2's complement of double

Hello,
I need to convert a signed double to a two's complement hex string that is 4 bytes long. How do I go about doing this?
Thanks.

I will try those. But honestly this was the quickest way for me to get it into the format that the hardware will accept. How do I take a negative number and get a two's complement of it?
Thanks
Two's complement is a format. It's a way of storing values. You're not converting anything. Numbers are already stored in two's complement format, so you do not need to do anything.
Perhaps you should read up on two's complement: http://en.wikipedia.org/wiki/Two%27s_complement#Calculating_two.27s_complement

JAVA arithmetic problem with double ?

If I try to work double precision numbers I get a unintelligible result, but what do I do wrong ?
Are there any inaccuracy in the JAVA double precision numbers arithmetic or what's the problem with this very simple example code ? How can I get correct result ?
Simple example code :
================
for (double i = 0; i < 10; i = i + 0.01)
System.out.println(i);

This result is entirely unsurprising, and the flaw lies in your program, not in Java.
Java represents numbers in 2's complement [SEM] form (read the Java Language Specification (JLS), according to agreed standards. When you specify a fractional number that appears to be nice and easy to work with, you are thinking in decimal notation, not binary, and you are giving it a number that cannot be precisely represented. It is a little like asking you to write down exactly what pi is (all its digits ;-)).
So the number you get is not precisely what you asked for (one very insignificant error). But then you compound it by adding an inaccurately represented number to an inaccurately represented number, and so on, until the bit errors combine to make a very inaccurate number.
The correct way to approach what you are trying to do would be to perform the addition using integers, and multiply each time you want to scale it to a double.
This has been asked many times - I would suggest you:
- Search the forums
- Check out the language spec
- or do a degree in CompSci :-)
A calculator is a little more accurate because it does not have to conform to agreed standards, and so can use special logic to minimise such errors. The average pocket calulator also works to a much lower level of accuracy (usu 8 digits), and therefore masks the errors to you. You'd find that you got the same effect if you played with it long enough.
Hope this helps

Howto when i have very very large double array

I have code my program about document retrieval.
I create double array in size [10000]x[8000] for keep value for calculte someting in only memory (about metrix operation).
I have set parameter to heap memory size at 1024m but it not enough, it has exception out of memory.
I use Notebook that have RAM 1G. Is this cause for exception?
Please help me to lead solution for my case.
Thank you.

A couple of points:
1. Your notebook has 1 GB of RAM and you are allocating 1024 MB (=1 GB) to the JVM heap, which is not possible, as you need some space for running various other Operating System processes as well.This is a good point. There are also things in the JVM itself other than the Java object heap that need space. Thread stacks, loaded classes, native libraries, etc.
2. Why have you allocated 1024 MB to the JVM heap? Did you choose any random number (obviously with some degree of educated guess)?
Your array size is 10000 * 8000 = 8 * 10^7
Thus total heap memory required = 8 * 10^7 * 4 Bytes [The int data type is a 32-bit signed two's complement integer]
= 320 * 10^6 Bytes
= 320 MBExcept that peterdog1234 said that the array was an array of doubles, at 8 bytes each, so about 640MB are needed for the array. If the algorithms allow the loss of range and precision, maybe the array could be an array of floats, not doubles. That would keep the array in about 320MB. That would help with the space requirements, but might be slower as all the operations will have to expand the floats to be operated on as doubles, then converted back to floats for storage in the array. But on some architectures that's not too bad.
I would use -XX:+PrintGCDetails to see how the heap has been partitioned into young generation (fast allocation and collection) and old generation (relatively long-lived data). You might have to reshape the heap to have at least 640MB in the old generation, and then whatever you can fit as the young generation, leaving some of your 1GB for the rest of the JVM, other programs running on the box, the operating system, etc. Maybe "-Xms768m -Xmx768m -XX:NewSize=64m -XX:MaxNewSize=64m" would be a good compromise. That gives you a 768MB Java object heap, with 64MB in the young generation and 704MB in the old generation, leaving 256MB (1GB-768MB) for "other things". Whether that works depends on now many other long-lived Java objects you have. But -XX:+PrintGCDetails will tell you that, too.

Use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed the maximum file size (1 MB).

Cuevana extension problem, doesn't appear complements in preferences

Everytime I open Firefox appear a window that says: cuevanatv.asia, I have read blogs where say that I have to delete cuevana extension but in preference doesn't appear the tab of complements.
I also can't open Firefox in safe mode because when I try to open help appears again the tab of cuevanatv.asia.
I already delete Firefox and installed again but that doesn't work.

FA complète + FA épurée

Bonjour,
Je suis en train de développer une interface qui devra être affichée sur deux écrans de PC de la manière suivante :
- un premier écran affichera l'interface complète, à des fins de tests et maintenance ;
- un deuxième écran affichera une interface similaire mais épurée de toutes les commandes et indicateurs qui ne sont pas utiles pour l'utilisation de base de l'IHM.
Par exemple :
- le bouton "Stop Application" se retrouvera sur l'interface complète ET sur l'interface déportée ;
- le bouton "Start Test" se trouvera uniquement sur l'interface complète et ne devra pas être visible dans l'interface déportée.
Ce que je voudrais éviter, c'est dédoubler les commandes et indicateurs (ça ne sert à rien d'avoir 2 boutons "Stop Application") pour ne pas surcharger le diagramme.
J'ai pensé à une solution toute simple : customiser chaque commande qui doit être déportée, en dédoublant l'image du bouton de sorte à ce qu'elle apparaisse 2 fois sur la face-avant, mais 1 fois sur l'écran principal et 1 fois sur l'écran déporté.
J'aimerais savoir si c'est le meilleur moyen de faire cela, ou s'il y a un autre moyen de "déporter" ou "doubler" la FA, sans doubler le diagramme ?
Merci de vos retours,
Cordialement,

Non au contraire Cécile,
Les FGV (functional Global variable) sont selon moi bien meilleur car elles vous permettent de créer un moteur d'action (code dans chaque état) et aussi d'éviter les situations de compétition.
Cependant dans votre cas il suffit de récupérer la référence d'un clone. Etant donné que c'est juste de la lecture, une variable globale suffit amplement.
Pour être sûr que l'on se synchronise sur le terme de FGV voici deux liens:

Reporting Level The Value will Double....

Hi Friends,
IN BI 7.O I Build MultiProvider Based on DSO And CUBE.Here My DSO is Standard and the same DSO Fields are Mapped in to CUBE also.Here My Query Also Standard Query Under DSO,But I copied to Multiprovider.When i execute the Query the Value will be Double.Please let me know the solution for this.
Thanx & Regards,
Raghavendra Bellam.

Hi,
As you are aware that a Multiprovider perform a union operation on data from all the objects underneath it.
If your Query selection fullfil the criteria from the cube as well as DSO the key figure value would be double.
One solution is to provide a variable/Filter for the infoprovider in the query to get result from only one of them.
Hope this solves.

Sales quote layout rows doubled in crystal report layout

Dear All,
Sales quote layout rows doubled in crystal report layout.
In sales quote layout the rows are doubled. Even in the standard layout. If the quote contains only two rows. Then it is doubled as 4 rows in the crystal report layout.
It is happening in the particular database. Other database are working fine. I request you people to help me to overcome this issue.

SSRS Report Returning Double Quote string from a Single Quote String

Hi, I'm getting weird thing in resultset from SSRS report when executed. When I pass parameter to a report, which passes String that has single quote value to a split function , it returns rows with double quote.
For example following string:
'N gage, Wash 'n Curl,Murray's, Don't-B-Bald
Returns:
''N gage, Wash ''n Curl,Murray''s, Don''t-B-Bald
through SSRS report.
Here is the split function Im using in a report.
CREATE Function [dbo].[fnSplit] (
@List varchar(8000),
@Delimiter char(1)
Returns @Temp1 Table (
ItemId int Identity(1, 1) NOT NULL PRIMARY KEY ,
Item varchar(8000) NULL
As
Begin
Declare @item varchar(4000),
@iPos int
Set @Delimiter = ISNULL(@Delimiter, ';' )
Set @List = RTrim(LTrim(@List))
-- check for final delimiter
If Right( @List, 1 ) <> @Delimiter -- append final delimiter
Select @List = @List + @Delimiter -- get position of first element
Select @iPos = Charindex( @Delimiter, @List, 1 )
While @iPos > 0
Begin
-- get item
Select @item = LTrim( RTrim( Substring( @List, 1, @iPos -1 ) ) )
If @@ERROR <> 0 Break -- remove item form list
Select @List = Substring( @List, @iPos + 1, Len(@List) - @iPos + 1 )
If @@ERROR <> 0 Break -- insert item
Insert @Temp1 Values( @item ) If @@ERROR <> 0 Break
-- get position pf next item
Select @iPos = Charindex( @Delimiter, @List, 1 )
If @@ERROR <> 0 Break
End
Return
End
FYI: I'm getting @List value from a table and passing it as a string to split function.
Any help would be appreciated!

Double click and get and store the value in variable.

Hi,
My intention is when i double click a particular record on a tabular, i want to capture or store the particular value of record into a variable and call that variable in print/preview button PLSQL code.
Below i show the screenshot which contain a tabular and print preview button. After populating the data. the user will double click on the agent code LC354 and click the print/preview button it should display report for only the
agent code of LC354(this is what i want). But normally when i click the print preview button it wil show the report of agent code of LC354 and LC325(this what i dont want).
http://imageshack.us/photo/my-images/811/printpb.png/
My problem is how to capture the value((*LC354*)) of particular record after double click the agent code(*LC354*)?
i tried to store agent code in variable AG_CNT in mouse double click trigger with following plsql code. but it dosent work.
declare
AG_CNT varchar2(10);
begin
*AG_CNT* :=GET_ITEM_PROPERTY('RFQ_AGENT_DETAILS.AGENT_CODE',CURRENT_RECORD);
end;after that pass that AG_CNT value in *:AG_CODE*. below code is in print/preview button.
cursor c1 is select nvl(count(ENQUIRY_NO),0) from scott.EXP_QUOTE_STATUS
where ltrim(rtrim(upper(job_status))) like 'APPROVED%' and ENQUIRY_NO = :REQ_FOR_QUOT.ENQUIRY_NO
AND AGENT_CODE=*:AG_CODE* ;how to do this?
skud.

Hi skud
i juast want to store the agent code to variable.if i did get ur point...
Why don't u just use a simple assign statment for example...
DECLARE
V_VALUE NUMBER;
BEGIN
V_VALUE := LC354 ; -- IF it was a value as LC354 static i mean
-- or u could use any value
V_VALUE := :ur_form_item_name; --- if it was dynamic
END;That's it .
Hope this helps...

How to print/post double-quotes on reportserver

Hi, I am using rwservlet and cannot send double quotes. I can escape single quotes with another single quote, but double doublequotes do not work. I have tried url-encoding and html encoding, and even their combination, but report server just refuses to generate the PDF with a string with a double quote.
this is my URL:
http://rs-server:7778/reports/rwservlet?cmdkey&report=somereport.jsp&desformat=pdf&TESTSTRING=aaaaaaaa&destype=cache&ACTUSER=19
now I would need in TESTSTRING to have double quotes

Non-PostScript printer - you'll need to buy a PostScript RIP, or perhaps use Acrobat Distiller to convert the PostScript to PDF, then print the PDF with Acrobat's API - see the Acrobat SDK. (This is not possible with the free Reader).

Double clicking on a region to open it no longer works...

After installing OS 10.8.2 I have problems with Logic 9.1.8. If I double click on a region in the Arrange window, it used to open on the lower part of the Arrange window so I could edit notes, velocity settings etc. Now, when double-clicking, the lower part opens for very short time (0,1 second) and then disappears. I have deleted prefs files, restarted the iMac etc., but nothing helps. - What should i do? Is there any other way to open a region in the lower part of the Arrange window?
I just discovered that I have the same problem when double clicking on instruments. They open for a very short while (0,2 sec) and then close. This means that I can't adjust parameters in the pop-up window (instrument, filter etc.). Very strange. I remember I had this problem some weeks ago, but it disappeared. Not now.

A few ideas..
Have you checked your mouse/trackpad settings in System Preferences.... in case something got messed up there... as it sounds like an input device issue in some ways
Also, check Logic Preferences/General/Editing and make sure that Double Clicking a Midi region Opens... is set to Piano Roll (Even if it is.. try unchecking it.. close prefs.. and recheck it again..)
Finally, you said you had trashed the pref files.. which one(s) did you trash? Did you also trash the CS one too.. as it could be related to a control surface issue.. I mention this because a client of mine had an issue after installing an iPad Controller for Logic... If you have an iPad/iPhone.. make sure the iPad/iPhone is powered off (Not just asleep) and test after that too...

InDesign crashes every time you double click to open an .indd file on Windows system

InDesign crashes every single time you double click to open an InDesign file and has done so since replacement of the original version of InDesign introduced in the Creative Cloud launch. Does anyone else have this problem? I'd say it was unique to my system if I hadn't experienced the issue repeatedly on several different systems now. You have to relaunch InDesign which then opens the file from recovery, so it saw the file you tried to launch in the first place. This leads me to believe the problem lies with the file association registry of InDesign inside Windows systems. I find it unbelievable that this problem still exists and remains unreported and that a solution hasn't been implemented by Adobe to rectify the issue.
The double click is a fundamental tenant of opening files on a Windows system in the same way a single click is on a Mac. Does InDesign crash ever time a Mac user clicks to open their files, I think not.
Anyone got any ideas other than the obvious which is Adobe actually got their figure out and fixed it.

Hi Michael,
I'll give it a go. Don't really like messing with the registry on Windows boxes. Yes you can do it, but it can end up being a case of the operation was a success, but the patient died.
Just was rather hoping someone else had already experienced this problem and posted the registry tweak. Didn't want spend hours reinventing the wheel. Not because I'm lazy, but I have so many demands on my time that resolving a minor issue that effects me only seems like it should be pretty low priority.
The system I'm using is brand new, but the problem seems to have followed me regardless which may indicate that it is seated in my synchronization information somehow. Really don't know how that could happen as I'm not an Adobe engineer or have the remotest idea where to even start looking. So I think I'll mark your suggestion as the "Answer" and just learn to live with it.
Windows eh! Can't live with - can't live without it. I'm sure Mac can be just as temperamental. Just have to chalk this one up as being just another ghost in the machine.
Thanks for all the advice you have kindly offered, much appreciated.
Cheers,
Pat Doyle
