I have the following issue.
After I extracted two values from the database, I performed a subtraction obtaining a precision issue.
For example, the two values extracted are:
Double a1 = rs.getDouble("A"); ---> 20.4
Double a2 = rs.getDouble("B"); ---> 15.4
and the subtraction returns
Double diff = a2 - a1; ---> 4.999999999999998
My expected result was 5.0 obviously. How can I fix it?
Thanks
