The precision of that,of course, is not to be taken seriously, but it gives you a general idea of when we are talking about.

当然,这个时间的精确度,并没有经过严格考证,但是它使我们对这件事的时间有个大体的概念

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。
