It really depends on context, but if I’m just talking about estimating something, it’s usually rounding a decimal to a whole number or if it’s already a whole number, rounding it to the closest value that is divisible by 5 or 10.
Other than that, it’s basically just about reducing significant figures to make doing rough estimates more easily.
