#### Procedure

       dpr_c ( Degrees per radian )

       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.
