| 33 | ! Standard kind definitions |
|---|
| 34 | ! wp (working precision) and iwp (integer working precision) are the kinds |
|---|
| 35 | ! used by default in all variable declarations. |
|---|
| 36 | ! By default, PALM is using wp = dp (64bit), and iwp = isp (32bit). |
|---|
| 37 | ! If you like to switch to other precision, then please set wp/iwp |
|---|
| 38 | ! appropriately by assigning other kinds below. |
