编程实现：利用公式计算n=1000时π的值

解：由题意，函数pi(n)的功能是利用公式计算$\pi$ 的值， 所以函数pi(n)的程序代码为： Function pi(n As Integer) As Double Dim i As Integer, ch As Double, sh As Double sh = 0: ch = 1 For i = 1 To n sh = sh + (-1) ^ (i + 1) * (2 * i - 1) * (2 * i - 1) / (2 * i * (2 * i + 1)) ch = ch + (-1)$^$(i + 1) * (2 * i - 1) / (2 * i) Next i pi = sh / ch End Function 在主程序中调用该函数，输出n=1000时的结果是： Sub main() Dim n As Integer, p As Double n = 1000 p = pi(n) Print "当n="; n; "时，$\pi$ ="; p End Sub ######[AI写代码神器 | 251点数解答 | 2024-06-24 00:08:16]
