Rounding result of expression in SELECT ..AS..

I have three columns in my table:
netcost integer(9,2)
taxsum integer(9,2)
quantity integer

In my SELECT I have:

SELECT (netcost+taxsum)*quantity AS totalcost FROM etc etc

My problem is that the value in totalcost is, like, 49.500000000000

SELECT round((netcost+taxsum)*quantity, 2) AS totalcost FROM etc etc

gives the same result.   What I want is 2DP, ie 49.50 in this example.  Is there a way to achieve this?

TIA and for past help.
