Description
😲 Did you know PostgreSQL can round to the left of the decimal point?
In this exciting tutorial, we explore a hidden but powerful feature in PostgreSQL: negative scale in NUMERIC(p, s) types.
This feature lets you round values not to the right (like cents), but to the left—like nearest 10s, 100s, 1,000s, or even lakhs and millions.
📚 Here's what you'll learn:
What a negative scale means in a NUMERIC(p, s) column
How PostgreSQL rounds values like 15432 to 15000 or 99000
Real-world use cases: rounding financial reports, estimates, budget summaries, and anonymized data
How this feature works under the hood, and how it’s different from regular rounding
Edge case examples using NUMERIC(2, -3) and what precision still controls
How to test values using INSERT ... RETURNING *
🔍 This feature is especially useful for reporting dashboards, government data, and analytics, where high-level approximation is needed.
✅ Available since PostgreSQL 15+, this feature adds a new layer of numeric control.
