c# - Direct casting vs as operator? - Stack Overflow Direct Casting Types don't have to be strictly related It comes in all types of flavors 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 IS-A relationship: Change reference type, otherwise throws exception
Regular cast vs. static_cast vs. 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) dynamic_cast (expression)
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
casting - Explanation of ClassCastException in Java - Stack Overflow Do you understand the concept of casting? Casting is the process of type conversion, which is in Java very common because its a statically typed language Some examples: Cast the String "1" to an int, via Integer parseInt("1") -> no problem Cast the String "abc" to an int -> raises a ClassCastException Or think of a class diagram with Animal class, Dog class and Cat class
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
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
Type-casting in C++ - Stack Overflow Casting one of the operands of to double which will lead to the other getting implicitly converted to a double too, and thus the division (and its result) would now be floating-point Had you been doing just double x = a;, you can do away with the explicit conversion since an int is implicitly converted to a double (live example)
Casting variables in Java - Stack Overflow Regarding use for casting, you still see the need for it in some libraries Pre Java-5 it was used heavily in collections and various other classes, since all collections worked on adding objects and then casting the result that you got back out the collection
How can I convert a string to an integer in JavaScript? In absence of OP's clarification, this question could be interpreted in the sense of converting any string to a number, i e turning "dog" into a number (which of course can be done)
