A more portable option is to use the standard defined style: double SQRT (double d1) throw ;.

一种更加具有可移植性的方法是，使用标准定义的风格：double sqrt (double d1) throw ；。

Now that I've written sqrt, I can just use it anywhere I want in the code. You've got to rely on the fact that I wrote it correctly, but you can basically suppress the details of how it's used.

就是忽略细节,既然我已经编写了sqrt函数,我可以在代码的任何地方使用它，你完全可以依靠,我已经编写的这个函数。

to do sqrt, or square root-- no, I'm going to square root use sqrt, that's the name I'm using here-- square root a hundred different places in some piece of code. Without function, I'd have to copy that piece of code everywhere.

让我做一下准备,想象一下我要调用sqrt或者-,不，我会调用sqrt函数,这是我在这里用的名字，我得把这段代码到处复制。

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。
