Sum of two floats with 2 decimal places resulting in 4 decimal places in JAVA

I am having a problem in JAVA where I want to store calculation results with only 2 decimal places in SQL Server. For this at the end of my calculations I perform:

Math.round(valor * 100.0f) / 100.0f;

To get the value with two decimal places. After entering the values in the bank I am querying them and really are only stored with 2 decimal places.

When I perform the request for SELECT they are coming with 2 decimal places as well.

But the strange happens when I try add two of these values, the result of this sum gives a number with 4 decimal places, follows debug image:

What could be happening? Is this way of rounding right?

Also when requesting INSERT (just to make sure that the value will be inserted with 2 decimal places):

INSERT INTO tableX (valor) values (ROUND(?,2))

But continues to result in a number of 4 decimal places after the sum.
