Advanced DAX Tutorial | Module 11 | DAX Rounding Functions & Practical Examples in Power BI
Are your DAX totals slightly different from expected business numbers?
Learn how rounding logic impacts financial accuracy and time-based calculations in Power BI.
In this Advanced DAX Tutorial, we cover DAX Aggregation Functions and DAX Rounding Functions with deep practical examples. You will understand how INT, ROUND, ROUNDUP, ROUNDDOWN, MROUND, TRUNC, FIXED, CEILING, and FLOOR work with decimal values like 3.12438 and time values like 9:34:14 AM.
We will break down:
• Rounding down vs rounding toward zero
• Rounding away from zero
• Rounding to a specific number of digits
• Rounding to desired multiple (significance)
• Converting numbers to formatted text
• Handling time rounding using 0:15 intervals
• Choosing the correct function in financial and production models
This is not basic syntax training. This is practical DAX logic designed for real BI developers.
If you are building production-grade Power BI models, this module is essential.
