• do not take into account the negative numbers

  I have a column of numbers I would like to add, but I want only to add positive numbers and ignore the negative numbers. How to do?

  I suggest that you use SUMIF.

• Spot calculate modulo of negative numbers incorrectly

  I'm a math major Bachelor's degree. Sometimes I use a projector to check my calculations. However, when calculating the modulo (%) negative numbers by using spotlight, the calculator returns inaccurate answers. I was wondering if anyone else has noticed this, or why it could be (apart from the bad coding)?  For example, it returns,

  -2 %3 =-2 and -1 = - 1 %3.

  However, if you were to Google "-2 %3 ', or calculate this in Wolfram Alpha, R, C, Python, etc. you see:

  -2 %3 = 1 and -1 %3 = 2.

  These are indeed the right answers like:

  -2 = 3*(-1) + 1et -1 = 3*(-1) + 2

  I submitted via the official channel on this subject, but I thought I'd post here to draw attention to the problem.  I hope Apple solves this problem for the large number of students who use their products is not misled.

  It depends on the definition of the % operator. You expect it to be an operator "rest". Spotlight uses the same library as Xcode which defines it as a true modulo operator.

  See here for the definition of the module: http://mathforum.org/library/drmath/view/52343.html

• PXI-8433 (RS485 or RS422)

  Hello

  I use NI PXI-8433/2 Board for both interface RS422 and RS485.

  It seems the two ports are set up RS485 only.
   
  Could I use one port(for example : COM8)  for RS485 and one port((for example : COM9)for RS422?

  If it's possible, how (and where) can I set up for them separately?

  Thank you

  Insuk

  Hi Insuk,

  If you set the 4-wire RS-485 port, you can connect an RS-422 interface. I don't know if the Board can handle full-duplex, maybe not important for your application.

• String to the Array.vi worksheet with negative numbers

  I was exploring a program posted on the developer zone titled "ClipboardtoNumericArray.vi" and noticed that it substitute 0 for elements with negative numbers. The 'String to Array.vi worksheet"working with negative numbers? If so, how?

  The problem is that your negative sign is not a negative sign.  This is the code ASCII 150.  I'll call it something like a "long dash", that's why it does not recognize the LabVIEW code.  A negative real sign you have in part E-6 is code ASCII 45.  And also why same Excel treats as text rather than a number.

  Where did you get the CSV file from?

• How do you know if there are more positive or negative numbers?

  I'll try to explain my problem with an example, because I do not have labVIEW installed in the computer.

  I have 10 numbers and multiply to 10 other numbers

  and of course I get 10 results, after I have to show the value of meddium of this 10 results and must show the signal that most seem (+ or-)

  My problem is to show the signal, if I have 7 positive 3 numbers and negative numbers, how to measure and display the negative signal to the final?

  example:

  -0,3-0,8 1 0.3 0.6-0.7 - 0.1-0.5 0.3-0.4

  If I have to put in the final:

  -0.5

• Right axis graduations and negative numbers

  Has anyone else noticed that when you have a Y axis on the right side of a graph and showing ticks, it can be confusing because positive numbers look like negative numbers?  I played a bit with custom formatting, numbers, such as adding space before the number.  Other known improvements?

  Thank you

  You can change the color of the labels. That could make it a little clearer that it is not negative.

• How to fix negative numbers in images u16

  Hello

  I have a 2d chart which is u16 (0-65 K) and trying to avoid a 'dark' of him. The problem is that it sometimes gives way to negative numbers and he made a wrap-around and shows the values as 65 K. Is there a function truncate or something to make them void. Sorry if this is a simple question. I only did labview for a few weeks.

  Thank you

  imageproblems,

  Have you considered casting the U16 to I32, making your subtraction, compel the value such that it does not fall below zero and ultimately return to U16 castant?

  I don't know, but it might work for you...

• What isolation on the NI PXI-8433/4 map put in place

  We anticipate using an NI PXI-8433/4 card installed in a PXI-1042 chassis to read the data of four RS-485 serial data links.  Each of the serial data links we read have their own common isolated which is not related to the municipality of any other channel.  In addition, the common and common receiver for each binding of data is linked together.  Bascially, we read each of the four serial data links are completely isolated from each other, but the transmitter and receiver ends for each binding of data have their common tied together.  A pictorial representation of our Setup is attached.

  We found that this article on how opto-isolation is implemented on other serial acquisition cards:

  http://digital.NI.com/public.nsf/allkb/4A380A17DB3D9EF086256C68006F1DCB

  This article basically says that the i/o lines are isolated, and the power of the transceiver is isolated by a transformer.  This is how the make isolation is implemented on the NI PXI-8433/4 map?  We do not want the transceivers in the PXI-8433 card to link the municipalities of serial data link.  Thus, we require each transmitter/receiver to have its own common isolated, and so it is own isolated power source.  Each of the transceivers are in the PXI-8433 map completely isolated from each other, including their common/reference?  Thank you very much for the help.

  Hello

  That Board uses digital, through means of conversion continued isolation to isolate each part of the other and the rest of the PXI chassis. That said transceivers will be isolated from each other.

• Y at - it a number of RTF format that displays negative numbers in parentheses in Excel?

  Hello

  I have an RTF template that formats a report to output HTML, PDF, Excel and Excel2000.

  I want to see negative numbers in square brackets, without a hyphen, by example-2568 as (2568) for the purpose of accounting reports.

  I tried different solutions to this problem that I found,

  #, ##0;(#,##0) is not good because it only works in HTML or PDF format

  #,##0_);" (« #, ## 0 ») "also not good that the format does not seem to be recognized.

  I saw another post that is to make a conditional script on the number and the concatenation in brackets, but I can do it in SQL cast to varchar type data extraction, treat numbers as strings.

  Is there an identifier of real formatting which works in all types of output files or is it a feature not supported?

  Thank you and best regards,

  Phil.

  Did you try to use the Force LTR and select the type as text. (assuming that the value in the XML file is "(2658)")

• How to set the {} num.currency such way that it will display "-" sign for negative numbers instead of "()".

  Hi people from Adobe,.

  I am working on a form of invoice of Adobe, where currency a few fields may show as "-" if it is the negative number.

  I use display model num.currency {}, but its poster ($1,234,567.89), I want to display in the form $-1,234,567.89

  Is someone can you please let me know how to achieve this.

  

  

  Hello

  I wondered if it would be that simple.  It seems that the United States and Hong Kong are the only ones who use the media for negative numbers.  The Australian currency displayed as you wish.  Maybe you can go into the XML Source and change the line $z, zz9.99 | () $z, zz9.99) $z , zz9.99.  This is how the Australian looks... would need a few tests well.

  Or maybe you can have the hidden decimal field and display a text field with a calculation as DecimalField.formattedValue.replace(/[()]/g,"");. " Do you need to align the decimal points?

• Exclude negative numbers?

  Is it possible to exclude negative numbers appear in numeric fields (currency)?

  For example, if a user tries to enter a negative number in a given area, is there a way to tell Adobe to clear the entry, or, better still, to prevent the user to do?

  Thanking you in advance.

• A character style that puts in shape all negative numbers (-10) with red color

  How to set a character style that formats all negative numbers (-10) with red (a predefined text style)?

  I guess that I should be using GREP, but it's kind again for me and I can't find an answer to this on google.

  -\d+?,\d+?\%|-\d+?

  seems to work

  GREP is synonymous with General Regular Expression Parser - large print receive codes and you insert the code to highlight the characters you want to

  In the that I provided above is probably not the nicest way to do it, but I'll break it

  -= minus sign

  \d = any digit

  + = Continue until there are no more numbers

  ? = off at the end of a group of numbers

  This means find any number within a group of numbers

  just means a comma

  and yet once I wanted to find any group of numbers with \d+?

  % means with a percentage at the end sign

  -\d+?,\d+?\% means find: sign, followed by a group of digits followed by a comma followed of another group of numbers followed by the percent sign.

  | [vertical] means OR

  -\d+? would be to find a

  -

  Group of figures

  -\d+?,\d+?\%|-\d+?

  All means find any group of numbers separated by a comma with a sign of percentage at the end OR a sign less with a group of figures.
