Standard kind definitions ! wp (working precision) and iwp (integer working precision) are the kinds ! used by default in all variable declarations. ! By default, PALM is using wp = dp (64bit), and iwp = isp (32bit). ! If you like to switch to other precision, then please set wp/iwp ! appropriately by assigning other kinds below. !------------------------------------------------------------------------------!
