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。

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。

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。

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。

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。

Here I actually need to tell the computer, "Give me some bytes in ram in which to store a value, and that value's going to be a floating point value."

这里我的确需要告诉计算机，“给我一些字节内存,来存储一个值，那个值将是,浮点型的数值“

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。

It's defined in CS50's library; its sole purpose in life is to ask the user for a floating point value and return it.

它被定义在CS50的函数库中，它的唯一目的是,向用户询问一个浮点数的值，然后返回它。
