A variable of type integer can represent a signed four byte integer value. That is, any variables listed as an integer will recognize only whole numbers (ie, 0, 2, -47). If a numeric input for such a variable is not entered as a whole number (for example, if 3.999 is entered), then the variable will only accept the value to the left of the decimal (in this case, 3). The number will not be rounded off. On most platforms, integers in the range -2,147,483,648 to 2,147,483,647 can be represented.
