34! ------------
[1682]35!> Standard kind definitions
36!> wp (working precision) and iwp (integer working precision) are the kinds
37!> used by default in all variable declarations.
38!> By default, PALM is using wp = dp (64bit), and iwp = isp (32bit).
39!> If you like to switch to other precision, then please set wp/iwp
40!> appropriately by assigning other kinds below.
