大家都知道π=3.1415926……无穷多位, 历史上很多人都在计算这个数, 一直认为是一个非常复杂的问题。现在有了电脑, 这个问题就简单了。
其中有些计算起来很复杂, 我们可以选用图中第三个, 比较简单, 并且收敛的非常快。
因为计算π值, 而这个公式是计算π/2的, 我们把它变形:
π = 2 + 2/3 + 2/3*2/5 + 2/3*2/5*3/7 + ...
-We all know that π = 3.1415926 ... ... infinitely many, many people in history in the calculation of this number has been considered to be a very complicated issue. Now, with computers, this problem is simple. Some of them very complicated calculation, we can choose the third map, is relatively simple and very fast convergence. For calculating the value of π, and the calculation formula is π/2, and we put it deformation: π = 2+ 2/3+ 2/3* 2/5+ 2/3* 2/5* 3/7+ .. .
