#### Procedure
       SpiceDouble dpr_c ( void )
#### Abstract
       Return the number of degrees per radian.
#### Required_Reading
       None.
#### Keywords
       CONSTANTS
#### Brief_I/O
       The function returns the number of degrees per radian.
#### Detailed_Input
       None.
#### Detailed_Output
       The function returns the number of degrees per radian: 180/pi.
       The value of pi is determined by the ACOS function. That is,

             dpr_c = 180. / acos ( -1. );
#### Parameters
       None.
#### Exceptions
       Error free.
#### Files
       None.
#### Particulars
       When he function is referenced, the value is computed
       as shown above.
#### Examples
       The code fragment below illustrates the use of dpr_c.

          Convert all angles to degrees for output.

                  clock = clock * dpr_c();
                  cone  = cone  * dpr_c();
                  twist = twist * dpr_c();
#### Restrictions
       None.
#### Literature_References
       None.
