Convert radians to degrees and degrees to radians.
Uses Go's built‑in math facilities:
- math.Pi provides a precise value for π.
- The conversion formulas follow the standard mathematical relationships:
degrees = radians * (180 / math.Pi)
radians = degrees * (math.Pi / 180)
The program demonstrates clear structure:
- Small, focused functions
- Descriptive names
- Comments explaining intent
