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