Direct casting types don't have to be strictly related 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. 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 Regarding use for casting, you still see the need for it in some libraries Do you understand the concept of casting
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 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.
