To me, it's a way of simplifying a number.
For example, I go on a car journey of 32.561km. When talking to my old Mum, I might say I went for a car trip for about 30km. In other words I rounded to the nearest 10. Later on, talking with my son, I might say, I went on a 33km car trip. It's an approximation that depends on the circumstances (certainly in practical terms).
Using money, say something costs $292.45c. I could say it's about $300 (rounded to the nearest $100), or $290 (rounded to the nearest $10) or $292 (rounded to the nearest $1)
It is very useful.
