It's only an example of casting in a very loose sense (and one i don't think is useful, at least in the context of python code) If it's in range, just assign it and you're done Cast(str, x) simply returns x, but tells a type checker to pretend that the return value has type str, no matter what type x may actually have.

Casting in java isn't magic, it's you telling the compiler that an object of type a is actually of more specific type b, and thus gaining access to all the methods on b that you wouldn't have had otherwise
You're not performing any kind of magic or conversion when performing casting, you're essentially telling the compiler trust me, i know what i'm doing and i can guarantee you that this.
Static cast is also used to cast pointers to related types, for example casting void* to the appropriate type 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). There are rules about casting pointers, a number of which are in clause 6.3.2.3 of the c 2011 standard Among other things, pointers to objects may be cast to other pointers to objects and, if converted back, will compare equal to the original.
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
6 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 How do i cast an int to an enum in c++ Enum test { a, b }
How do i convert a to type test::a? 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
