代码如下，不知道怎么把小数点放进去，求大神帮助！
#include <stdio.h>
int a=10000,b,c=35000,d,e,f[35001],g;
main() {
int i;
for(i=0;i<c;i++)
     f[i]=a/5;
while(c!=0)
     {
         d=0;
         g=c*2;
         b=c;
         while(1)
            {
                d=d+f[b]*a;
                g--;
                f[b]=d%g;
                d=d/g;
                g--;
                b--;
                if(b==0) break;
                d=d*b;
            }
         c=c-14;
         printf("%.4d",e+d/a);
         e=d%a;
    }
}
