#include "stdio.h"  
int main()
{

double x;
int i;
i = 1400;
x = i;             /* conversion from int to double */

printf("x = %10.6le i = %d\n",x,i);
x = 14.999;
i = x;             /* conversion from double to int */

printf("x = %10.6le i = %d\n",x,i);

x = 1.0e+60;       /* a LARGE number */
i = x;             /* won't fit - what happens ?? */

printf("x = %10.6le i = %d\n",x,i);

return 0;

} 

Output:

x = 1.400000e+003 i = 1400
x = 1.499900e+001 i = 14
x = 1.000000e+060 i = -2147483648
