In modern database systems , functions are not just tools—they define how data is processed, transformed, and controlled. In a GBase database , two powerful concepts come together: Precise numeric control with TRUNCATE Flexible function extensibility via modules (Datablade) 👉 Together, they show how GBase balances accuracy and flexibility . 🚀 1. Precision First: The Role of TRUNCATE In many systems, developers default to: SELECT ROUND ( 1234 . 235 , 2 ); Enter fullscreen mode Exit fullscreen mode ` 👉 Result: text 1234.24 But rounding introduces approximation . Using TRUNCATE Instead sql id="truncate_core_example" SELECT TRUNCATE(1234.235, 2); 👉 Result: text 1234.23 ✔ No rounding ✔ No value distortion ✔ Fully deterministic ⚙️ 2.…
