用C语言按特定公式求π值，误差小于10的 -7 次方！

```c #include <stdio.h> int main() { double pi = 0.0; double sign = 1.0; double denominator = 1.0; double term; while (1) { term = sign / denominator; pi += term; if (term < 1e-7) { break; } sign = -sign; denominator += 2; } pi *= 4; printf("pi = %.10f\n", pi); return 0; } ``` ######[AI写代码神器 | 137点数解答 | 2024-10-16 14:55:16]
