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。
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。
- 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。
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。
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。
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。
Now, a float is floating point value.
由于,float就是一个浮点数值。
