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

  • How to group and summarize the values with a vertical drop of 100?

    Dear gurus
    How to group and summarize the values with a vertical drop of 100 as the data indicated below:

    Cas_Cod_ Cas_Amt_ Description
    300 1000A
    301 200 B
    302 350 C
    400 500 A
    401 100 B
    402 25

    Now the data should be grouped like this
    A (300,400) = 1500
    (301,401) B = 300
    C (302,402) = 375

    Make sure that I don't have a column as description in my table to group data on description, its here just to give u an example.

    Hello

    using mod for hundreds:

    with x as
    (
      select 300 code, 1000 amt, 'A' descr from dual union all
      select 301 code, 200 amt, 'B' descr from dual union all
      select 302 code, 350 amt, 'C' descr from dual union all
      select 400 code, 500 amt, 'A' descr from dual union all
      select 401 code, 100 amt, 'B' descr from dual union all
      select 402 code, 25 amt, 'C' descr from dual
      )
       select mod(code,100) code, sum (amt)
        from x
       group by mod(code,100);
    

    Using the mod you get the rest of a division, so mod (300,100) = 0, mod (301,100) = 1, etc.

  • How to convert the string with numbers in the table of Boolean 2D

    Hello

    I have input a string with comma separated numbers 1,192 (starting at 1).

    This string must be converted to a table 2D-boolean. Each number that appears should be true, not true rest.

    The 2D table consists of 4 times of 0.47 Boolean values.

    1.48--> [0.47] numbers [0]
    49.96--> [0.47] numbers [1]
    Numbers 97.144--> [0.47] [2]
    145.192--> [0.47] numbers [3]

    If a '1, 49, 97 145' input string put all [0] [0.3] true.

    How can it be easy/fast resolved?

    Thanks for help

    Break the string of numbers in a table of numbers.  (Spreasheet String to Array).

    In a loop For, index with each issue of this table.  Use in the range and Coerce to see if it is in the range of numbers.  (You can put this in a loop For as auto good indexing through the ranges).  If it's in the range, then use subset replace table to activate the corresponding item in a real.  If this is not the case, do nothing.  Maintain the table of Boolean in a shift register.

    Repeat this step for each number in your table.

  • How do to convert the string (with the Hex data) in number?

    Hello

    I use TestStand 3.5 to automate a few test cases associated with boot loader.

    The requirement is that I need to read the value in some places for specific address. The values of these addresses are stored in a hexadecimal format.

    We have a step customized in TestStand through which we can read these values by address, but she returns as the type "String".

    For example, the value to 0 x 0000008 is 000001 B 2, and he returned in Locals.Value_Read as "000001 B 2" in the string.

    Is it possible, I can convert the string "000001 B 2" to a number?

    I tried to use the function-> val (locals. Value_Read), but it is return 0 as TestStand figures that the input string is not representing the valid number.

    Please help me with this.

    Thank you and best regards,

    Niraj.

    Try: Val ("0 x" + Locals.Value_Read)

  • How to convert an array of string elements to a cluster with elements named different data types?

    I'm looking for more help with the conversion of an array of elements of the chain in a cluster containing elements named different data types.

    I am importing data from an Excel worksheet.  He is coming in LabVIEW as separate (channels) 3 tables: 1) Variable name, (2) three possibilities Int, double, String) data type and the value 3), with the clues in each table corresponding to a separate variable (I have about 180 variables to import).  My ultimate goal is to convert the string array of 'Value' in a cluster.  But I want the correct data type in the cluster and I also the elements of the cluster name to match with the string 'Variable name' table so that I can use the Unbundle based on the name in my main VI.

    Please see attachment a Subvi for more details.  I did the size of the new items of tables 5 for simplicity.   I realize that labels property cannot be changed during execution and I don't think I need to do.  I just want to use the production cluster (mainly the unbundle by name) to help design my main VI.  I will need to 'read' and 'write for' the cluster during execution, but I won't need to change the names of the items.

    I was also wondering if there is a better way to import data from Excel?  Is it possible to import directly into a cluster immediately rather than put everything as strings?  I have attached a Subvi showing how I currently bring in data (found on the forum somewhere).  It comes as table 2D, which I divided into 3 separate tables that I mention above.

    I am open to any suggestion.  Thank you very much.

    -Mike

    Instead of trying to create a cluster, I think I would use only variant attributes.
