Integers are used when you need a number with no decimal place or it doesn't make sense to have a decimal. Because integers are whole numbers, there are no integers "between" 1 and 2.
In IntValues, the lowest value it can hold is -231 or -2,147,483,648. The highest value it can hold is 231-1, or 2,147,483,647. For the computer geeks out there, this is a 32-bit (or long) signed integer value.
In Lua scripts, there are no specific integer numbers. The number variables are actually double precision floating point (or just 'double') numbers. For more information about this data type, look at the number data type page.
