SELECT IF((col1+col2) = FLOOR(col1+col2),FLOOR(col1+col2), col1+col2)

SELECT IF((1+1.1) = FLOOR(1+1.1),FLOOR(1+1.1),1+1.1) Results 2.1
SELECT IF((1+1.0) = FLOOR(1+1.0),FLOOR(1+1.0),1+1.0) Results 2

Since everyone keeps bringing up Innodb's shared tablespace, I will point
out that Innodb has a file-per-table option where each table has it own
