XSLT Bitwise Logic

Question

I have an existing data set that utilizes an integer to store multiple values; the legacy front end did a simple bitwise check (e.g. in C#: iValues & 16 == 16) to see if

Answer 1

XSLT is Turing-complete, see for example here or here, hence it can be done. But I have used XSLT only one or two times and can give no solution.

UPDATE

I just read a tutorial again and found a solution using the following fact. bitset(x, n) returns true, if the n-th bit of x is set, false otherwise.

bitset(x, n) := floor(x / 2^n) mod 2 == 1

The following XSLT

  
    
      
        
            

          

            
Number
            
Bit 3
            
Bit 2
            
Bit 1
            
Bit 0
          
          

              

                
              
              

                
                  1
                  0
                
              
              

                
                  1
                  0
                
              
              

                
                  1
                  0
                
              
              

                
                  1
                  0

into a HTML document with a table showing the bits of the numbers.

Number | Bit 3 | Bit 2 | Bit 1 | Bit 0 
---------------------------------------
   0   |   0   |   0   |   0   |   0 
   1   |   0   |   0   |   0   |   1 
   2   |   0   |   0   |   1   |   0 
   3   |   0   |   0   |   1   |   1 
   4   |   0   |   1   |   0   |   0 
   5   |   0   |   1   |   0   |   1 
   6   |   0   |   1   |   1   |   0 
   7   |   0   |   1   |   1   |   1 
   8   |   1   |   0   |   0   |   0 
   9   |   1   |   0   |   0   |   1 
  10   |   1   |   0   |   1   |   0 
  11   |   1   |   0   |   1   |   1 
  12   |   1   |   1   |   0   |   0 
  13   |   1   |   1   |   0   |   1 
  14   |   1   |   1   |   1   |   0 
  15   |   1   |   1   |   1   |   1 

This is neither elegant nor nice in any way and there are probably much simpler solution, but it works. And given that it is my first contact with XSLT, I am quite satisfied.
