Description
⚠️ Warning for PostgreSQL users working with financial data!

In this video, we break down why casting FLOAT to MONEY in PostgreSQL is a bad practice — and how it can silently affect the accuracy of your financial records.

💡 You’ll learn:

What happens when you cast FLOAT to MONEY and why it's unreliable.

How floating-point arithmetic introduces rounding errors.

Why these small inaccuracies can compound in invoices, totals, and reports.

Safer alternatives: using NUMERIC or DECIMAL for precise monetary calculations.

📉 Real-world scenario: A float-based price like 1234.5678 might look fine — but when cast to MONEY, it can result in truncated or incorrectly rounded values that don’t match your actual transactions.

✅ This tutorial shows the do's and don'ts of data type conversion, especially for apps involving pricing, billing, salary, or any sensitive currency logic.

🧠 Pro Tip: Always store and calculate financial values using NUMERIC or DECIMAL to preserve precision — and only convert to MONEY for formatted output, if necessary.

📌 Watch till the end for a side-by-side demo of how FLOAT, NUMERIC, and MONEY behave differently.
