And,he and the woman are back to square one.
VOA: special.2009.07.19
Well, I'm going to get back, let's just draw a bigger square than usual that's roughly four times the size.
嗯,返回的是,我画一个更大的方形,大致上是4倍的大小。
Well I'm relying on the contract, if you like, that the manufacturer of square root put together, which is, if I know I'm giving it two floats, which I do because I make sure they're floats, the contract, if you like, of square root says I'll give you back a float.
好吧我能靠一些类似合约来保证,如果这么说你喜欢的话,其实就是当求平方根的方法,获得了两个我已经确认了是浮点数的数后,这个类似合约的东西就会保证,返回一个浮点数。
It's as if we're back to square one with the deep, right?
这就像一切都回到了原点?
I'm given an integer that's a perfect square, and I want to write a little piece of code that's going to find the square root of it. All right so I'm cheating a little, I know it's a perfect square, somebody's given it to me, we'll come back in a second to generalizing it, so what would the steps be that I'd use to walk through it?
完美平方数的整数,我想写一段代码来求这个数的平方根,好,我这儿有点儿作弊了,我知道这是一个完美的平方数了,他们给我的,我们后面会讲怎么产生这个数的,那么我想解决这个问题,需要什么步骤呢?
And if I were to use that again, I'd just put it on your handout, I could go back and rewrite that thing that I had previously for finding the square roots of the perfect squares, just using the FOR loop. OK. What I want to do, though, is go on to-- or, sorry, go back to - my divisor example.
它可以是任意的集合,如果我又要去用这个方法的话,我会把它放在你们的课堂手册上的,我可以回过头去用FOR循环,重新写我们那个求平方数的程序,我想要做的是,是继续-哦抱歉,回到-我的除数那个例子。
