Casting Machine

Understanding casting machine requires examining multiple perspectives and considerations. c# - Direct casting vs 'as' operator? Direct Casting Types don't have to be strictly related. It comes in all types of flavors. Equally important, custom implicit/explicit casting: Usually a new object is created. Value Type Implicit: Copy without losing information.

Value Type Explicit: Copy and information might be lost. Moreover, iS-A relationship: Change reference type, otherwise throws exception. c++ - When should static_cast, dynamic_cast, const_cast, and ....

The C-style casts can do virtually all types of casting from normally safe casts done by static_cast<> () and dynamic_cast<> () to potentially dangerous casts like const_cast<> (), where const modifier can be removed so the const variables can be modified and reinterpret_cast<> () that can even reinterpret integer values to pointers. dynamic_cast - Stack Overflow. Static cast is also used to cast pointers to related types, for example casting void* to the appropriate type.

dynamic_cast Dynamic cast is used to convert pointers and references at run-time, generally for the purpose of casting a pointer or reference up or down an inheritance chain (inheritance hierarchy). Another key aspect involves, dynamic_cast (expression) Casting variables in Java - Stack Overflow.

Casting in Java isn't magic, it's you telling the compiler that an Object of type A is actually of more specific type B, and thus gaining access to all the methods on B that you wouldn't have had otherwise. It's important to note that, you're not performing any kind of magic or conversion when performing casting, you're essentially telling the compiler "trust me, I know what I'm doing and I can guarantee you that this ... Another key aspect involves, casting - Converting double to integer in Java - Stack Overflow. is there a possibility that casting a double created via Math.round() will still result in a truncated down number No, round() will always round your double to the correct value, and then, it will be cast to an long which will truncate any decimal places. Equally important, safe casting in python - Stack Overflow. Casting has sense only for a variable (= chunk of memory whose content can change) There are no variables whose content can change, in Python.

There are only objects, that aren't contained in something: they have per se existence. Then, the type of an object can't change, AFAIK. Then, casting has no sense in Python.

That's my believing and opinion. Correct me if I am wrong, please. casting - How to cast int to enum in C++? How do I cast an int to an enum in C++? For example: enum Test { A, B }; int a = 1; How do I convert a to type Test::A?
