Every programming language allows to perform operations on some data; different kinds of informations often need different data types.
At the moment Cows can handle three basic data types: integers, strings and booleans. Beside these, there is a compound data type called 'array' which allows to group more data in a single unit.
Integers are the simplest data type: everybody uses them in everyday life. Examples of integers are 5 or 20524; an example of a negative integer is -20. Cows can handle integers ranging from -2.147.483.647 to 2.147.483.647.
