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(7253.86, 0) -> 7254 ROUND(7253.86, 1) -> 7253.9 ROUND(7253.86,-3) -> 7000
In this example we calculate the population in millions to one decimial place.
SELECTname, ROUND(population/1000000,1) FROMbbc
