All right? So if I called sqrt alone, that return test value is done, but in this case I bound it to test, so I can go look at test, and there it is.

执行完返回值语句,但是在这里我将把它赋值给,所以当我看test的值的时候就是返回的值。

And it's just gathering together the multiplications while counting down the exponent. And you can see it when we get down to the end test here, we're going to pop out of there and we're going to return the answer.

这个方法就是通过乘法,来一个一个的减小指数,可以看到,最后面的结果测试，我们会在这里退出,然后返回答案。

If I come into this code, I'm going to check this branch first, if it's not true, ah, there's a return at the end of that branch. If it is true, I do that, and then I've got a second test. If it's true, return I return, otherwise a return.

但是如果我们看看这里,如果我看这段程序,我会先检查这一部分，如果它是假的，啊，这部分分支结尾有一个。

I don't have to go read what it printed out in the screen. This has returned a value that I can use. Because I could do a test to say, is this a return value? If it's not, I'll do something else with it. So the binding is still there, it simply doesn't print it out.

我不想读到屏幕中打印出来的这行字,程序返回过一个我能够使用的值,因为我可以做个小测试，来说明这是否是返回的值，如果不是，我可以做一些其它的事,而这个绑定依然在这儿，没有打印任何东西。

So what's going to happen here? If I'm inside this FOR, OK, and I'm running around, if I ever hit a place where this test is true, I'm going to execute that return, return that return returns from the entire procedure. OK? So the return comes back from the procedure.

那么这里发生了什么呢？,如果我是在这个for循环里面，我正在运行，如果我运行到test的值为真的地方，我就会执行,这个return将会返回整个程序的值,明白了吗？所以它将会从整个程序中返回值。
