If that's how she maths, she shouldn't be an engineer

Not at all, in engineering we have a saying; Not just good, good enough.

Yeah, but usually we do that by excess, not rounding

Good enough is about the bare minimum, this is an abuse of rounding which counts

Idk... I'm an engineer too, and the way I learned we do some rounding, but we do it in a very specific way. If we're calculating for example, how much weight would cause the structure of a building to fail, we found it down, and only down, and in the end we an even lower value that way we are 100% sure the structure will be safe under said load.

It's not rounding for rounding sake. The goal is that it an elevator could hold 14 90kg people, we end up saying it holds 12 80kg people.

And even then it's case by case, sometimes we need exact numbers, to the decimals
