C语言求助：Dev上可过，洛谷#3WA

代码如下

#include <stdio.h> 

int main(void)
{
    float number;
    int afterDot, intNumber, digit;

    scanf("%f", &number);

    afterDot = ( number - (int)number ) * 10;
    printf("%d.", afterDot);

    intNumber = (int)number;
    while ( intNumber != 0 ) {
        digit = intNumber % 10;
        printf("%d", digit);
        intNumber /= 10;
    }

    return 0;
}
