fractional), why does 'tot_magnetization' have to be an integer? In many real system, the <br>total magnetization is not an integer. <br><br>Thank you.<br><br>Hanghui Chen <br>
