正如你希望的我要试着把他们转化为浮点数,等一等。
-
Last time we checked the type and said if it is a float you're okay. If not, carry on.
并且会告之是否是一个浮点数,如果不是继续循环。
-
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。

I just want to float to the dining hall after-- " so much easier, so much less painful."
我只想下午时飘去餐厅-,更加容易，更少痛苦“

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。
-
I can't rely on the user. I want to make sure I get a float in it, so how do I do that?
我想确保这儿我得到的是一个浮点数,我该怎么做呢？
-
Then I'd be multiplying a float by 5, so that's a float times an int.
然后我们把这个浮点数乘以，那是浮点数乘以整型数。
-
- 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。

-
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。
-
So, a 32 bit of float gives you a bunch of precision.
2比特的浮点型数据精度更大。
-
It means anybody using that little function get float doesn't have to worry about what's inside of it. So for example, I decide I want to change the message I print out, I don't have to change the function, I just pass in a different parameter.
这代表着用这个方法去获得浮点数,的任何人都不用担心具体的实现了,例如，如果我想改变下,显示的信息的话，我不必去改变方法，我传个不同的参数就可以了。
-
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。

As you walk amid the buildings and trees, as you see your friends and classmates, allow these emotions to float through you, freely, lightly.
