c语言求使用下列公式求π值，要求误差<1010-7。公式为:π/4=1-1/3 + 1/5- 1/7+1/9-.输入格式:无 输出格式: "pi = %.10f\n"输入样例:无输入输出样例: pi=3.1415924536

```c #include <stdio.h> #include <math.h> int main() { double pi = 0.0; double term = 1.0; int i = 0; const double epsilon = 1e-7; while (fabs(term) > epsilon) { pi += term; term = -term * (i + 2) / (i + 3); i += 2; } pi *= 4; printf("pi = %.10f\n", pi); return 0; } ``` [2024-10-01 17:35:36 | 讯飞-星火认知 | 152字解答]
