Classifying numbers with the numeric tower

Показать описание
In this video, I explain what abstract base classes are with the example of the so-called numeric tower. That concept classifies concrete numeric data types (e.g., int's or float's). It is useful to understand the numeric tower as it makes us think in behaviors and hierarchies, a good basis before going into greater detail on object-orientation.

Is it possible to take a view on the whole library of the imported "math"?

You said, that we can classify concrete data types into abstract data types. Are abstract data types, by definition, always a "subset" of concrete data types with specific behavior (similar to the concepts of expressions and statements)?
