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。
Look, part of the reason I'm flaming at you is, something like square root, it seems dumb to write specs on it. Everybody knows what this is going to do. But you want to get into that discipline of good hygiene, good style.

OK, once it gets to the end of that, what's it going to do? It's going to come down here and, oh. What's that doing? Well I cheated when I started. I said, somebody's giving me a perfect square, I'm looking for the square root of it. But suppose 15 I gave this thing 15, and asked it to run.
好,一旦到了循环的最后,程序会去做什么?程序会跳到这里来,噢,这是干什么的?好吧,当我开始的时候我有点小作弊的意思,我说过,我得到了一个完美的平方数,我要求这个数的平方根,但是假设下我得到的数是。
I'm checking that I didn't leave my program because I didn't find an answer. Well this is a good thing, it's better than my program running forever, but it's a bad thing because I don't have it the square root of 0.25.
