In addition to the other answers I think it’s important to note that sometimes it’s necessary to round up or down for real world reasons. If you have a truck that can carry 0.5 Toyota Corollas due to weight, you’re actually going to have a truck that can move 0 Toyota Corollas in most real work applications. You wouldn’t go around advertising that you can move 0.5 Toyota Corollas, you would round down and tell people you cannot move Toyota Corollas.

I remember learning this example from my teacher in second grade.
Imagine that you’re on a journey but the weather is getting bad. You need to travel from mile marker 1 to mile marker 2. At mile 1.4 you decide the weather is too bad, and it’s quicker to go back to market 1 than risk it to mile 2. But what if you made it to 1.5? It’s equally distant to both. You might as well keep going to 2 that’s where you need to go.
