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. 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).

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 2 i'm trying to understand how casting between base & derived types exactly works in c++ Static cast is also used to cast pointers to related types, for example casting void* to the appropriate type 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
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 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 If it's out of range, that'll give an unspecified result so you'll probably want to reduce it the right range first, or assign it to a larger signed type.
