38! ------------
39!> Standard kind definitions
40!> wp (working precision) and iwp (integer working precision) are the kinds
41!> used by default in all variable declarations.
42!> By default, PALM is using wp = dp (64bit), and iwp = isp (32bit).
43!> If you like to switch to other precision, then please set wp/iwp
44!> appropriately by assigning other kinds below.
