用 C 语言按公式求 π 值，误差小于 10 的 -7 次方！附代码实现

```c #include <stdio.h> int main() { double pi = 0.0; double sign = 1.0; int denominator = 1; double error = 1.0; while (error >= 1e-10) { pi += sign / denominator; sign = -sign; denominator += 2; error = sign / denominator; } pi *= 4; printf("pi = %.10f\n", pi); return 0; } ``` ######[AI写代码神器 | 129点数解答 | 2024-10-16 14:52:28]
