An array is stored such that the position of each element can be computed from its index tuple by a mathematical formula. Each copy, or instance, of the array formula, performs the same calculation in each cell it inhabits, but each one uses different data. Therefore, each one produces different results. An example of a multiple cell array formula is: {=A1:A2*B1:B2} If the above array formula is in cells C1 and C2 in a worksheet, then the results would be as follows:The array is a basic abstract data type that holds an ordered collection of items accessible by an integer index. These items can be anything from primitive types such as integers to more complex types like instances of classes.
