Abstract


   CSPICE_HALFPI returns the double precision value of the constant PI/2.0.

   For important details concerning this module's function, please refer to
   the CSPICE routine halfpi_c.

I/O

   
   Given:
   
      No input required.
   
   the call:
   
      halfpi_double = cspice_halfpi()
   
   returns:
   
      A double precision scalar, the value of half the value of pi.
   

Examples


   Any numerical results shown for this example may differ between
   platforms as the results depend on the SPICE kernels used as input
   and the machine specific arithmetic implementation.

   
      print, cspice_halfpi()
