另外，计算平方根。

Otherwise, calculate the square root.

我可以检验它，因此如果这是其它计算的一部分我想知道，它能否找到一个完全平方根呢？

I can check it, so if this was part of some other computation, I want to know, did it find a perfect square or not?

假设我想在一大段代码中，计算很多次平方根。

Suppose I want to compute square roots a lot of places in a big chunk of code.

What is that? It's the piece of code we wrote for computing square roots, square roots of actually perfect squares.

对吧？这是什么呢？,这是我们写的计算平方根的代码，计算完全全平方根的。

All right, this is actually a very old piece of imperative knowledge for computing square roots, it's attributed to Heron of Alexandria, although I believe that the Babylonians are suspected of knowing it beforehand.

好，这是一个很古老的,关于计算平方根的程序性知识，是亚历山大的海伦提出的，不过我怀疑在那之前,巴比伦人就已经猜想过了。
