Thread: Is double number even or no

Hi
I have to write programm to check if double number is even or no
Number can be negative positive, double or int.
Double number is uneven 0 is even.

Code:

bool is_even(double n)
{
  int number=n/2;
  if(number*2==n)
    return true;
  return false;
}

I have passed all test except one and I don't know where is mistake can you help me.
