Why does SQL Server round off results of dividing two integers?

Question

I have a table with a smallint column that contains percentages as whole numbers (i.e., 50, 75, 85, etc.)

When I divide this column by 100, as in

SEL         


        

Answer 1

When you do integer division (integer divided by integer) you always get an integer answer. 50/100 = .50, which is 0 in integer-speak.

Have you tried dividing MY_COLUMN by 100.0?
