• What is the minimum value for the data type double?

  ... a more academic question: what is the minimum value of the data type double? I thought 'double', it is the 8-byte IEEE standard and what I remember, it's + - 1.7E + - 308.  The more different number of 0 should be 1.797E - 308.

  This is why I was a little surprised when I looked at the data output of my calculation of CVI, where I found the numbers with exponents of E-319 or E-324 as the smallest value...

  But I'm sure there's an explanation :-)

  Thank you for sharing with me,

  Wolfgang

  The largest number is indeed the order of + 1.7E + 308; There are a smaller number of - 1.7E + 308. Note that this is in fact the most negative number, which is the smallest by some reckoning. For the small beach of the Exhibitor, things get a little more complicated. 1E-308 can be represented with complete accuracy and resolution, but if you're willing to lose a few bits of precision, you can go down even further. For example:

  Double x, y, z:

  x = 1E-300;

  y = 1E7;

  z = x / y;               Give 1.000000000000000E - 307

  y = 1E8;

  z = x / y;               Give 9.999999999999999E - 309

  y = 1E18;

  z = x / y;               Give 9.999987484955998E - 319

  y = 1E23;

  z = x / y;               Give 9.881312916824931E - 324

  So, as you can see, values less than 1E-308 are possible, but they become increasingly more inaccurate and should not be relied upon.

• How to auto-off rounded af:inputText liaison with the data type Double?

  Hello Experts,

  If a component af:inputText is bind with a field whose data type is Double I saw if I enter 12.0 in the text field, and then it changes automatically to 12. Another example: 12,010 turns into 12.01.

  My requirement is to maintain the value that it has been seized. But the validation client side of the field, that ADF provides by default, should be present. I mean that ADF throws the error message if I get 12a.01; as it is not a Double.

  How can I achieve this?

  Any pointer would be vary useful.

  JDeveloper version: 11.1.1.6.0
  

  No, what I mean is that if you keep the zeros on the right, the data type is not a Double.

  Once you save 12.010 and read it again, you will see zero residue. You would see only the zero if you or the other say the number still show for example 3 fraction digits or if you store the value as a string that will store the entry as is and use a regular expression validator to ensure that only valid numbers are entered.

  In the first case ever number has 3 digits of fraction for example 12-> 12.000 and 12.010-> 12.010

  In summary, you will need to decide which way to go. If the data type must be Double, then there is no zero leakage or you must use the minFractionDigits which will always use the zero leak until the number of spezified. If the does not like what you have to store strings.

• Get the Data Type of queue

  I'm working my way through my first vi producer consumer and I have two questions.

  1 I am the queue data x, y samples acceleration waveform type z. The code snippet shows how to set the data type in the queue to get. It is rather ugly and disturbing, even if it seems to work.  Is there a way more elegant and beautiful to set the data type?

  2. the sampling frequency of the accelerometer is 5120 Hz.  The DAQmx Read buffer is 1024 length samples.  Therefore, it takes 200 [ms] to fill the buffer.  I put the metronome 100 [MS] to ensure that the producer is not without samples.  This means that the loop While producer will spend much of its time waiting.  Right?  Given the wait cost anything?

  In ProducerConsumerExample.vi of LabVIEW, the sampling frequency is 10000.  The size of the read buffer is 1000.  And the metronome is set to 100 [ms].  The sampling frequency of the device comes from the hardware device in the cDAQ.  100 [ms] interval comes from the PC.  It will not be a mismatch?  I would like to understand this before I put my metronome to 200 [ms].

  Then, can shed you some light on the behavior of the loop while you mentioned is not a metronome that is is punctuated by DAQmx? I think it would do a lot of rotation.

  It is not spinning as he waits inside the DAQmx Read for samples N must be obtained.  This isn't a request for data.  It takes time to collect these samples.  That length of time depends on your sampling rate and how many samples you request.  So because he is waiting inside the DAQmx Read, there is no need to add an additional wait.  Let the DAQmx Read limit the rate of the loop.

  It's actually like the loop of consumer for the consumer to the producer.  Playback of the queue will limit the rate at which that loop runs.  It should therefore no waiting.

• To change the data type of control/led

  Is it possible to change the underlying data type of the indicator or a control?  I a VI that I want to use that accepts any type of data (essentially data varriant) and display it accordingly.  I have different controls selected to display data of different types in the sense of data vs decimal boolean data vs integer, but certain types of data will be of type uint32 vs int16 vs uint64 etc..  Is it possible to programmatically change the data type, so I need to have all the combinations of indicators?

  The short answer is no. The long answer is that LabVIEW has not 'generic' controls that allow you to display any type of data (apart from the variant of course). There are several ways to address this problem, but all require you as the programmer to manage explicitly each type of data you could possibly meet. Here are some possibilities (in no particular order), please let me know if you would like to help a particular implementation of these.

  1. Force incoming data to variant, use the info option to determine the data type of the original data in a case structure (open G can do this VERY easy), have an indicator on the front panel for each type of data you want and hide those unused
  2. Use a sub-group of experts on the front panel and sub - vi call of to view specific types (that lends itself very well to encapsulate your data in a class and you leave OOP allows to expand into different types of data)
  3. Use a tab with the variant (similar to option 1) control put each kind of data in its own tab, enable only the current
  4. Do a Control-X to accept a Variant option 1 under the hood
  5. Just as a string of format and use a string indicator

  That's all I can think of right now, once again, let me know if you need more information/help on the options.

• Is it possible to get the data type of element of a queue to itself?

  Hello world

  I have a Q which has a cluster as data type of element.

  now when I want to enqueue

  I will use bundle-default-

  and for this I have to have my current data type

  (long cable as (perhaps after where I got the Q).

  My question is,

  If there is a method/property-node/something that allows me to

  the queue of wire inside Refnum and receive the data element type.

  If I can get into the top of bundle-default?

  (I really want to have this cable in all directions)

  is this the reason why I'm asking here

  aid for the Refnum of outgoing queue to get a queue, the method

  indicates the data type of element and so I hope that there could be a solution.

  thx for your time

  and soon

  j

  Get queue status must be output with the type of data (more precisely an array of the data type and an array of clusters if the data is itself a table). If you do not set the items back to entry to T, this should not even cost anything.

  That said, I agree with others that it is better to what actually a typedef.

• Change the Data Type to node e/s on PXI-7841R FPGA

  I would like to change the data type for the node FPGA of e/s on my card FPGA 7841R (simulation). So far, I have raw data (I16). I want to test something with the calibrated data (FXP).

  The cRIO, you usually go to the properties of module to change the calibration mode...

  I searched 7841R documentation and could not do any weather information this calibration mode was also available on this map.

  Any tips?

  Vincent

  The new maps in the series R offer node fixed point IO (for example, the SMU-7858R), but as mentioned all the old PXI based cards R-series offer only modes of measurement I16.

  Page 22 manual R series is about how to do this conversion: http://www.ni.com/pdf/manuals/370489g.pdf#page=22

  Specifically, it notes that you can calculate the voltage by (output Code I16) * 10.0V / (32 768).

  Even if this can use FPGA resources, it records the host do the same conversions. RT old target with slow processors doing the conversion of I16 or FXP to SGL on the FPGA has saved a lot of time CPU

• Modification of the data types of the custom shared variables

  My application includes a library containing a number of shared single process variables. I use type defs to create the shared variable "of the custom control." I know that shared variables do not-automatic update since the type defs, so I'm updating shared variables (data type, do a right click, properties) whenever I update the type definitions.  However, if I make a change to a type design that does not change the data type, for example to change the labels controls, these changes will be reflected in the shared variable.  The data types of variable window shared list contains entries for each previous update, which indicates he uses the previous entries.  How can I make the window of properties of shared variables 'forget' my previous defs type wandering without deleting the variable total? Withdrawal and replacement would be troublesome because the done variable references throughout my project.

  Thank you

  Wes

  The variable is not in the Distributed System Manager, or Manager of the Variable, and cancellation of the deployment has not been resolved.  However, I found Labview from closing completely and reboot clears the memory of the previously used custom data types that sees the library.  Thus, the effective workaround I found is:

  1 make a significant change to the data type of the type (per your suggestion) FED. Record.

  2 - redefine the variable screw-notice type FED.

  3. save the project. Close and restart labview.

  4 - the old def type is now disabled.

  5. return the significant change of the def type, implement trivial change and save.

  6 redefine the variable using the type correct now def. Viola!

  Thank you!

• Hello friends, I want to know what the data type can be declared in pl/sql, but cannot be declared in sql?

  Hello friends, I want to know what the data type can be declared in pl/sql, but cannot be declared in sql?

  Hello friends, I want to know what the data type can be declared in pl/sql, but cannot be declared in sql?

  That question is ambiguous: there is NOT a SINGLE type of data that can be declared in pl/sql, but not in sql.

  The Oracle documentaton is your friend.

  The doc of the SQL language treats the SQL data types.

  http://docs.Oracle.com/CD/B28359_01/server.111/b28318/datatype.htm

  The doc PL/SQL does PL/SQL data types. Because PL/SQL is a language of proceedings (and sql is NOT) there are several types of data, as shown in this doc, PL/SQL-specific:

  PL/SQL scalar data types are:

  • SQL data types
  • BOOLEAN
  • PLS_INTEGER
  • BINARY_INTEGER
  • REFCURSORexplained in "Cursor Variables"
  • User-defined subtypes

  ALWAYS start with the Oracle documentation for these fundamental questions.

  Several times, as with this question, the question is too general to give a simple answer.

• script to change the data type of column

  Hi gurus of the oracle.

  I have 190 tables in my database.

  I have the column type CHAR of all these tables data.

  I need to change the data type of CHAR in VARCHAR2 for all these tables...

  There the script to change the data type of all tables at once?

  Please help me in this regard.

  Thanks in advance

  REDA

  Hello

  There is nothing built-in to Oracle SQL to do.  Maybe your front-end has certain characteristics.

  You can write dynamic SQL statements to do.  In other words, you can write a query that the output is a SQL script like this:

  ALTER TABLE TABLE_A CHANGE (A_TXT1 VARCHAR2 (5))

  A_TXT2 VARCHAR2 (10));

  ALTER TABLE TABLE_B CHANGE (B_TXT1 VARCHAR2 (5));

  with one row for each column of type CHAR.  Notice how the first line of output for each table begins with ALTER TABLE... but the later lines at the same table.  Similarly, the last line of a table (which will be the same as the first row, if the table has only one column of type CHAR) to end with a semicolon, but other lines are not.

  Here's a way to generate and execute such a dynamic script in SQL * more:

  -Disable the features that make the output easy to read, but hinder the execution
  SET FEEDBACK OFF
  SET LINESIZE 500
  SET PAGESIZE 0

  -Create fix_char.sql
  COIL c:\some_pathename\fix_char.sql

  SELECT THE CHECK BOX
  WHEN ROW_NUMBER () OVER (PARTITION BY table_name
  ORDER BY column_name
  )  = 1
  THEN 'ALTER TABLE ' | table-name
  || "CHANGE (").
  ELSE «»
  END
  ||        column_name
  ||        "VARCHAR2 (').
  ||        DATA_LENGTH
  ||        ')'
  ||        CASE
  WHEN ROW_NUMBER () OVER (PARTITION BY table_name
  ORDER BY column_name DESC
  )  = 1
  THEN '); "
  Output END AS
  Of user_tab_columns
  WHERE data_type = "CHAR".
  ORDER BY table_name
  column_name
  ;

  SPOOL OFF

  -Turn on the features that make the output easy to read, but hinder the execution
  SET FEEDBACK ON
  SET LINESIZE 80
  SET PAGESIZE 50

  -Fix_char.sql performance
  @c:\some_pathname\fix_char

  It's good to change all the CHARIOT of VARCHAR2 columns.  The CHAR data type is nothing trouble.

  If iam thinking is possible that we can change the data type of number of varchar2 data type column in a view?

  Or should I follow create or replace type as whenevr the nonnumeric data tries to bring into view
  sound by giving the number plsql for digital character conversion error since it is a number of data type here.

  I have been created as below in the region of production.

  CREATE OR REPLACE TYPE PROD. (OBJECT) ACE FEATURE_CUSTOM_LIST_OBJ

  OK - but it is a SCALAR - not a collection object

  And the view is created below the base have the PROD. FEATURE_CUSTOM_LIST_OBJ

  CREATE OR REPLACE FORCE VIEW PROD. TERMINAL_FEATURE_TYPE

  No - it isn't. Your type of object is a SCALAR - not a collection. You need create a view on a table or a collection that is treated as a table.

  DDL perspective you posted doesn't even mention your FEATURE_CUSTOM_LIST_OBJ.

  If iam thinking is possible that we can change the data type of number of varchar2 data type column in a view?

  Have you tried using TO_CHAR to format the number as a string?

  Using forms 6i how a list item field type DATE data which may contain names of days?

  Set your date as a hidden field (not shown) column. Create your item list with the names of day of varchar2. Create the list item as a base table field that accepts the values of text in the names of the days. On this area, create a when-validate-item trigger that translated the text into an actual date that it then uses to set the value of the real object of the base table.
