    private bool IsDoubleNotAnInt(double num)
    {
        if ((num % 1) == 0)
        {
            return false;
        }
        else
        {
            return true;
        }
    }

You could check 

n % 1 == 0

to determine this.

You could compare it with value without fractional part:

Math.Floor(n) != n

Use Math.Floor

 if (Math.Floor(number) == number) {
     // yay, an "int"
 }
