C语言 四舍五入(学习转型练习)

#define _CRT_SECURE_NO_WARNINGS
#include<stdio.h>
void main() 
{
    double moeny = 0;
    scanf("%lf",&moeny);
    printf("多少%f元", moeny);
    double rufest = (int)(moeny * 10 + 0.5) / 10.0;
    printf("
rufest=%f", rufest);
    if (moeny<rufest)
    {
        printf("%f元四舍五入",moeny-rufest);
    }
    system("pause");
}

 还是微软牛逼：C#两句话搞定四舍六入：五取偶

  double i = Math.Round(1.25, 1);
            Console.WriteLine(i);
