JavaScript Rounding Error
I have the following: DueEmployee.rawValue = (Math.round((((TotalPaidEmployee.rawValue - Advance.rawValue)*100)))/100). When the input to this is 17.205, I am getting 17.20 instead of 17.21. The function seems to be working fine for the rest of the values.
Some specifics on the fields the Data Pattern is set to num{($z,zzz,zz9.999)} on the TotalPaidEmployee and on the Advance is set to num{($z,zzz,zz9.99)}
Please the formcalc round function discussed in this thread:

JavaScript Runtime Errors in init.debug.js
I have a custom branding solution for a SharePoint 2013 site collection in Visual Studio. When I navigate the site collection or debug the solution, I seemingly randomly get Unhandled Exceptions in the /_layouts/15/init.debug.js. It's rather
0x800a03ee-JavaScript runtime error: Expected ')' or 0x80070005 JavaScript runtime error: Access is denied. The first error occurs just navigating the site collection. The second error occurs when I hover over the name with presence
at the bottom while editing an item. I haven't edited this script at all, so what can cause this JavaScript that is in the hive to throw exceptions, and what is a good approach to debug it in order to get to the root of the problem?Thank you for your response. I'm in a SharePoint 2013 development environment using IE10. When I added the site collection as a trusted site in the local intranet zone in IE 10, I no longer get the JavaScript runtime related to the name of presence
and Access. When I deploy the solution, I do not get any errors. But if I debug in Visual Studio, the solution, which is set of features that installs a master page with custom navigation, I get this error when I navigate the site collection:
Unhandled exception at line 6784, column 13 in layouts/15/init.debug.js?rev=z/JdnR/rlmz5Wvyfz5qrBg==
0x800a03ee - JavaScript runtime error: Expected ')'
The error occurs in NotifyScriptLoadedAndExecuteWaitingJobs in init.debug.js, and the call stack goes back to DeltaManager$_ScriptLoader in start.debug.js and eventually to the browserHandler, ScriptResource.axd.
init.debug.js, correct me if I'm wrong please, is a JavaScript that SharePoint adds during debugging. If I go in the hive and add that ')' where it breaks, then everything breaks. Why is this error thrown, and what is the rev parameter at the
end of the query string?
The custom master page in the solution being installed has a line:
<
asp:ScriptManagerid="ScriptManager"runat="server"EnablePageMethods="false"EnablePartialRendering="true"EnableScriptGlobalization="false"EnableScriptLocalization="true"/>
I added ScriptMode="Debug", and the errors occur during debugging. I changed it to ScriptMode="Release", and still got the same errors.
I'm not sure if and where in the code things are breaking, but I'm having trouble understanding why SharePoint, Visual Studio, and Internet Explorer behave in this manner. -
hello,
I understand that rounding errors exist and I need help determining the best way to handle them. The particular situation I am dealing with relates to finding the equation of a line and comparing the calculated values to a data set.
The big picture: I have a data set that looks generally exponential with sharp peaks along the curve. The exponential part is background noise that I want to eliminate. After trying various methods, I've determined that getting a convex hull is the best method of eliminating the background noise. The convex hull is found by finding a line through point A and point B of the data and determining if all of the data is above (greater than) the line (similar to a tangent line). Once a point B is found which satisfies the condition, point B becomes the new point A and a new point B is looked for.
I compare the data set to the points that create the line. The X values of the data set and the line are the same integer values. The Y values of the data set are DBL. I have attached a VI demonstrating the simple calculations I am doing to find the Y values along the line. It is simply the (y1-y0)/(x1-x0) to get the slope and using the slope to find the y-intercept (b = y0-m*x0). I then use the slope and y-intercept to calculate the Y values along the line. I subtract the line Y values from the data set Y values and check if they are all positive. If they are, then I can conclude that all the points are above the line and the point B (x1,y1) is kept as part of the convex hull.
The problem is that rounding error is causing "false negatives." In other words, the rounding error is causing the actual and calculated (through equation of line) y1 to be different. Since (x1, y1) is a data set point that defined the line it should be equal to the calculated (x1, y1), but the rounding error is not allowing that.
Currently, I am adding a very small (1.5E-12) constant to the data set point to account for the error and prevent false negatives (which would be the existence of a negative difference, when it should be 0). However, this small number is not always sufficient.
How can I find the maximum error, so that I can add the error to the data set point and therefore always prevent false negatives?
Thanks!

Rounding Error Example.vi 13 KBHi Lynn,
Thanks for your help.
I have attached a text file with example data set. The range is 0-6000 (look around x=187 and x=300 for max). There is a middle region (220- 260ish) that is irrelevant, otherwise, there are eight peaks in total, four peaks on each side, which are symmetric from the center. I am doing the convex hull on each half of the data. The data set actually begins as an x-ray diffraction image (irrelevant region is the backstop preventing the x-ray from saturating the detector so only the diffraction is captured) of which I take an ROI and sum down the columns. The result is this data which is pixel location and summed pixel values. (Yes, I know the x values in the text file are not integers- this is because some of the end points and the irrelevant area is extracted out and the ramp function is used to create new x values even spaced between the new beginning and end of the data set. This part of the code is inherited and I need to check with the programmer why this method was used)
Previously, I tried doing a curve fit of the whole data set (background not subtracted) with the background described as h0+h1*exp(-h2*(x-r))+h3*exp(-h4*(x-r)) and the peaks described as a convolution of a gaussian and lorentzian peak: abs(a0)*((1/(1+f^2))*exp(-((x-(r+d0))/w)^2)+(1-(1/(1+f^2)))/(1+((x-(r+d0))/w)^2))
where
r is the theoretical median of the data (point about which the image is horizontally symmetric)
a0 is the amplitude of the peak
d0 is the distance from symmetric center to the center of the peak
w is the full width half max of the peak
f is a factor to determine if the peak is more Gaussian or Lorentzian
I added the background model with the peak models (subtract d0 from r for the symmetrically equivalent peak) and used the Non-linear Curve Fit VI to fit the equation. The results were decent, but the convex hull -> subtract background -> peak fit method seemed to be fitting the peaks better (correlation .999 vs .99), which is the important part.
Thoughts?

Rounding error in BAPI_PO_CREATE1 Function module
Hi experts ,
In my project there are two steps behind PO creation 1-> Authorization of po creation And 2-> PO creation.
In authorization a logic in smart form calculates the amount for which the po is to be created and then goes go 2 nd step.
before creating po gross discount percentage is calculated the same way calculated in step1.
But at the end total amount in smartform and total amount of po created is differing by max of .01 to 0.1.
Unfortunetely the Z logic in the smartforms is caculation the creec value but standard BAPI BAPI_PO_CREATE1 is creating some rounding errors .
Please suggest some thing for this problem.
Thanks in advance

I've been working on an egyptian fraction program and for some reason I cant seem to figure out a way to fix this rounding error. An egyptian fraction is a fraction that can be expressed as a sum of fractions eg. 3/4 = 1/2 + 1/4. For some reason on certain fractions it rounds up and skips the correct fraction to subtract. When I run 2/7 its supposed to equal 1/4 + 1/28, but gives me 1/4 + 1/29 and decides to round. This is my code for the problem.
public class EgyptianFraction{
private static double epsilon = 1.0e-7;
public static void main(String args[]){
greedySearch(2.0/7.0);
public static void greedySearch(double fraction){
for(int i = 2; fraction > epsilon; i++){
if(fraction - (1.0/i) >= 0){
fraction -= (1.0/i);
//*****Output******
//0.0357142857142857 - 0.03571428571428571 = -1.3877787807814457E-17
}When I print out all of the math involved it says that it gives the output above. They are fairly close but for some reason it makes the 1/28 bigger then the current fraction. The program should subtract 1/28 and then the fraction should be close enough to 0 and end. Is there any way you guys can think of to fix this problem?You have given the error as epsilon, so you can't expect `fraction - 1.0/i >= 0` to give an exact answer.
Given your error is +/- epsilon, this expression should be
fraction - 1.0/i >= epsilon || fraction - 1.0/i >= -epsilon
or just
fraction - 1.0/i >= -epsilon
If you change this you get 1/4 + 1/28 as the answer, -
Tables and Rounding Errors on Board Game Gui
Hello,
So I am in a software development class , and my team and I are developing a software version of a board game that uses numbered tiles placed on a board in a somewhat scrabble-esque way.
Here is a picture of the game board:
[http://img90.imageshack.us/img90/1052/untitledqv3.png|http://img90.imageshack.us/img90/1052/untitledqv3.png]
Currently, a problem that we are working on is that as the tiles get further and further away from the center of the board, they are displayed further and further askew from the board lines. I have another picture to demonstrate what I'm talking about more clearly.
[http://img225.imageshack.us/img225/4605/untitled2nn0.png|http://img225.imageshack.us/img225/4605/untitled2nn0.png]
As the tiles get further away from the center, they are displayed more askew.
We think that this happens because we are using a gridbag layout to add tile objects to, which displays the tiles in a certain spacing and orientation, and then we draw the board ourselves. When we draw the board, we get rounding errors inherent in the use of ints, and the lines become a bit off, with the problem getting worse as it gets further and further away from the center.
Here is the code that we use to initialize the layout and add the tiles to it:
//set the layout
setLayout(new GridLayout(7, 7, 7, 7));
//initialize the array with the references to all the tiles that we are going to add
//to the layout
squares = new SquareView[7][7];
for (int i = 0; i < 7; i++) {
for (int j = 0; j < 7; j++) {
//create the tile, put a reference to it in the array
squares[i][j] = new SquareView(boardModel.getSquare(new Point(j, i)), listener, handler);
//add the tile to the layout
add(squares[i][j]);
}And here is the code that we are using to draw the lines for the board:
GridLayout layout = (GridLayout) getLayout();
//getting the dimensions of the board
int rows = layout.getRows();
int columns = layout.getColumns();
int width = (getWidth() / columns);
int height = (getHeight() / rows);
g2.drawImage(backgroundImage, 0, 0, getWidth(), getHeight(), null);
for (int i = 0; i < 8; i++) {
// Vertical lines
g2.drawLine(i * width, 0, i * width, rows * height);
// Horizontal lines
g2.drawLine(0, i * height, columns * width, i * height);
}I think that our problems come from the innacuracy of ints, but if there is some addition or subtraction trick that we could pull, then let me know.
Also, I was sort of looking into tables, and I was wondering if maybe we could use tables to do this, and have Java do our resizing for us.j.law wrote:

g2.drawLine(i * width, 0, i * width, rows * height);
// Horizontal lines
g2.drawLine(0, i * height, columns * width, i * height);
}I have no idea of this will improve things, but what about:
GridLayout layout = (GridLayout) getLayout();
int rows = layout.getRows();
int columns = layout.getColumns();
double width = (getWidth() / columns); //** how about using doubles here
double height = (getHeight() / rows); //** how about using doubles here
g2.drawImage(backgroundImage, 0, 0, getWidth(), getHeight(), null);
for (int i = 0; i < 8; i++) {
// Vertical lines
g2.drawLine(i * width, 0, (int)(i * width), (int)(rows * height)); // and casting?
// Horizontal lines
g2.drawLine(0, (int)(i * height), (int)(columns * width), (int)(i * height));

Jquery in background task JavaScript runtime error: 'window' is undefined
How do we access the window variable in backgroundtasks ?
i need to use jquery and i get JavaScript runtime error: 'window' is undefinedIt looks like jQuery is not written to be used from a web worker--or else you need a variant that is. This is because the global context in a background task written in JavaScript is
WorkerGlobalScope (see
http://www.w3.org/TR/workers/#workerglobalscope) not window, so window
isn't defined.
You might be able to work around a situation like this, depending on what is needed from
window. (I'm assuming jQuery is trying to initialize its UI libraries, in which case you probably won't be able to do that from a worker/background task. They can't do UI directly.)
If you need something from window, specifically, your running app, when it registers the background task, could also write the necessary values into the
Windows.Storage.ApplicationData.localSettings container as background tasks can access that at any time.
It could be possible, then, to write the necessary values from window
into local settings, then create a window object and populate it with those values before loading jQuery. It'd be a hack, but might get you where you need to be.
That said, because there are limitations on what you can do from a background task, and how long you can run, you might ask whether jQuery is really buying you anything in that context. I can't say, of course, but it's a reasonable question to ask before
trying this kind of workaround.

Perhaps there is a data error. Check your table admin_tab to see what values are being stored there in production. You're getting an error due to an unexpected value in admin_tab_line-kind. If you can't easily get to the data in the table, try debugging your program by placing a break point in the code just before your CASE statement. Then when it hits that break point, check the values in admin_tab. I hope this helps.

Hi everybody,
how should I/can I handle rounding errors in Oracle.
I'm using the LOG function of Oracle and for SELECT LOG(2,16) FROM DUAL; Oracle returns 3,99999999999999999999999999999999999998 which is incorrect. I cannot use the Round-Function cause my whole mathematical expression (written in Excel Syntax) is:
FLOOR(LOG(x; 2); 1)
So if I use the round function and SELECT ROUND(LOG(2,15)) FROM DUAL; would return 4 which is not correct thinking about my FLOOR(4) => 4, but the result of the mathematical expression is 3!
Any ideas on how to deal with such problems... is there somehow a datatype to use?

Thanks Max - I guess you just wanted to illustrated the problem? cause I don't see a solution there...

Maybe another question should be asked :)... can you count on this rounding error? I mean if so, than I could add 1 => FLOOR(LOG(2, x + 1)), but if I cannot count on this rounding error, than there could be wrong results if e.g. Oracle returns the correct value!I just showed the parameter usage of round, which you can use for rounding the digits.
While comparision like round(somevalue)>=2 as you said it is not required to round the digit, you can directly do the
somevalue>=2
But when you want to show the o/p to an end user who doesn't need 30+digits of precision, for him you can show using the above round function.
