How do I ensure the robustness of my Delphi32 application against DRO errors?

To ensure robustness: Thoroughly validate user inputs to prevent invalid data. Implement comprehensive error handling using `try...except` blocks and conditional checks around division operations. Write unit tests to specifically test division scenarios, including edge cases (e.g., zero denominators). Log errors to aid in debugging and identifying potential issues. Regularly review your code for possible division operations and ensure they're properly protected.
