But because you only have a finite number of bits, the takeaway for today is that there's only so much precision.
因为只有有限个比特,今天的重点就是,它就这么点精度。
That kind of problem tends to arise because they're using a language or a computer that only has finite precision and so there are rounding errors.
这类问题已经日趋严重了,由于他们使用的语言或电脑,都是精度有限的,因此存在这样的问题。
You make an observation doing an experiment that is as accurate as you can do.
得到了你能都,做到的最高精度。
So this now is and up here is and let's put in numbers of quarters, so this will be, what will it be?
这一点是上面这点是,接下来我们把精度提高到1/4
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。
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?
