用 C 语言公式求 π 值，误差小于 10⁻⁷！代码实现揭秘

#include <stdio.h> int main() { double pi = 0.0; int sign = 1; double denominator = 1.0; for(int i = 0; i < 1000000; i++) { pi += sign * (1/denominator); sign *= -1; denominator += 2; } pi *= 4; printf("pi = %.10f\n", pi); return 0; } ######[AI写代码神器 | 210点数解答 | 2024-10-08 22:35:59]
