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> int main() { double pi = 0.0; double sign = 1.0; double denominator = 1.0; double term; while (1) { term = sign / denominator; pi += term; sign = -sign; denominator += 2; if (term < 1e-7) { break; } } pi *= 4; printf("pi = %.10f\n", pi); return 0; } ``` [2024-09-29 11:00:37 | AI写代码神器 | 137点数解答]
