C语言实现：根据精度求π近似值的代码解析

```c #include <stdio.h> double factorial(int n) { double result = 1; for (int i = 1; i <= n; i++) { result *= i; } return result; } int main() { double eps; scanf("%le", &eps); double pi = 1; double term; int i = 1; do { double numerator = 1; for (int j = 1; j <= 2 * i + 1; j += 2) { numerator *= j; } term = numerator / factorial(i); pi += term; i++; } while (term >= eps); pi *= 2; printf("pi = %.5lf\n", pi); return 0; } ``` ######[AI写代码神器 | 206点数解答 | 2024-11-18 21:29:19]
