Validated numerics

Validated numerics is a computational technique used to ensure the accuracy and reliability of numerical results in scientific computing. It incorporates methods and frameworks to formally verify and validate the results of numerical computations, particularly when dealing with floating-point arithmetic, which can introduce errors due to its inherent limitations and approximations. Key aspects of validated numerics include: 1. **Bounding Enclosures**: Instead of producing a single numerical result, validated numerical methods often return an interval or bounding box that contains the true solution.
