Common error types include rounding mistakes, hallucinated numbers, and logic drift over time. Practical detection methods include a 5-minute weekly spot check comparing AI outputs to manual calculations, and automated regression testing with 50+ known input-output pairs. Distinguishing prompt engineering issues from true model-level failures is key before investing in fixes. Real-world examples from FinTech, SaaS, and e-commerce illustrate the financial impact of unchecked AI math errors. ## Full article daily.dev links to this article rather than hosting it.
