ROUND

ROUND(f,p) returns f rounded to p decimal places.

The number of decimal places may be negative, this will round to the nearest 10 (when p is -1) or 100 (when p is -2) or 1000 (when p is -3) etc..

 ROUND(2.7,0) ->  3
 ROUND(2.71,1) ->  2.7

In this example we calculate the population in millions to one demial place.

SELECT name,
       ROUND(population/1000000,1)
