If an invalid operator is entered, the program provides a clear error message.
Key Features:
- Supports addition, subtraction, multiplication, and division.
- Handles invalid operator inputs gracefully.
- Accepts floating-point numbers for precise calculations.
- Outputs results rounded to three decimal places.
Ideal for beginners learning Python or anyone needing a straightforward calculator tool.
