And if it goes up 6 percent, well you'll go up 10 percent or more, and if it goes down, don't worry, I'm so smart your stocks won't go down.
如果股市涨了6个百分点,你可以转到10以上的百分点,如果股市跌了,你也不用担心,你选择的人会保证你买的股票不会跌。
Another way of saying it is, anything that uses get float doesn't care what the details are inside or shouldn't, and if I change that definition, I don't have to change anything elsewhere in my code, whereas if I just have the raw code in there, I have to go off and do it.
换种说法就是,任何用到获取,输入这个功能的人不用担心具体的实现细节,如果我改变了这里的实现,我并不需要去改变我的代码,因为我的最底处的源码就在这里,我去改这里就可以了。
