operation binary bit


I met a problem with 9 digits in binary bit operation.

Long ago, I handled some binary and remind that the first digit could be considered significant or other meaning see.

Although I suppose the solution as the attachment, I want to know the proper technique in the binary operation.

(1) how can I replace the loop FOR with a simple bit operator?

(2) I am using U16 (16 bit) to adopt all of the nine figures but how to remove the first digit or some numbers in order as a final data? (In my code, I just subtract a number between the calculated number.)

for example, (1) 101000111-> 101000111 or (11)-> 01000111 01000111

(3) in the other curious question, three lower figures (111) is set at my request.

How can I separate or add the figure in calculations for simplicity?

for example, 110100 (high) +(or some operation) (low) 111 = 110100111


Code: LabVIEW 2014.

I use in general AND to hide the bits that I don't care.

It is usually done with some interesting masking (with AND) or the definition of the bits (with the GOLD) and the logical shift.

  • binary bit test


    I need to test every binary bits using the following logical equation.

    How can I do this?

    ((var & (1

    For example

    If var = 0111 and bits = 2 (starting at 0), so third bit of the var is 1 and shift by two

    are equal, this equation will produce TRUE for third bit.

    Thank you.

    The reported scenario looks like this:

    unsigned int a = 1, b = 62;
    unsigned  long long result = 1ULL << a << b;

    The problem arises because of the temporary variable used when do two little is placed in the same line. This separation into two lines will produce correct results:

  • browsers (IE8, Firefox, Google Chrome and Opera) 32-bit and Vista 64-bit


    I have a HP Pavilion dv2842se. I've had a little more than a year. IE 7 was originally installed with a version 32-bit and 64-bit. Not long after that I got it, the 32-bit version stops working. More specifically, as soon as I open the program it would be closed and completely unusable. I couldn't understand the question, so I installed Mozilla Firefox 32 bit and just used that. When the update of IE 8 came out, I downloaded and still had the same problem, so I continued to use Firefox.

    With the help of Mozilla has worked for me until about two weeks ago, when Mozilla started to become more and more reliable and now completely unusable. Assuming that it was a specific problem of Mozilla, I downloaded the 32-bit versions of Chrome and Opera and finished with all versions of four 32-bit navigation programs are the same.

    I realize that I can simply use the 64 bit version of IE8, as I did since I have no choice. However, there is a big problem with this. IE8 does not support Adobe Flash Player, which is required to run virtually all Web sites - including on the main site I use for my college classes. As the main reason that I bought this computer was for College, my computer as a whole is pretty useless to me without a functional browser that supports Adobe Flash Player.

    By the statement of HP, I tried to disable all add-ons, reset all internet settings and uninstall then reinstall Adobe Flash Player. I even on my own I've tried a system restore and scanned for viruses, spyware and software malware. Nothing has worked.

    Please, please, please if there is absolutely everything I can do to restore my browsers 32 bit in a usable state, please help me. I really do not have the money to buy a new computer, and 64-bit operating systems are almost now - standard, so there is no saying that if I bought a new computer for the same thing does not happen everywhere.

    Thanks for any help you can provide! It is much appreciated!

  • How to run a 32 bit 64 bit Windows 7 program. I tried troubleshooting and answered, he ran on older versions of Windows, but that did not help. The program is writing more

    I'm trying to run a writing more on my new computer with Windows 7. It won't work because it is a 32-bit program. I tried troubleshooting and replied he ran in an earlier version of the window, but it will not always be open. Any suggestions?

    ... It won't work because it is a 32-bit program...

    Writing more is an accounting since the beginning of 1990s and support program was interrupted as of January 31, 2006. While I have no personal experience with the program, it is unlikely he was still 32-bit. It is much more likely that it was a 16-bit program, and that's why you have trouble to install and it works on a 64-bit Windows 7 installation.

    If your program or its request for installation is a 16-bit-based program and you have a 64-bit version of Windows it simply does not natively regardless of the compatibility settings. You need to run and install Virtual PC XP Mode to have any chance of a fully operational 16-bit subsystem. If you are running Windows 7 Professional or ultimate, you can use Windows XP Mode and Virtual PC without a second license of Windows.

    Windows Virtual PC

    Note: you can't run XP Mode on Windows Home editions. If you are running Windows 7 Home Premium or somesuch, you use DosBox or any other program 3rd party virtualization that works with Home Premium. Visit the forums dedicated to these programs for more information.

  • Import from 64-bit to 32-bit

    Hi all

    I want to do an exp/imp comes from a basic oracle 64-bit to a database oracle 32-bit. The two are on an OEL (64 5.6 and 5.7 32 bits)
    I was examined in all support Oracle and read the following note:

    How to use the export and import during the transfer of data across platforms or servers on 32-bit and 64-bit [277650.1 ID]

    This, I understand that this is possible, but I don't know how. Can I do the exp with the binary 64 bit and then just import with the binary 32 bits on 32-bit server, or do we I have imp with a 64 binary bits in the 32-bit database?

    Thanks for the tips!

  • Boolean, int, operator precedence and good coding practices

    I am learning Java and just C++. I sometimes met in the same method in the Java application that I learn / maintain within the same if-else blocks in the same method:

    Boolean done;
    State int;
    If (finished & status == 1)
    If (finished & & status == 1)

    They result from the same based on the precedence of the operators.

    Is there a reason to choose one over the other in terms of general practices?

    My preference is that I use the & & when the intention is on each side of the operator, Boolean and & only when I mean bit-wise &. However, if there is another reason to choose the operator of bits in Java can someone let me know?

    Thank you!

    Aksarben wrote:
    If one operand is a Boolean value that is virtually guaranteed to be a mistake.

    If exaclty one of the operands is of Boolean type, it is a mistake, because they do not compile.

    Save yourself the grief and use & unless both operands are an integral part and it is perfectly clear that you intend to a little wise operation.

    Once again: This isn't the issue. In a given context, the single & is a bitwise AND (two numbers of operands) operation, or it's a logical operator AND (the two Boolean operands). With two operands, A and B, it is not possible to do a bitwise operation AND when you wanted to make a logical AND, or vice versa. For any pair of operands, as most of these operations will be semantically meaningful, and therefore the more be syntactically available.

    So, again, use the single & with you want both operands to be assessed, regardless of whether the truth of the expression can be determined by the first single (that is, use it to jump a short circuit), happens when the second operand has a side effect that you always want to happen. And even then, in most cases, you would be better of just evaluation of expressions separately first, store it results into variables and then passing those is & or &, but preferably & because it is more common and less likely to cause confusion. The only real opportunity I could imagine using & is as a shortcut in a State of closure, and even then, it feels bit gross.

    boolean & boolean : logical AND, no short-circuit
    boolean && boolean : logical AND, with short-circuit
    integer & integer : bitwise AND
    integer & boolean : syntax error
    boolean & integer : syntax error
    integer && integer : syntax error
    any_other_type & any_other_type : syntax error
    any_other_type && any_other_type : syntax error
