### Key Changes and Considerations: 1. **Input Validation**: Added a check to handle negative input numbers, as the square root of a negative number is undefined in real mathematics. 2. **Precision**: The `precision` parameter is now a required argument in the C implementation, as C does not support default argument values like Python does. 3. **Floating-Point Operations**: Used `fabsf` for floating-point absolute value calculation to match the type signature of the function. 4. **Division and Multiplication**: Used `2.0f` to ensure floating-point division and multiplication to maintain precision. 5. **Error Handling**: Returned `NAN` (Not a Number) for negative input numbers and printed an error message. 6. **Example Usage**: Provided a `main` function to demonstrate the usage of the `my_sqrt` function.
