DPR_C: Degrees per radian

Abstract

   Return the number of degrees per radian.

Required_Reading
```
   None.
```

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.
```

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.
```
Exceptions
```
   Error free.
```
Files
