Int type values are integers, also known as whole numbers. This type includes values that are integer by their nature. The following values are integers for example: the number of bars in the symbol window (16000 bars), the number of opened and pending orders (3 orders), the difference in points between the current symbol price and the order open price (15 points). Numbers representing such things can only be integers. For example, the number of attempts to open an order cannot be equal to 1.5, but only to 1, 2, 3 and so on.
