求函数值的

firewater

#include <stdio.h>
#include <math.h>

void main()
{
        double x , s;
        printf("input number:\n");
        scanf("%1f",&x);
        s = sin(x);
        printf("sin of %1f is %1f\n",x,s);
}


求不到值，input number:
20
sin of -92559604377396321000000000000000000000000000000000000000000000.000
