| 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. |
