How does return actually returns in C?

To fix the issue you can do Neither. DAT_1001b50C >> 0x10 & 0x7fff is (DAT_1001b50C >> 0x10) & 0x7fff. This shifts the value of DAT_1001b50C right 16 bits and performs a bitwise AND with 0x7fff, which keeps the low 15 bits and clears the remaining bits.

Return data from Return.cumulative vs apply.yearly returns differs?

wish help you to fix your issue Discrete returns should be aggregated across time geometrically (multiplicative). Summing discrete returns gives inaccurate results. Return.cumulative uses geometric aggregation by default.
code :
R> Return.cumulative(returns)
                  GOOGL.Adjusted
Cumulative Return     0.04346625
R> apply.yearly(returns+1, prod)-1
           GOOGL.Adjusted
2016-12-30     0.04346625
R> Return.cumulative(returns, geometric = FALSE)
                  GOOGL.Adjusted
Cumulative Return     0.06251856
R> apply.yearly(returns, sum)
           GOOGL.Adjusted
2016-12-30     0.06251856

C# function returns different types. How do I declare return value? Evaluate return value?

will help you The return type of InputBox is object. You can accommodate that with a var, and then match its actual type with the is keyword.
code :
var range = Globals.ThisAddIn.Application.InputBox(Prompt: Prompt, Title: Title, Type: 8);

if (range is Excel.Range)
{
    doSomething(); 
}

How do I make a setf-able a macro that will either return a form that returns a parameter or a form that returns a defau

it fixes the issue There are basically two existing methods that work well in most cases: mutating containers (like hash-tables) or manipulating immutable data (like association lists). What you are trying to do is mutating association lists, which is made a little bit harder to implement correctly and goes counter to the intended usage. It is however still possible to write a macro, as demonstrated below.
Hash tables
code :
(gethash 'priority environment 0)
=> Either the current priority, or zero if no priority is set

(setf (gethash 'priority environment) 10)
=> Replaces priority
(incf (gethash 'priority environment 0))
=> Increment current priority (which defaults to zero)
(defun increase-priority (environment value)
  (acons 'priority 
         (+ (or (cdr (assoc 'priority env)) 0)
            value)
         environment))
 (process value (increase-priority env 1))
(define-setf-expander get-priority (list)
  (let ((current (gensym))
        (new-priority (gensym)))
    (values (list current)
            (list `(assoc 'priority ,list))
            (list new-priority)
            `(prog1 ,new-priority
               (if ,current
                   (setf (cdr ,current) ,new-priority)
                   (setf ,list
                         (list* (cons 'priority ,new-priority)
                                ,list))))
            `(if ,current (cdr ,current) 0)))) 
(let ((list ()))

Function returns null if return is called within a conditional statement despite meeting the condition. Returns expected

Hope this helps Your recursive calls inside bin_sort are missing return before them, so if any recursion at all happens, the top level just returns null.

Yield keyword return 0x107e4b3c0 while Return function only returns Last value in the list

I hope this helps . I created a small program to output Name char along with position of char but it does not work as i expected. , Why not try following...
code :
for n, c in enumerate(name_letters):
    print n, c
name_letters = "Alexi Rodrigo"

n = 0
for c in name_letters:
    if c != ' ':
        print n, c
        n += 1
    else:
        print c
