The decimal string to number Conversion, cutting necessary zeros

• "Decimal string to Number.vi" bug in LabVIEW 2009 SP1

  The "decimal string to Number.vi' seems to be the conversion of the input data in the type int32 internally even when the input tape in vi data is expanded floating point (no points of constraint).  This is causing me grief.  See attached vi

  This bug is still present in LabVIEW 2010?

  Thank you

  There is no bug. You use the wrong function (see Help) If you want a floating point output. Use Fract/Exp string to a number.

• String to number conversion problem

  I have a VI that pulls in data from a device using VISA, and I got it on another computer to work a few weeks back. I had to transfer the VI to a laptop computer to run a few tests, and now I can't make it work. I am unable to put my VI because the laptop on it's is unable to access the network companies, I will do my best to explain it all, I apologize for the inconvenience! My problem is not however with VISA, it's with an exit VISA number conversion chain.

  I have attached a painting drawing of VI to better explain it.

  I use the block series Visa football match in baud rate and all that many good things to the unit and port settings set of device management. Then, a while loop is entered. The loop will run until you press the stop"" button. The next block of visa is the writing block, he asks for a reading of the device. The next block of visa is the first block of reading, he returns playback in the form of "NA-XXX. X' where x are numbers. The next block of visa is the second reading block, this block just echoes back the command sent to the device. Playback of the first visa read block, "NA-XXX. X' is going exponential/fractional chain to digital converter.

  When you perform a run/debug to highlight run, the release of visa reports the correct value, is the value of the device reading - however the string to number converter generates a 0,000, no matter what channel number is. I am at a loss as to what may be wrong because it's the EXACT set up I had to work very well a few weeks ago!

  I'm using Labview 10 on the laptop, the old computer was labview 7. I'm guessing that this is perhaps the rub... I Redid the VI from scratch, although I have not opened the old VI in labview 10.

  Any help would be appreciated. Again, sorry I am unable to attach the VI.

  Would it not have been easier to just post a screenshot? You might also have used the Tool of Capture of Code. (Which reminds me that I need to install it to my previous versions of LabVIEW, as evidenced by the screenshot I took. )

  As to the question: you probably either:

  • employee analysis of chain initially and when you rewrote the VI you used the regular string conversion functions.
  • Wired an offset value in the string to the number function.

  Hello
  
  I have a string, for example '23,2445,45'
  I want to extract the numbers of this string and put it in an array of numbers.
  
  Any keyword SQL is available. What is the best way to do it.
  
  Thank you
  MD

  Try this

  declare
  
  type vnum is varray(20)  of number;
  
  vnum1 vnum :=vnum();
  
  j number;
  
  begin
  
  j:= 1;
     for i in (
     with t as (
     select '23,2445,45' product_string from dual
     )
     SELECT   *
         FROM (SELECT
                      RTRIM(LTRIM(SUBSTR(product_string,
                                         INSTR(',' || product_string||',', ',', 1, n),
                                           INSTR(',' || product_string||',', ',', 1, n + 1)
                                         - INSTR(',' || product_string||',', ',', 1, n))),
                            ' ,') AS prod
                 FROM t,
                      (SELECT     ROWNUM n
                             FROM DUAL
                       CONNECT BY LEVEL < 10))
       WHERE prod IS NOT NULL)
       loop
  
       vnum1.extend;
       vnum1(j):= to_number(i.prod);
  
       dbms_output.put_line(vnum1(j));
  
       j:=j+1;
  
       end loop;
  
       end;
    
  

  vnum1 vnum: = vnum (0,0,0,0,0,0,0,0,0);

  I did it because I don't know how to initialize the array. Need to read more about it.

  This will put the values in the vnum1 table.

  If you need to do something with the numbers in the string

  so you can do the following without using a table.

  declare
  begin
     for i in (
     with t as (
     select '23,2445,45' product_string from dual
     )
     SELECT   *
         FROM (SELECT
                      RTRIM(LTRIM(SUBSTR(product_string,
                                         INSTR(',' || product_string||',', ',', 1, n),
                                           INSTR(',' || product_string||',', ',', 1, n + 1)
                                         - INSTR(',' || product_string||',', ',', 1, n))),
                            ' ,') AS prod
                 FROM t,
                      (SELECT     ROWNUM n
                             FROM DUAL
                       CONNECT BY LEVEL < 10))
       WHERE prod IS NOT NULL)
       loop
  
  -----Do what ever you want with the number.
  
       dbms_output.put_line(i.prod);
  
       end loop;
       end;

• Target using the VAR String and number

  This should be simple, how to target a VAR using a string and a number, the idea is that I can change the number to target this VAR.

  var gogo1:Number = 12

  var gogo2:Number = 89

  trace ("gogo" + 2)

  I'm after the trace to be 89 NOT gogo2

  trace(this["gogo" + 1]);

• Insert the record with the decimal string?

  I want to insert a record with commas, as the below:

• Place the decimal point in a number

  We use the Oracle 10 g on Linux:
  
  I have an obligation to show the decimal point a number based on certain opinions. By example, if I give myself the number = 12345 and decimal_place = 2, then the output should be 123.45. To meet this requirement, I wrote the code which works great but very slow because it is running in insert statement for each row.
  
  code
  

  define value=45896;
  define dec=1;
  select substr(&value,1,length(&value)-&dec) || '.' || substr(&value,length(&value)-&dec+1) x from dual

  output

  4589.6

  I can it adjust more?

  select to_char(&valu / power(10,&deci ),'FM999999D'||rpad('0',&deci,'0'),'nls_numeric_characters = ''. '' ') from dual;

• The hexadecimal string to decimal content content

  I write a code in LabVIEW to convert MBus data for some energy meters.

  Apparently the meter that I use sends the data as a string in hexadecimal format, however after correctly parking that string in hexadecimal format, the real value is the decimal number in this hexadecimal string without conversion.

  Example:

  -Response of the meter (String in hexadecimal display):

  68 37 37 68 08 07 72 89 12 13 67 A7 32 04 04 00 00 00 00 0C 06 09 58 02 00 0C 14 39 13 79 00 0B 2D 47 00 00 0 B 3 B A 30 32 00 5-0 HAS 81 03 0A 5TH 68 0 A 03 62 13 00 0F 21 04 00 00 20 86 16

  -After parking, I get 22 bytes to 25 (09 58 02 00) in the right order, i.e. 09 58 00 02 meaning 25 809 MWh.

  This means that I need to transfer sort the string in hexadecimal numbers to display a decimal format and divede by 1000 to get the correct value in MWh.

  I tried to use the Type Cast and Conversion of string without success. Can someone please help me find a solution?

  Best regards.

  How's this for simplified?

  

• Cut the decimal value in the input text

  Hi all

  JDeveloper version: iam using jdev version 11.1.1.6.2

  I need to cut the decimal when the user enters a decimal value.

  IAM a table with one column as editable.

  For example:-If the user enter 123,53 in the editable column, tab press ENTER key press or move to the next row, I want this value to be changed like 123.

  Guide me on how to do this. I tried with VO/OT Format, convert number, nothing helps me.

  Reg,

  Lakshmi.

  USE IT FOR YOUR NEED...

  that assumes that you have a table in which a column is ok SALARY, then add a ValueChangeListener on data from this column and AutoSubmit = true and also immediate = true and then write the code in valueChangeEvent as below...

  public void decimals (ValueChangeEvent valueChangeEvent)

  {

  RichInputText sal = (RichInputText) valueChangeEvent.getComponent ();

  s oracle.jbo.domain.Number = (oracle.jbo.domain.Number) valueChangeEvent.getNewValue (); for Type conversion

  int a = s.intValue ();

  sal.setValue (new oracle.jbo.domain.Number (his));

  RequestContext adfContext = RequestContext.getCurrentInstance ();

  adfContext.addPartialTarget (sal);

  }

  DO it this way, I hope that the problem will be solved.

• Is the locale-specific number conversion chain?

  I would like to know what effect the computer's regional settings may have on the string number conversion in AS3. Specifically, in locales that use a comma as the decimal separator instead of a period, different conversion methods (Number() function, parseNumber(), Builder of the Number() class) they treat the comma as decimal separator? None of the documents I've read resolves this problem and all the examples use periods as a decimal separator. I suspect periods in strings will always be handled as decimal separators (and this is the behavior I want), but I would like to know for sure.

  FTR, an Adobe employee comes to informs me on programmers list that the answer to this question is no. period is always interpreted as a decimal separator, regardless of the location of the BONE.

• Varchar2 to the number conversion problem

  I have some difficulty conversion strings to numbers. On my Oracle 9.2 server, it gives me an error ORA-1722:
  SELECT TO_NUMBER ('1.2') OF DOUBLE
  Apparently, this is because my server is configured to use the Greek number format (comma instead of decimal point) and substitute "1.2' above with '1.2' will work correctly."
  Is it possible for me to convert strings with decimal number type, independent of the culture so that my application will not have to depends on the locale setting of the server?
  
  Thank you.

  Hello

  Welcome to the forum!

  If you don't want to change the NLS settings for your session, you can specify what settings to use for a particular call to TO_NUMBER (and other features), like this:

  ALTER SESSION     SET NLS_TERRITORY = GREECE;
  
  SELECT     TO_NUMBER ('1.2')     AS wont_work
  FROM     dual;
  
  SELECT     TO_NUMBER ( '1.2'
              , '999999999.999999'
              , 'NLS_NUMERIC_CHARACTERS = '',.'''
              )          AS n
  FROM     dual;
  

  The output below shows the TO_NUMBER 1-argument fails, but the 3-argument TO_NUMBER works:

  Session altered.
  
  SELECT  TO_NUMBER ('1.2')       AS wont_work
                     *
  ERROR at line 1:
  ORA-01722: invalid number
  
           N
  ----------
         1,2
  

  The actual format of the string (the first argument) should not match precisely the format mask (the second argument). You can include signs, or omit the decimal points, so '3', ' '-1,2. '-3', ' + 1.2 ' and ' + 3' will be all converted correctly.»»» "

• Sub - VI with the entry as a string og number

  At this small Subvi. I wonder if I could make it more flexible and be able to take the string and number as a value ('value dbl' market) entry.  Is there some sort of variable of variant type that could be used?

  It is possible with the key to write OpenG (varying) _ogtk.vi. But the problem is that when you want to read this back, you need to know what type it is. If you write to a different section of the config file each with a specific type, the TI will work. With this solution, you must use the key to reading OpenG (varying) _ogtk.vi to read and convert the value to LV

  Another way is to use Get Type Information.vi of the Variant Data Type palette. The trick here is to convert double or string before saving it in the config file (wire structure dealing with the output type of the vi and do conversions in the case of type dbl and string). Here, too, you must use a different section, one for dbl for string. Here, you use the standard Read button live file configutaion palette.

  Hello OzShimon,

  It's weird, I just tried your code and get this result:

  

  I noticed that this behavior can be changed in the configuration "Regions and languages" of Windows. In Windows 7, it's this dialog box:

  

  If I change the settings of this dialog to any of the zeros, the result is the same as you have described.

  Can you check your Windows settings and confirm that yours looks the same as mine?

• How do to convert the string (with the Hex data) in number?

  Hello

  I use TestStand 3.5 to automate a few test cases associated with boot loader.

  The requirement is that I need to read the value in some places for specific address. The values of these addresses are stored in a hexadecimal format.

  We have a step customized in TestStand through which we can read these values by address, but she returns as the type "String".

  For example, the value to 0 x 0000008 is 000001 B 2, and he returned in Locals.Value_Read as "000001 B 2" in the string.

  Is it possible, I can convert the string "000001 B 2" to a number?

  I tried to use the function-> val (locals. Value_Read), but it is return 0 as TestStand figures that the input string is not representing the valid number.

  Please help me with this.

  Thank you and best regards,

  Niraj.

  Try: Val ("0 x" + Locals.Value_Read)
