• accuracy of digital data from LabVIEW

  Hello!

  I have a question about the accuracy of data, Labview, is perhaps a silly question, but it drives me crazy.

  If I use a digital constant and I put for example 1 (I mean 1E-6), it looks like 1E-6 but I found that it is not really 1E-6, actually if I raise the precision and I use 17 digits, 1E-6-9, 9999999999999996E-7.

  Could someone explain to me what is happening for digital data?

  Thank you

  It is one of the most frequently asked questions ever.

  The trick is in how computers represent floating point value. I remember a lot of right answers already given in the forum, but I am not able to find the most comprehensive and clearest.

  For example, one of the answers is here.

• Obtain the string of digits: numbers 4 and 5 DNs

  Hello

  I have a dial plan with 4 digits of 2000 to 8999 DNs and DNs 5 1XXXX numbers. I have a request of CIM which invites the appellant "If you know your party's extension number, dial now."

  In my script, the 'Get string' is configured with ' # ' to end key and number of digits = 5. The problem is that when a caller dials a number of extn 5 digits followed the #, it is not to transfer the call, but repeats the prompt and will eventually unsuccessful branch.

  If I do not put the end key #, when a caller dials a 4-digit extension, it is not successful either. How can I fix it?

  Thanks for your help.

  Hello

  The number of digits must be at 6, # must be included

• Skype digits / numbers online the difference?

  I iwsh to implement local numbers for Canada, Australia, New Zealand, Ireland and up to 4 in the United Kingdom. I looked at the different options, but what is the difference between number of Skype and a number online?

  Also can someone tell me the simplest and cheapest solution.

  I want to use these numbers for the recruitment of teachers.

  There is no difference. Skype numbers are just the modern equivalent. See here for available countries. You can have up to 10 numbers in any or all available countries.

• Print invoices from Xero accounting software came up with random question marks instead of digits/numbers

  Hello

  
  

  We just started to use the Xero accounting software and it generates invoices in PDF format.   When the Preview on screen before you print it shows correctly, but once printed, it prints with an exclamation mark to chance on the invoice due date, for example. May 15 201? instead of May 15, 2015.  It does this on each invoice, to calculate all in our office.  I contacted Xero and they say they produce the invoice correctly and that it may be a problem to Adobe.  When you print in overview (on mac), it prints properly but not in Adobe Reader.  Any ideas?

  
  

  Currently using Mac OS X 10.10.3, Safari 8.0.5, Adobe Reader 11.0.11 (or the previous version - I though updated might set but not luck).

  
  

  Thanks in advance to anyone who can help us with that.

• How to convert numbers to the string with an optimal number of numbers?

  Hello.

  I'm doing something that seems just, and I wonder how much trouble I have with this.  I'm sure there is a way to get LabVIEW for this.

  I have a table of numbers (double), and I use the 'Worksheet picture String' function to generate a string that I can write to a file.

  The problem I have is I want to make the chain to omit useless zeros after the decimal point, but I don't want to limit the accuracy of the numbers that requires it.

  For example, if my data is as follows:

  0.02

  0.4476

  -0.0244570001

  I would like for the string I can be exactly like what I wrote above.  However, depeding on the format string that I use, that's what I get:

  format string: %.10f

  0.0200000000

  0.4476000000

  -0.0244570001

  format string: %f (it seems that by default 6 figures)

  0.020000

  0.447600

  -0.024457

  format string: %.4f

  0,0200

  0.4476

  -0.0244<= all="" trailing="" digits="" for="" this="" number="" have="" been="">

  Anyone know what the format string should be to get the string I want to (what is this

  0.02

  0.4476

  -0.0244570001

  Thanks in advance,

  Alejandro

• fields of digital type in the table editor can be too small

  Hello

  just a minor inconvenience: depending on the settings of digital numbers may not fully appear in the table editor, refer to the figure below where a digital precision of 15 has been set with scientific notation. Of course, these values are used to display the stepsize in the editor, too... Because it is possible "scroll" the number is not a real problem, but it is not very nice either

  

  Hi Wolfgang,.

  I could reproduce this behavior here on my end. I'll take it then they can handle it for the next version of the CVI.

  Best regards

• Set the format digital u32 when writing of TDMS files

  We use two meters of a PCI-6251, with two counters in the mode of angular position, to measure the angular positions of the two optical encoders 1000 per second for intervals of 10 to 20 hours.  We are writing to write files using PDM.  The files are very large, about 800 MB, but it is acceptable.  Convert us the TDMS files in .txt files, and then the data from .txt files are analyzed in Mathematica.

  My question is: How does one control the digital format of the data that is written in TDMS write?  At this moment we have two counters of the value of the product N = 10000 numbers U32 samples are then transmitted continuously to a TDMS file every 10 seconds.  The counters are using units of ticks (integers) and we would like to see whole in our data files.  We are convinced that the counters are producing U32 to the format number, since we see the correct U32 integers in the indicators on the front panel and we see labels on the value axis on our waveform graphs are integers, not real numbers.

  But it is also clear that Scripture TDMS puts double-precision (64-bit) numbers floating point in the PDM file, not numbers of U32.  The double-precision floating-point numbers cause our .txt files to be twice as big as they should be - these .txt files are half full with useless zeros and decimal points.  In addition, when you convert the U32 to double-precision real numbers, it seems to be a loss of precision as a result of writing of PDM, which is not acceptable.

  Our experience produces pairs of integers: U32 (or I32) format.  We could even get away with numbers I16.  Is it possible to get our data to stay in U32 (or same I16) format when they are written to the TDMS file?  What controls the digital numbers written to tdms?  Do all the numbers written in a PDM file end up being written as floating-point numbers double-precision?

  We use LabVIEW 8.2 on a PC running windows XP.

  If associate you TDMS write U32 data, data in the file will be U32. Floating-point conversion probably occurs when you read data from the file back. You can change this by plugging in a U32 empty table at the entrance of 'data type' reading PDM.

  You can check the data type in the file by examining the channel properties in the viewer of TDMS files. If NI_DataType is 7, given in the file are U32. If it is 10, data are floating point.

  Hope that helps,

• precision of timestamp

  When Labview run on a pc (and not a system in real time like a CRIO), what is the accuracy of the LabVIEW release timestamp function?  I want to assure you that I understand that, when interpreting the data for a project, because I'm the time is broadcast by the timestamp with 6 digits of precision to fractions of a second (i.e. 2,0592060 seconds, it is an output).  I am trying to acquire data at a rate of 300 Hz, so it would be good to know if at least that the timestamp data are accurate to 3 decimal places for a second (2,059 seconds).

  Hi WyoEng,

  If you store values the time stamp (to get Date/time in seconds) generates in a table (if one ignores redundant data during picking too quickly) and then check the difference between the two, you will see that the result will be of 1 ms.

  Try to save the timestamp faster than 1000 Hz and you will see that you will get the same data.

  What equipment do you use the Acquisition?

  Is - this material timing? or the moment of software?

  I think that the accuracy of the numbers that you see is due to the way that LabVIEW stores the data type Timestamp-

  You can see in the LabVIEW help - (see the following link - in the section Time Stamp)

  How LabVIEW stores data in memory

  http://zone.NI.com/reference/en-XX/help/371361J-01/lvconcepts/how_labview_stores_data_in_memory/

  "

  Timestamp

  LabVIEW stores a timestamp as a cluster of four integers, where the first two signed integers (64-bit) represent the number of area — independent of the full time seconds that have elapsed since 12:00 a.m., Friday, January 1, 1904, universal time [01/01/1904 00:00:00]. The two unsigned integers (64-bit) represent fractions of seconds.

• Is it safe to delete the .dmp files in the program directory?

  I found a big enough .dmp file in my Firefox installation directory:
  c:\Program Files (x 86) \Mozilla Firefox\core.20130617.XXXXXX.XXXXX.XXXX.dmp
  It seems that the main file is labeled with a date stamp; the "X" are other digital numbers by hiding I am those out because I'm not sure they're relevant. Is it safe to remove this? Note that this file does not appear in topic: down.

  Delete it and restart the computer, make sure that firefox is not open as windows usually makes those when you get BSOD.

• Response of the keyboard to the automated operators?

  Hello everyone, I'm new here so I hope I'm not repost this question...

  I just bought a subscription to Skype and tried to make a normal call my bank where the automated operator requires a keyboard (or tone) input. I tried to answer with a keyboard and NUMPAD digital numbers but did hear no dial tone and got a request for repetition. Is there a way to respond to these operators automated by using key and how I go about this?

  Thanks for your help, Sam

  Great! That worked, but I didn't know there is a keyboard during a call on Skype interface. Thank you!

  What is the point of having a huge screen and a desktop computer if it does not open more simple spreadsheets that I used on the machine in the last two days. How should I do?

  HI Roger,

  Not enough information to give a definitive answer.

  Is the current version of the version (3 digits) numbers only you have already been installed on the Mac? (Can't even guess that, as you have sindou no information as to what model it is or the version of Mac OS X you have installed).

  If you have had Numbers ' 09 on this machine, it is probably still there, in a folder named iWork 09 in your Applications folder.

  If this is the case, one possible cause is that you try, whether intentionally or by accident, to open files in Numbers ' 09. Try to open the file by dragging the icon of 3 numbers on the platform and by the applicant on this icon. The icon number 3 is a bar chart with FOUR bars. Numbers ' 09 has a similar icon, but the bar graph has only 3 bars.

  Kind regards
