Description
⚖️ Rounding in PostgreSQL isn’t just about trimming decimals—it’s about understanding precision, scale, and how PostgreSQL handles your numbers behind the scenes!
In this tutorial, we dive deep into how NUMERIC(precision, scale) works and how it affects rounding behavior, especially during inserts, updates, or calculations.
💡 You’ll learn:
What precision and scale really mean in PostgreSQL
How values are rounded, coerced, or rejected based on column definitions
PostgreSQL's default rounding method: rounding away from zero
Real-world use cases like pricing, tax rates, and data aggregation
Comparisons with REAL/DOUBLE PRECISION rounding behaviors
How to test and verify your results using INSERT ... RETURNING *
Plus, we explain quirks like rounding ties (e.g. 2.5 → 3, not 2) and how PostgreSQL differs from other DBMSs.
📌 Whether you’re managing monetary data, analytics, or scientific values—knowing how rounding works will save you from major bugs.
