用C语言按特定公式求π值，误差小于10⁻⁷！

```c #include <stdio.h> int main() { double pi = 0.0; double sign = 1.0; double denominator = 1.0; double error = 1e-7; double term; while ((term = sign / denominator) >= error) { pi += term; sign = -sign; denominator += 2.0; } pi *= 4.0; printf("pi = %.10f\n", pi); return 0; } ``` ######[AI写代码神器 | 131点数解答 | 2024-10-16 14:44:55]
