Description
In this video (Part #43 of the PostgreSQL Full Playlist), we take a deep dive into Numeric Data Types in PostgreSQL—an essential concept for every backend or data engineer. 🚀

You’ll learn how to handle real-world data like prices, tax rates, measurements, sensor data, population counts, and financial transactions using:

Integer Types: SMALLINT, INTEGER, BIGINT
Fixed Precision: NUMERIC, DECIMAL
Floating-Point: REAL, DOUBLE PRECISION
Auto-Increment Types: SERIAL, BIGSERIAL
Special values: Infinity, -Infinity, NaN

We also explore precision, rounding behavior, and common pitfalls—along with RETURNING clauses for instant verification. No more boring examples—every use case in this video is practical and relatable. 🧮💰
