Abstract

   CSPICE_DPR returns the value of the constant 180/pi which represents
   the number of degrees of arc per radian.

I/O

   The call:

      [dpr] = cspice_dpr

   returns:

      dpr      the number of degrees per radian: 180/pi.

               [1,1] = size(dpr); double = class(dpr)

               The value of pi is determined by the acos function. That
               is,

                     dpr = 180.0 / acos ( -1.0 );

Parameters

   None.

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.

   1) Compute the number of degrees of arc per radian.

      Example code begins here.


      function dpr_ex1()

         fprintf( 'Degrees per Radian: %10.7f', cspice_dpr )


      When this program was executed on a Mac/Intel/Octave6.x/64-bit
      platform, the output was:


      Degrees per Radian: 57.2957795
