You may find that
System.out.println( 1.33 - 1.3 );
// output : 0.030000000000000027
The unexpected result is coming from the fact that
internal floating-point number representation is not well suited for that kind of operation.
The easiest way to solve this limitation is to the BigDecimal class :
import java.math.BigDecimal;
...
System.out.println
(BigDecimal.valueOf(1.33).subtract(BigDecimal.valueOf(1.3)));
