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