实现实数的整数与小数部分的拆分

实现实数的整数与小数部分的拆分

代码如下：

// An highlighted bl`
#include <stdio.h>
#include <stdlib.h> 
using namespace std;
void splitfloat( float x, int *intpart, float *fracpart );
 void splitfloat( float x, int *intpart, float *fracpart )
 {
	*intpart = (int)x;
	*fracpart = x- (*intpart);	
}
int main()
{
    float x, fracpart;
    int intpart;
 
    scanf("%f", &x);
    splitfloat(x, &intpart, &fracpart);
    printf("The integer part is %d\n", intpart);
    printf("The fractional part is %g\n", fracpart);
 
    return 0;
}

最多可以提取6位小数
但是当输入7.1时，得到的就是7和0.9999，而输入8.1就是正常的8和0.1
