So what that means is the compiler is actually going to first "cast" so to speak 13 from whatever it is - to a float -- to a floating point value -- and then perform the division for us.
所以这里的意思是编译器将,做“计算“，譬如13这样一个浮点数,-到另一个浮点数-,然后为我们处理除法。

OK, says it says enter a float. I give it something that can be converted into a float, it says fine. I'm going to go back and run it again though. If I run it again, it says enter a float.
好了，看到他说输入一个浮点数,我输入它可以转换为浮点数的值,那没问题，我回过来再运行一遍,如果我再运行一遍。

它就会抛出一个值错误异常了，它会告诉我输入了一种错误的值。
-
When you think about an int or a float or a dictionary or a list, you knew that there were functions that operated on them.
当你想到整型，浮点型，或者链表时,你知道可以用函数去处理他们,但是当你传递一个参数，例如链表。
-
- And then I divide by an int -- that's okay because so long as you have a float involved at some point early on, you're okay.
然后我除以一个整型数-,那是可以的因为现在为止，我们在之前已经,引入了一个浮点数，你是对的。

I need to have a float. I need to have another float here, it's giving me some information.
这儿还需要一个,它给了我这样的信息。
-
Need to get the base in. Second thing I want to do, I need to get the height, so I'm going to input a value for the height, also as a float, a floating point.
也就是输入底的值，第二件我想要做的，事情就是得到三角形的高,因此我会输入一个值作为三角形的高，同样也是一个浮点数。
-
If I wanted to get full, real division, I should make one of them a float.
如果我想要得到真正的除法答案，我需要把他们之中的一个,变为浮点数类型。
-
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。
-
So if I were to solve this problem, here's the way I would do it. I would say, first thing I want to do, is I want to input a value for the base as a float.
如果我想要解决这个问题，这就是我要解决它的方式了，第一件我要做的事情就是要,输入一个浮点数作为三角形的底。

-
So yes, f is a float, but that solution is too late; we need to fix the problem sooner.
是的，f是一个浮点数，但是那个解决方案太迟了;,我们应该在次之前把问题解决。
-
If we did that, if we moved f minus 32 over to the left, that would give me a floating point answer because f is a float.
如果你那样做，如果我们把，放前面，那将会给我们一个浮点数答案,因为f是浮点数。
-
And again, if I just run this, just to show that it's going to do the right thing, it says enter base, I'm obnoxious, it says oops, wasn't a float, so we'll be nice about it and I enter a height, and it prints out what I expected. I just concatenated those strings together, by the way, at the end.
我再来运行下看是不是做对了,提示输入底，噢，它提示说不是浮点数，我很高兴，然后我输入一个,浮点数作为高度显示结果和我预期的相同,顺便说一句,我只是在最后把这些字符串连接起来了。
-
So it turns out there's a solution to this: If you need more precision, more digits after the decimal point than a float allows, what do you go for instead?
所以这里有一个解决方案：,如果你需要比float类型允许的更高精度，小数点后更多位数,那你该用什么取代它？

> David: At some point in time, I'm going to have to have declared the variable as a float before I can then hand it to printf as the insertion value for that format strength.
>，大卫：在一个特定的时间，我将需要,声明float类型这样的变量,那样我就可以把它打印出来,像是格式化优点的插入值。

I can't rely on Professor Guttag if I give this- if this code to him, I can't rely on him to type in a float. Actually I can, because he's a smart guy, but in general, I can't rely on the user-- I wouldn't do it right to see if you did.
当Guttag使用这段代码的时候-,我不能相信他一定会输入一个浮点数,实际上我能因为他很聪明，但是总体上来讲，别相信用户一定会按照规则来-,我会故意做错来试试你的程序的。
-
So this is something that we would call an integer, or an INT. And this is something we would call a floating point, or a float.
