Rounding problems

I have rounding problems when editing or inserting a new record in float type fields.
e.g. I have a cursor running an agrregate SQL statement. I have a calculated field Sum(DFactor*Cost). DFactor gets values -1,1 and values of Cost in the table have 2 digits. I get these values in a variable e.g. @.FCost. Then I round @.FCost=Round(@.FCost,2).
When I try to inert this value to a new record again I'using Round(@.FCost,2).
However in a lot of records a lot of digits are stored.
I have the same probelm when trying to insert values from MSAccess by ODBC. Although I'm using CLng(@.FCost*100)/100 in order to have 2 digits, a lot of demical values are created.
What is the best practise in order to solve this problem?
Regards,
ManolisIf you are using a FLOAT column to store data of type MONEY, that's a problem. If you are using a FLOAT column to store data of type DECIMAL (x, 2), that's also a problem. Is your underlying problem one of datatype, not actually rounding?
