The int data type is stored internally as a 32-bit integer and comprises the set of integers from -2,147,483,648 (-231) to 2,147,483,647 (231 - 1), inclusive. Previous versions of ActionScript offered only the Number data type, which was used for both integers and floating point numbers. In ActionScript 3.0, you now have access to low level machine types for 32-bit signed and unsigned integers. If your variable will not use floating point numbers, using the int data type instead of the Number data type should be faster and more efficient.
For integer values outside the range of the minimum and maximum int values, use the Number data type, which can handle values between positive and negative 9,007,199,254,740,992 (53-bit integer values). The default value for variables that are of the data type int is 0.
