How let labview to check the string is in Scientific Notation.

Hey all,.

I want to labview to convert a worksheet string in a table. It's easy using the tool 'chain of worksheet to the table '. The only problem I have is that I get the string from a RS232 device and the critical moment arrives.

Example:

If I read the data from the buffer it gives me:

1.50337800E + 00 + 1.70316300E + 00 for both channels, it is converted and accepted

If there is a slight delay, I get:

+ 1.50337800E + 00 + 1.70316

It is also accepted because + 1.70316 is also recognized as a number.

How can program labview to check each number he reads is according to Scientific Notation?

Thank you

This regex seems to work for me, for all cases, I've tried:

[+/-]\d+\.\d+[Ee][+/-]\d+

Note that it is very restrictive and only follows the shape of ±n.nnnE±mm

  • 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,

  • How can I watch / check the status of the master file Table in XP?

    Theoretically, I have 55 G of disk space on a ThinkPad R60. I have confirmed that there is less than 24 G in the files, but Windows tells me there is only 4.5 G of free space. Who went from 250 M I had before taking the steps described below.

    CHKDSK finds no bad sectors.
    When I run chkdsk, it says it has repaired an attribute bitmap MFT error.
    In the next row chkdsk says that it has detected an "open space marked" (what it is) as he tried to complete the allocation of bitmat volume, then goes on to say that he found a problem of file system and I need to run chkdsk /f.
    Have made several times (in addition to the removal of files and programs, disk clean up, defrag and delete the old sys running restore points), but to no avail.
    Although I doubt that the MFT itself will devour that much space, chkdsk results leads me to believe that the problem could be associated MFT.
    Question: Is - everyone out there knows how to get a look at or test the validity of the MFT?

    This problem has been resolved, but I just wanted to make the new assignment to inform everyone.
    Have a ThinkPad R60 with a score of 52 gig. There was less than 24G in stored files, but I was getting Windows low disk space warnings.
    Tried everything but could not find most of the missing space.

  • Check the string only Alpha characters

    Is there a function in ColdFusion that will check that a string of alpha only characters (not digital or for example &, $, etc.)? I try to avoid creating a string of alpha characters or all all nonalphanumeric characters to loop on and the text is authoritative.

    Which could easily be done with a regular expression using REFIND() function search.

    Something like that on the top of my head and untested example.  REFIND("[^A-Za-z]",yourStringVar).  If that returns true then we characters other characters then alpha in the chain.

  • FF8.01 how can I avoid checking the add-on which appears every time I start the program?

    In Firefox 8.01, whenever I start Firefox, a box appears indicating that the program checks to see if my addons are compatible. There are currently 3 who are not, and this box simply delays the start of the program to tell me the same thing whenever I start Firefox. Most annoying. Is there any way I can prevent the display of this box, or reduce it to once a week or once a month?

    Can you check this number 9 of Firefox?

  • Check the string value when using xdoxslt

    Hello

    I'm new to the BEEP and will have questions in writing this simple code for a model RTF. In plain language, that's what I want to do:

    the value of VNAME variable FirstName + "" + name

    Finally... show the VNAME variable

    I wrote it, but it doesn't work:

    <? xdoxslt:set_variable($_XDOCTX,_'v_RTPMName',_'x')? >

    String value of control-> - error.

    Hello friends, would like to know how can we access/check the system configuration of the SX20 if we not touch and remote control or they are not in working condition.

    I think that we can check this Switch interface, but unfortunately, I don't have access to the local switch right now.

    Hello

    option is to have access to the local switch and run "show cdp neighbors detail."

    or

    Connect the mobile to PC/computer LAN, run tftpd32 with affected DHCP pool. Then you can login to get the config.
