• Mathematical functions with input/output error

  Please refer to the attached picture. Where do you find these mathematical functions with input/output error? I saw these in response to a message.

  I think they appear when you connect a waveform or dynamic data type.  Since I rarely use these data types (just give the table!), I'm not positive.

• Mathematical functions in a table

  Hi all;

  I'm building a choise multipul quiz.  There are two buttons, one with a value of '1' and the other with the value "0".  They are fed in a table called (responses).  How to add all the elements of the array, and then how do I perform mathematical functions on this new issue of analyzed the percentage of correct answers and logically if the person has passed or not

  Thank you

  James

  As I said in the first response, you can simply loop through the array and the amount that you will...

  var sum = 0;

  for (var I: uint = 0; i)

  sum yourArray += [i];

  }

• Mathematical function to show only the positive numbers?

  Does anyone know of a mathematical function to show only the positive numbers. I have a formula that returns an integer, if the integer is negative, I want to show ZERO. I'd rather not have to use a case statement.
  
  For example, if it returns 5, I want to see 5. If it returns 0, I want to see 0. If it returns-2, I want to see 0.

  How about this?

  (x + ABS) / 2

  where x is the column?

  When x = 5, you have (5 + 5) / 2 = 5

  When x = 0, you have (0 + 0) / 2 = 0

  When x =-2, you have (-2 + 2) / 2 = 0

• Mathematical function FRS

  I use the mathematical function in FRS 'PercentOfTotal([A,40],[A,39]) '. I chose to use a custom formula. But when I try to save him. He does not receive SACE and when I run web preview so I am getting error in each cell of this row.
  
  can someone help me with this. I don't know how these mathematical function work in FRS.
  
  Actally I want to perform ([A, 40] / [A, 39]) * 100
  
  Thank you

  When you select a cell/row/column formula, you should see the formula bar activate (go from gray to white) it looks like in the formula bar in Excel. There just above the POV. Either by the way, I want to talk about studio HFR, not the HTML client in the workspace. You should see (from left to right) a drop down menu where you can select different functions, then a help "?" then a red X, then a green check mark. After typing in your formula, click the green check mark to validate and "lock" function. Save your report and try to run it.

• Mathematical functions on db TinyInt columns does not work?

  I have several columns with integers stored using the SQL TINYINT data type. I am trying to add the columns and pass the average of Coldfusion:
  
  < name cfparam = "avgrating" default = "#rsgetratings.ratingone # + #rsgetratings.ratingtwo # / 2" >
  
  and #avgrating # guard display text without running the mathematical function as such:
  
  2.000000 + 2.500000 / 2

  You must put the variables in brackets, so that they are treated

  #((rsgetratings.ratingone + rsgetratings.ratingtwo) / 2) #.

• Help for writing a mathematical function

  Hello again,

  I work on a tile game and need to understand an equation... I have a 12 x 11 grid... When I place a tile, I need to check for the existence of other tiles on the same row and column and sum their values...

  I need to create an equation with the following variables: -.

  Gets a number between 1 and 132: -.

  divides or multiplies the number in all the possible divisions of 12 between 1 and 132

  Adds or subtracts the correct amount of tiles that are either dependent on its position

  (I stretched the grid and, for example, tile 66 has five tiles on each side, tile 121 a 11 to it is because it is in the lower left corner)

  Hope this makes some sense to someone... I am now starting work on it, but any help would be appreciated!

  Thank you

  F1 will return a 2d array.  the first element of array contains all members of rank and 2nd of all the members of the column.

  Function f1(n:int):Array {}
  var m:int = n - 1;
  var row:int = Math.floor (m/12);
  var col: int = %(row*12) m;
  var rowA:Array = [];
  var colA: Array = [];
  for (var i: int = 0; i<12; i+)="">

  See if this document explains your problem.

  The problem seems to be the name you gave to your variables.

  I found this after doing a search on the forums for the error code 23083.

• Text can be displayed in a column of formulas using mathematical functions?

  I work with reports financial 11.1.1.3 version and I am trying to achieve the following scenario:
  
  Column D is a data column
  Column E is a text column that contains the value "TEXT".
  Column F is a formula with the following formula: IfThen([D]=0,[E],[D])
  
  I want to see happen is if the value in column D is 0, so I want the value 'TEXT' to appear in column F, otherwise; I want to show the value of data located in the column (D) is possible to display text in a column of formulas and if so, what is the syntax for this? Or does anyone have another way to do this? Any help would be appreciated.
  
  Thank you!

  Short answer: No.

  For your question, I would say put your TEXT value in the #zero and the #missing overrides in Report Studio.

  In general, Hyeprion statement does not features or postings of actual text that you could use in Excel.

• How can I use the BCGTransform function to treat the 16-bit Image?

  Hi ~

  I use LabWindowsCVI8.5 and NI Vision to make the treatment of the Image. When I read the "IMAQ Vision for LabWindowsCVI Reference Manual", I found that the imaqBCGTransform function only supports 8-bit Image, while I do the BCG to turn on 16-bit image. Are there solutions to use the BCGTransform function to deal with the 16-bit Image? Or any other feature that could make the correction Gamma, contrast and brightness on the 16-bit Image?

  Thank you very much!

  because imaqBCGTransform is implemented as a lookup table, we can understand why it is limited to 8-bit images.

  Now let's take a look at the definition of each of this mandate (from the NI Vision Concepts documentation):

  -brightness: a constant added to the components red, green, and blue pixel of color over color, decoding of the process;

  -contrast: a constant multiplication factor applied to the components of the luma and chroma of a pixel of color in color to decoding process.

  -gamma correction: expand high gray-level information in an image while removing information of low level of gray.  (the chapter on lookup tables gives some examples of corrections gamma)

  now that you understand that this transformation is a simple mathematical function, simply calculate the correction for each pixel on your 16-bit images.

  I know not the exact formula used by the imaqBCGTransform function, but you should be able to approach by performing some tests on images 8 bits with the original function... or you can make your own formula... or find one on the net... or you can ask someone at home OR you give the formula...

• User of the RPD power function

  Hello

  I'm developing this formula in OBIEE using the power excel function.

  = ((1+11.9/100)^-0.25)*(Auth Total deles de intérêts + frais Total de Auth) ))

  = ((1 + 0,119) ^-0,25) * (Auth Total interest + Auth Total expenses)

  Can someone please help to get the right syntax. I don't know how to apply for a power of-0,25.

  
  

  Thank you
  

  Hello

  The RPD, you can use power function (it is in mathematical functions).

  For example:

  Power((1+11.9/100),-0.25) * (Auth Total interest + Auth Total expenses)

• FIRST HP: Geometry commands Tests

  Hello

  In the application, we function TEST of GEOMETRY. It is a unique but very necessary function. Let me give you an example. I draw the GD rectangle, rectangle (GA, GB, GC). Then, in the geometry view digital and I write is_parallelogram (GD). Then back to the Plot of the geometry window and enter for a vertex to change its dimensions (length and width). Nevertheless, always on the screen I have a rectangle. But on the screen TEST shows strange things. Once the is_parallelogram (GD): 1 then is_parallelogram (GD): 3. even for other geometric figures:
  Rhombus, square, triangle, isosceles triangle.
  Ill work TEST function in the construction of their own this building, where there are forms of a rectangle, square, diamond or different triangles. When we change the dynamic side of these figures we get messages wrong: is_parallelogram, is_ isosceles, equilateral is_.
  I use a lot of GEOMETRY and these false messages on the screen annoyed me. It works great the TEST function for the parallelogram of figures. It shows always, at any time, without any error is_parallelogram (GD): 1. it is similar to is_collinear (). OK, but not perfectly with the command is_parallel and is_perpendicular. It must also be corrected to make it without reservation. I have another question. Is the is_element () command is the mathematical functions only or for different geometric figures and geometric constructions.

  Best regards!

  Hello

  I'm not sure I understand your question exacly (English is not my native language), but I'll try to bring some light it...

  The is_parallelogram function can return the numbers 0, 1, 2, 3 or 4 to indicate: no parallelogram, parallelogram, Rhombus, rectangle and square.

  Go back 0 or 1 that you complain?

  In the application of geometry tests are performed on the values of the coordinates of the object floating points. Unfortunately, this leads to loss of precision which in turn throw off-label test (the value of floating points being the accupressure, the figure is only approximately parallel or rectangle). Perhaps what you are experiencing.

  If this is the case, an easy solution is to change the setting of case epsilon.

  To compare 2 numbers, system of computer algebra (which is the calculation behind the application of geometry engine), subtract them and test if the result is smaller (in absolute value) to epsilon. Change the default 1e-12 1e-10 Epsilon (in CASE settings, page 2: update, Page Down).

  This fix works because, to test if 2 lines are parallel, the CASE will calcualte their relative angle and then compare that angle with 0 (or 90 to perpendicular). Which will make the more lenient number comparison will make the geometry to test also more linient.

  I hope this helps.

  Kind regards
