I'm not sure you appreciated the significance of the questioner's Bankers' Rounding Function. You've given an excellent example of how this works. Using banker's rounding instead of primary school mathematics teachers's rounding on your figures, your first dividend, 0.56595, would round to 0.56, not 0.57 (with no change to the other figures), and the total of the rounded values would be the required $5.39.

Re: [libreoffice-users] Base PostgreSQL Transactions
Let me start by saying that I am not a DB expert and, although I have done significant work using DB and using transactions, I have not done so using Base or LO in general. More comments in-line. On 07/19/2013 04:31 PM, Don Parris wrote: I had hoped I would find a tutorial something along the lines of: We're going to create a way for users to enter/update data across a few tables in a single transaction. Here's how you do it using macros/BASIC... Here's how you do it using the DB's native capabilities... In order to stop our form from entering the data into each field as we type, we need to do so and so... Now to collect all the data and click submit... For all of my use cases, none of this has mattered, so I never considered it. I assume that you need to set autocommit to off on the connection. setAutoCommit(False): Enable (True) or disable (False) a connection's auto-commit mode. In auto-commit mode, all SQL statements are executed and committed as individual transactions. Otherwise, SQL statements are grouped into transactions that are terminated by a call to either commit() or rollback(). A commit occurs when a statement completes or the next execute occurs, whichever comes first. If a result set is obtained, the statement completes when the last row from the result set is retrieved or the result set is closed. So, I assume that you would simply set auto commit to false, and then, when you are finished, call commit() on the transaction. Sadly, I have no idea at all if the Form's behavior will over-ride what you do and issue a commit as you fill in each sub-form. I have no idea if you need to consider Deferrability in all this (deferrability is related to foreign constraints). How does one prevent the form inserting the data on the fly - do I use a macro? Should I write a function or procedure on my PGSQL server to run when the user clicks Submit in the base form? And how do I get the Submit action down to Postgres to run the transaction procedure? I get the commit() function ( http://wiki.openoffice.org/wiki/Documentation/DevGuide/Database/Using_DBMS_Features). .. But isn't there a BEGIN statement? I think what I will do is move my DB forward at its current level and read up on transactions, triggers and procedures - as well as on LO Basic Macros - so I can implement the transaction stuff later. I bet it's a lot simpler to understand than I think. But having to look in 20 different locations for little pieces of info - and then figure which pieces go where in my problem is more than I really have time for right now. If when I do figure it out, I'll have to write a tutorial on it for sure.

[libreoffice-users] Re: Visible currency rounding
You described it in the most precise way. I needed a function that would round down the number if the followin digit is less then 5, and would round up if the followin digit is greater then 5, and if the followin digit is equal to 5 then it will test if the last digit to remain in the number is odd or even and then round it up if it is odd or leave as it is if it is even. I think this is called Round half to even as a tie braking rule. But even more accurate description is here: http://www.xbeat.net/vbspeed/i_BankersRounding.htm I must confess I did not have an idea that this was called Gaussian rounding. In my case the function needs to start from the least available right standing digit for the given number and round consecutively from there to the left untill the desired digit position is reached, one digit at a time . This way it ensures that any boundary cases be treated correctly. The practical need for this is when I had to fill in an invoice, on each row I wold have an intermediate number which is a result of multiplication of amount by unit price (i.e. an item's sum), which in the general case will not be an exact number . Then I would need to round this number to a sensible (currency) format and only then to add the numbers up in order to get the final amount for the invoice. In this way all numbers add up correctly and there is no difference in the final amount. As for the example where 23,574 rounds to 23,57 , this is the intended result as described above. Thanks again for the clarification you've given in your post.

[libreoffice-users] Re: Visible currency rounding
I have given my reasons in an explanation to a post by Luuk in this present discussion. But I think this is not an overkill, because if we have a significantly long number and we just look at the 3 digits to the right of the comma separator and just drop the rest of the digits to the right of them - we shall be risking to get an incorrect result. The correct way to round the number will be to start at the rightmost available digit and drop one digit at a time, untill we reach the desired digit position. At least this is correct in my oppinion.

The correct way to round the number will be to start at the rightmost available digit and drop one digit at a time, until we reach the desired digit position. At least this is correct in my opinion. Paradoxically, this is certainly not the way that rounding - even banker's rounding - is normally achieved. You would round 1.23456 to 1.2346 and then to 1.235 and 1.24 (using either scheme). Single rounding (again using either scheme) gives 1.23. This makes sense, since the original number is clearly closer to 1.23 than to 1.24. It is a general principle that you should always round numbers once; if you do so repeatedly, you will indeed get different results. http://en.wikipedia.org/wiki/Rounding#Double_rounding says: In _Martinez v. Allstate_ and _Sendejo v. Farmers_, litigated between 1995 and 1997, the insurance companies argued that double rounding premiums was permissible and in fact required. The US courts ruled against the insurance companies and ordered them to adopt rules to ensure single rounding. Some computer languages and the IEEE 754-2008 standard dictate that in straightforward calculations the result should not be rounded twice. This has been a particular problem with Java as it is designed to be run identically on different machines, special programming tricks have had to be used to achieve this with x87 floating point.[...] Brian Barker -- To unsubscribe e-mail to: users+unsubscr...@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted

[libreoffice-users] Importing image from LO Draw (ODG) to Writer
I had a one page PDF file that I wanted to break into multiple pages. Opening the PDF with LO resulted in LO Draw opening with the file nicely displayed. I saved it as a draw image (odg) and then expected to be able to directly import it to Writer. Unfortunately I could find no way to do that. Even using copy/paste resulted in a black page since the image was larger than one page. My hope was to have it come in and naturally break into multiple pages. As a last resort I selected a portion of the image in Draw , copy/pasted it into Writer, inserted a page break then repeated the action on multiple pages until the entire image was in Writer. It seems as if there must be a more elegant way to do this. I have never used Draw before so I'm just trying to figure out the details. To be useful it seems as if there must be an easy way to move from Draw into Writer or Calc. Can someone help me see what I'm missing? Thanks.

[libreoffice-users] Augmented Matrix in Math
All,
I am trying to create an augmented matrix in LO Math.
(http://en.wikipedia.org/wiki/Augmented_matrix)
The code below generates a regular matrix. To make it an
augmented matrix I need a vertical line between the 3rd and
4th columns.
left [matrix{1#3#2#4##2#0#1#3##5#2#2#1}
right ]
I've had no luck with lline and riline.
The vertical line can be solid or dashed, and I'd like the
option to use either so I can choose the one that looks best.
Thanks,
-Bill
