- casting - Converting double to integer in Java - Stack Overflow
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 But after rounding, there will not be any fractional parts remaining Here are the docs from Math round(double): Returns the closest long to
- Casting vs using the as keyword in the CLR - Stack Overflow
Casting can be used on any compatible types, it can be overloaded, and it will throw an exception if the operation fails The choice of which to use depends on the circumstances
- c# - Why should casting be avoided? - Stack Overflow
Bad is a relative term Avoiding casting is a best-practice, but sometimes a programmer has gotta do what a programmer has got to do (especially if you writing a java 1 5+ program that uses a library written for 1 4) Perhaps rename the question, "Why should casting be avoided?"
- powershell - Why Use [PSObject] Type Casting - Stack Overflow
Why Use [PSObject] Type Casting Generally, do NOT use [psobject] casts: In most cases, it is at best an unnecessary, virtual no-op and at worst results in unexpected behavior [psobject] is a meant-to-be-invisible helper type used behind the scenes to transparently wrap instances of (other) NET types It is for this reason that a [psobject] instance that wraps an instance of a NET type acts
- Why is casting a const reference directly to a mutable reference . . .
The superficial answer to the question "why?" is that these simply are the rules of as expressions in Rust Quoting from the Nomicon: Casting is not transitive, that is, even if e as U1 as U2 is a valid expression, e as U2 is not necessarily so With the as operator, you can either perform explicit coercions or casts There is neither a cast nor a coercion to go directly from u8 to *mut u8
- c++ - When should static_cast, dynamic_cast, const_cast, and . . .
The C-style casts can do virtually all types of casting from normally safe casts done by static_cast<> () and dynamic_cast<> () to potentially dangerous casts like const_cast<> (), where const modifier can be removed so the const variables can be modified and reinterpret_cast<> () that can even reinterpret integer values to pointers
- java: How can I do dynamic casting of a variable from one type to . . .
2 Your problem is not the lack of "dynamic casting" Casting Integer to Double isn't possible at all You seem to want to give Java an object of one type, a field of a possibly incompatible type, and have it somehow automatically figure out how to convert between the types
- c# - casting with reflection - Stack Overflow
I know this question is old, but also notice that Convert ChangeType can return a different value than plain casting For example, double d = 5 57293; int i = Convert(d, typeof(int)) will return 6
