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 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
Correct me if i am wrong, please 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. 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). Regarding use for casting, you still see the need for it in some libraries 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).
