一些数学函数

fmod

#include <stdio.h>
#include<math.h>
int main(int argc, char *argv[])
{
    float a,b,c;
    while (scanf("%f %f",&a,&b))
    {
        c=fmod(a,b);
        printf("%f
",c);
    }
    return 0;
}

{
    float a,b,c;
    while (scanf("%f %f",&a,&b))
    {
        c=fmod(a,b);
        printf("%f ",c);
    }
    return 0;
}

floor 向下取整

#include <stdio.h>
#include<math.h>
int main(int argc, char *argv[])
{
    float a,b,c;
    while (scanf("%f",&a))
    {
        c=floor(a);
        printf("%f
",c);
    }
    return 0;
}

        c=floor(a);
        printf("%f ",c);
    }
    return 0;
}

ceil 向上取整

#include <stdio.h>
#include<math.h>
int main(int argc, char *argv[])
{
    float a,b,c;
    while (scanf("%f",&a))
    {
        c=ceil(a);
        printf("%f
",c);
    }
    return 0;

        c=ceil(a);
        printf("%f ",c);
    }
    return 0;
}

sin正弦函数

#include <stdio.h>
#include<math.h>
#define PI 3.1415926
int main(int argc, char *argv[])
{
    float a,c;
    while (scanf("%f",&a))
    {
        c=sin(a/180*PI);
        printf("%f
",c);
    }
    return 0;
}

四舍五入

#include <stdio.h>
#include<math.h>
int main(int argc, char *argv[])
{
    float a,b,c;
    while (scanf("%f",&a))
    {
        c=floor(a+0.5);
        printf("%f
",c);
    }
    return 0;
}
