Rounding means adjusting numbers to a specified decimal place or nearest whole number.
In my project, revenue values like 1234.567 were rounded to 1234.57 for reporting.
It makes dashboards easier to read and avoids clutter in visuals.
Scaling means converting numbers to a different unit or range.
For example, sales in rupees were scaled to lakhs for summary charts.
We also normalized percentages to 0–100 range for comparison.
