這是我的代碼，但它的輸出確實(shí)有意義。long currentTime;long stateStartTime;int delta;float speed;// I do somethingSystem.out.println();System.out.println(currentTime);System.out.println(stateStartTime);System.out.println(delta);System.out.println(speed);System.out.println(delta * speed);System.out.println(currentTime - (stateStartTime + (delta * speed)));stateStartTime += delta * speed;System.out.println(currentTime - stateStartTime);輸出：1350065634345877135006512165683215.0E85.0E80.0-24181867我期待最后兩行是：1268904512689045但令人驚訝的是我得到了上述結(jié)果。為什么？
