四舍五入到最接近的百分比

Question

If I have a formula such as

count(s.listing_id) / count(a.listing_id) * 100

and I want to round to the nearest whole percentage,

would ROUND(count(s.listing_id) / count(a.listing_id) * 100),1) work?

as in if the value is .03881 should be 39?

Answer 1

ROUND( count(s.listing_id) / count(a.listing_id) * 100 ) rounds to a whole number.

ref: the manual

Answer 2

Try adding more brackets. Your formula still technically works in the way of PEDMAS, but this will future proof it.

ROUND(((count(s.listing_id) / count(a.listing_id)) * 100)),0)
