It comes in all types of flavors Usually a new object is created Copy and information might be lost Change reference type, otherwise throws exception. Static cast is also used to cast pointers to related types, for example casting void* to the appropriate type 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 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. 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
That's my believing and opinion Correct me if i am wrong, please Regarding use for casting, you still see the need for it in some libraries Vb actually has 2 notions of casting Clr style casting lexical casting clr style casting is what a c# user is more familiar with This uses the clr type system and conversions in order to perform the cast
Vb has directcast and trycast equivalent to the c# cast and as operator respectively Lexical casts in vb do extra work in addition to the clr type system 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). The real question is what you want to do when/if the value in the unsigned int it out of the range that can be represented by a signed int If it's in range, just assign it and you're done
