An Australian company, Electro Optic Systems, has received a $3.5 million government grant to develop the world's first automated, high-precision, laser tracking technology.

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。
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。
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
Even if tomorrow someone were to hand doctors a magic new technology that would enable to control neurons and synapses with whatever precision they want safely inexpensively.
就算明天有人交给医生一项神奇的新技术,让他能安全,随心所欲地控制神经元和神经突触。
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?
