java: How can I do dynamic casting of a variable from one type to . . . 2 Your problem is not the lack of "dynamic casting" Casting Integer to Double isn't possible at all You seem to want to give Java an object of one type, a field of a possibly incompatible type, and have it somehow automatically figure out how to convert between the types
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

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 As

type casting int to double java? - Stack Overflow A variable's type is not only a view (or similar) to the value that you can later widen with some sort of cast It represents the memory space and its value representation inside that space The primitive int type is a 32-bit type that stores integer values in two's complement form After assigning the value to such a variable any further information (about decimals, e g ) are lost

Why when to use `intptr_t` for type-casting in C? intptr_t is a new invention, created after 64-bit and even 128-bit memory addresses were imagined If you ever need to cast a pointer into an integer type, always use intptr_t Doing anything else will cause unnecessary problems for people who need to port your code in the future It took a long time to iron out all of the bugs with this in programs like Mozilla Firefox when people wanted to
