在任何情况下，计算机科学主要基于近似值，并正在注意可能有一些线条的周围的错误是一个有价值的帮助。
In any case, computer science is mostly based on approximation, and being forewarned that you likely have a bug around some lines is a valuable help.
连续统一体图像作为近似值大部分情况下保持有效。
The continuum picture remains mostly valid as an approximation.
好，我试试求2的平方根，我当然不希望得到一个完全准确的答案了，但是我得到了一个近似值，试试将这个数平方一下，你会发现结果和2相当接近。
All right. I tried it on 2, I surely didn't expect a precise and exact answer to that but I got something, and if you square this, you'll find the answer kept pretty darn close to 2.
