## Numerical Range Validation

Numerical Range Validation is the process of ensuring that input values or calculation results fall within expected and safe bounds. In financial derivatives, this involves checking that prices, interest rates, or collateral amounts are not negative, zero, or excessively large.

By enforcing these bounds, developers prevent the protocol from processing invalid data that could lead to incorrect liquidations or pricing errors. This validation is a critical layer of defense, often implemented at the entry point of a function or before committing state changes.

It protects the system from both accidental user errors and malicious attempts to manipulate market mechanisms. Proper range validation is essential for maintaining the stability of financial systems and ensuring that the protocol operates within its intended economic parameters.

It is a simple yet powerful technique for enhancing the robustness of smart contracts.
