用C语言按公式“π/4 = 1 - 1/3 + 1/5 - ...”精确求解π值，附代码实现！

```c #include <stdio.h> int main() { double pi = 0.0; int sign = 1; int denominator = 1; for (int i = 0; i < 1000000; i++) { pi += sign * (1.0 / denominator); sign = -sign; denominator += 2; } pi *= 4; printf("pi = %.10f\n", pi); return 0; } ``` ######[AI写代码神器 | 124点数解答 | 2024-10-16 14:53:04]
