45 | !> Standard kind definitions |

46 | !> wp (working precision) and iwp (integer working precision) are the kinds |

47 | !> used by default in all variable declarations. |
---|
48 | !> By default, PALM is using wp = dp (64bit), and iwp = isp (32bit). |
---|
49 | !> If you like to switch to other precision, then please set wp/iwp |
---|
50 | !> appropriately by assigning other kinds below. |
