2. Types and operators
Every program manipulates information, which can take a number of simple forms predefined in a language, or be constructed by composing such simple forms: these are the data types, characterized for the set of possible values, and the operators defined on these values.
2.1 Predefined scalar types
There are 5 in Fortran: integer, real, complex, logic and character. They can all be parameterized with a type parameter (KIND) to define various variants or subtypes:
In each case, there is a preferred subtype, corresponding to the default value of the KIND parameter for that type, and designating the Fortran...
