double xpow( double radix, double exp )
{
double result = 1;

while( exp-- )

result*= radix;
}

return result;
}

void main()
{

int res2 = xpow( 3, 3 );
double res = xpow( 2, 2 );

printf( " %d \n ", res2 );
printf( " %d \n ", res );
}

man 3 printf

printf( " %f \n ", res );

res isn't int... it's double
