Stored procedure OUT parameter is rounded

[diamonddragon]

Say there is stored procedure:

PROCEDURE `get_price`(OUT PRICE_X DECIMAL(10.2))

While getting OUT parameter, say:

CallableStatement cstmt = conn.prepareCall("{call get_price(?)}");
cstmt.registerOutParameter(1, 6);
        System.out.println(cstmt.getFloat(1));

result is:

778.0

but field value in database table is :

777.77

Why is that value rounded, when I used sqlType 6 = FLOAT?
How to get exact value as it is in database table field?
