Just a few reminders, if any of you are here for the first time, and I know there are a few, if you go to this particular website, and you can get to this from the classes server as well, you'll see the course website that we've developed and it has a lot more information than if you just go to the classes server and click on the syllabus.
提醒一句,如果有同学是第一次来听课,我看到了有些新面孔,你们可以登录这个网站,从课程服务器也能找到,你们会发现我们更新了课程网站,其中含有大量的信息,若你只访问课程服务器,点击教程大纲

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.

If it's there, I'm done. If not, I go there.
