Question

I am looking for some help.
I am running the following in mySQL

"SELECT AVG(`readingValue`) AS `readingValue` FROM table

This returns the value – 0.0282982

If possible I would like to return only 4 digits rounded up/down to closest.
In this case 0.0283.

Is this possible in the select string, or will I need to do it in php?

p.s readingValue column is float(4,3)

Answer 1

Would the ROUND function be an option?

SELECT ROUND( AVG(`readingValue`), 4 ) AS `readingValue` FROM table
