• Logical operations on a string of bits

  Hi, I have a very simple question that I can't seem to understand.  I'd just like to perform logical operations (AND, GOLD, etc.) on 2 strings of bits that are 24 bits long each, however I can't find in the palette of functions a function that acts as a binary constant.  I see that constant digital and hex functions.  You can somone please let me know where I can find it.  For example, I would AND ' 111111111111111111111111 '& ' 000000000000000000000000'.

  You know the difference between numeric and string data types in LabVIEW? Blue = digital = integer. Pink = string. In the example you linked to, they use an integer constant when the display format is set to "binary". The 'b' of the constant indicates the radix, which in this case is 'binary '. Right-click on a digital constant and you can change its display format. You can select one of the predefined formats or you can specify a by clicking on the option "Advanced Editing Mode. Eligible formats are defined by using LabVIEW. For example

  %b = binary

  % 8 b = binary, using the width of minimum field of 8, fills spaces (for example, '1101')

  % 08 = binary, using 8 minimum field width, filled with zeros (for example, "00001101")

  example:

  select col1 ,order_by,case when col1 > 10 then 0 else 1 end
  from tab;
  
  select col1 ,order_by,case when col1 <> 10 then 0 else 1 end
  from tab;
  
  select col1 ,order_by,case when col1 not in (10,11,12) then 0 else 1 end
  from tab;
  

  Regarding testing for null, decode the handles which, by default, anyway, so that you can get decode or case easily...

  select col1 ,order_by,decode (col1, null , 0 , 1)
  from tab;
  
  select col1 ,order_by,case when col1 is null then 0 else 1 end

• Boolean logical operation

  Hello! Recently, at work, I was responsible for creating the code that returns something on two Boolean State. Something like: If Boolean has and Boolean B, return if Boolean is and B no Boolean etc something else.

  At first I thought that the best way to do it would be a formula node with the return value is passed through a bunch of if else statements. Then I discovered that Booleans are not supported in notes formulas and forms knots are designed for writing formulas, and not for current programming, that makes sense.

  I came with two ways to do it, but I felt that they were both quite stocky and they suck if I had more than 2 Boolean values my logic on the basis. Here is the code with the two different methods.

  

  I feel like this is an operation that would be much better to do it in an if else statement in code and I would like to know if there is a better way to do this in LabVIEW.

  Typical in LabVIEW is to combine Boolean both in a table, then use of the boolean to number table. This will give you a value between 0 and 3 (included). You can use a single case statement, or you can create a table of values of output desired and use it as an index in the table, or if there is a direct mapping of the enum, you can simply convert that number to the enumeration type.

• Accounts question: logical operator

  Hi all
  
  When I select 'Function' in the menu drop-down menu in the drop-down list box operator on the screen of the logical group of FDM 11.1.3, I get the following error:
  
  The operator must be between 1 and 5 characters.
  
  Why this error is coming?
  
  I use a type of simple logical group.
  I created a simple logic account to map to an account only source in my file to the input source.

• logical AND with the structure of the event

  Hello world

  The structure of the event can manage several events at once to do the same thing: looks like an OR logical operator. But I have not found a way to sequence events to approach a logic and example: you must click on a button to draw, then enter the image would change the mouse cursor. With a structure of the event, I can handle these 2 events separately or together (i.e. change the cursor), but I can't do a sequence of events.

  Is this possible to do with a structure of the event?

  I hope that I am clear (sorry for English btw). And thanks in advance.

  Christophe

  I don't think this is possible directly. You will need to add status information to your event loop that could enforce the order of events and the rules of logic you want. Where transformation you would have to check whether the required event has occurred before this event. If that were the case, perform your treatment. If this isn't the case, ignore the event. Your first event would need set this status information. You can also include some kind of time-out for the second event were to occur within a specific period.

  This type of logic may be better treated with the help of producer/consumer architecture and a state machine in the task of the consumer.

• Application of logic gates on digital data... How does it work?

• How to switch OR logic in DECODE function?

  There is somewhere in my PL/SQL code as embedded in other SQL code. SELECT SUM (DECODE(COL1,'AB',COL2,'AC',COL2,'AD',COL2,'AF',COL2)) FROM DUAL you can see if COL1 is AB, AC, AD, or AF it returns COL2. I was worrying if it takes more execution time. Is there a better way to do this. We can pass the OR logical operator in DECODING so that all objects to check can be passed at any given time? I'm on Oracle 10 g.

  I'd not concerned that such internal function has a performance impact unless you have encountered a specific situation and have evidence to support.

  As others have shown, the other option to DECODE (which is specific Oracle) is to use the CASE (which is ANSI standard), and the CASE is also more flexible in terms of test conditions.

  Performance wise, however, there is little difference between the two.

• Description truncate less/more liquid logic

  I have on my site, two sections: one called a mini description and the other just description.

  I put it in place for the mini description is truncated to 100 characters and show then a button read more to expand and view the description section that shows the description complete.

  Now, I am using a logical operator to the liquid to say:

  "If the characters of description are more than 100, truncated to 100 and then display the Read More button. «But if the characters of description are less than 100, do not truncate and do not show the button read more»

  Now, I have what I think, it is the part of the logic of this sort, but I have a problem with my operators.

  Here's what I put:

  {% If description > '100'-%}

  more than 100 < /p > < p >

  {{description | truncate: "101"}}

  < div class = "horizontal divider" > < a class = 'btn, btn-dark btn - lg btn-contour read_more' > read more < /a > < / div >

  < script >

  $('_{}_.description-short_a.read_more').click (function (event)

  Event.preventDefault ();

  $('.description-short').hide ();

  $('.description').show (700);

  });

  < /script >

  {%-%}

  less than 100 < /p > < p >

  {endif %}

  The problem is, when I use >, it shows the <p > less than 100 < /p > and when I use <, I get more than 100 < /p > < p > MORE, descriptions, even with less than 100 characters, I still get the same result if there were more than 100 characters.

  It is on the top of my head without checking the syntax:

  {% assign desc = description | strip_html-%}

  {% assign DCount = 0-%}

  {% I have in the description-%}

  {% assign DCount = dCount | more: 1-%}

  {% endfor}

  {% If dCount< 100="">

  DO SOMETHING

  {endif %}

• 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!

  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
