There are rules about casting pointers, a number of which are in clause 6.3.2.3 of the c 2011 standard 465 casting is different than conversion Among other things, pointers to objects may be cast to other pointers to objects and, if converted back, will compare equal to the original.

23 str(x) returns a new str object, independent of the original int
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)
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. 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 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. 10 convert has an optional parameter style, and i suggest to use convert instead of cast
It helps to avoid confusion
For example, if you write cast('20130302' as date), what would you get March 2 or february 3 Also, if you want specific format when casting to date to string, you bound to use convert 'casting' with reflection asked 16 years, 1 month ago modified 4 years, 6 months ago viewed 65k times
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
