Types that store real number values, whose range and precision is determined by the size of the data type.
Data Type Modifiers
Specifies additional characteristics of a standard or user-defined data type.
String types
Types that store or point to an array of characters.
Class types
Types that provide special capabilities to be used directly or to be extended by user-defined types
