## Rounding Bias

Rounding bias is a systematic error that occurs when numerical values are consistently rounded in a specific direction, such as always rounding down. In large-scale financial systems, these small errors can accumulate into significant discrepancies over millions of transactions.

If a protocol rounds down interest payments or fee distributions, it can result in substantial wealth transfers over time. This is a critical concern for auditing and maintaining the integrity of financial data.

To mitigate this, developers use unbiased rounding techniques, such as rounding to the nearest even number, to ensure that errors cancel each other out. Identifying and correcting rounding bias is essential for the long-term sustainability of decentralized economic models.

It represents a subtle but powerful risk in automated systems.
