To people suggesting a number like 370022 for a given platform in a given week be rounded to 370000: it wouldn't be correct. If calculations bring to a result of 370022 ± error margin, rounding it to 370000 ± error margin wouldn't be the same. Look at the first message of this thread, it's explained quite clearly: that 370022 value is the midpoint of the probability curve of the extrapolation of sales data collected that week. BTW most probably a rounding to the closest unit already happened, as sales are integer numbers, start values are integers and final values must be too, but intermediate values very often won't and calculations will be made keeping all the available decimals in every intermediate result, and rounding will happen only at the end to limit the growth of rounding error, that would just be added to the error already present in the extrapolation.
I'm puzzled, I thought that some basic rules for rounding and about measurement errors were taught also in high-school physics courses all around the world, not just at university.
