So both of these stories involve floating point values, but only in this case am I actually allocating memory.

所以这两个故事都涉及到浮点类型，但是只有那样我们才能真正地分配到内存。

C So here I'm declaring a variable called c, and I'm pretty much translating the formula from the slide using the characters on my keyboard to a floating point value.

这里我声明了一个变量，然后我把那个幻灯片上的公式,用键盘上的字符翻译成了,浮点数值。

Last thing to say is why would you want to have exceptions? Well, let's go back to that case of inputting a simple little floating point.

最后要讲的是为什么有异常处理？,回到输入一个简单的小浮点数的例子,如果我期望主要是。

It just throws the decimal point away and that's because, again, these are ints and the answer intuitively should be a floating point value, but I need to be more specific.

它直接把小数点后面的数值丢弃掉了，因为，凭直觉，那些整型数和结果应该是一个浮点数据,但是我需要一个更精确的数值。

0 >> David: Yeah, so I very deliberately changed this 9 to a 9.0 so that my math would actually be floating point math involving real numbers and not just integers.

>，大卫：是的，我故意地把9改成9,那样我的数学实际上就是浮点数的了,包括实数，不只是整数。

You can run into issues of things like overflow, underflow, with floating point numbers and when you see a whole bunches of ones, it's particularly a good time to be suspicious.

来看看哪儿会出问题，你可能会碰到浮点数中的溢出和下溢问题,当你碰到一系列这种问题后，可能就会适时的开始怀疑结果的正确性。

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。

There's no decimal point; there's no point zero; there's no floating point value, it's just a hardcoded integer.

这里没有小数点，这里没有;,这里没有浮点数值，它只是一个整型数字。

So a floating point value again is a number with a decimal point, so it depends.

一个浮点型数据就是一个,带小数点的数。

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。

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.

这是我们称之为integer的类型，或者INT，这是我们,称为浮点数的类型，或者浮点。
