!  DESCRIPTION
!  This module contains integer and real parameters:
!  - kind parameters for single (sp) and double (dp) precision
!  - definitions for pi (3.14...) and compi (imaginary unit)

! wwvv never used
!      this would be a nice place to hold things as pi, twopi
!      and so on

   real(kind=dpkind),    parameter :: pi     = 4*atan(1.0_dpkind)
   complex(kind=dpkind), parameter :: compi  = (0.0_dpkind,1.0_dpkind)
