Take the minimum value for table data

• What is the minimum value for the data type double?

  ... a more academic question: what is the minimum value of the data type double? I thought 'double', it is the 8-byte IEEE standard and what I remember, it's + - 1.7E + - 308.  The more different number of 0 should be 1.797E - 308.

  This is why I was a little surprised when I looked at the data output of my calculation of CVI, where I found the numbers with exponents of E-319 or E-324 as the smallest value...

  But I'm sure there's an explanation :-)

  Thank you for sharing with me,

  Wolfgang

  The largest number is indeed the order of + 1.7E + 308; There are a smaller number of - 1.7E + 308. Note that this is in fact the most negative number, which is the smallest by some reckoning. For the small beach of the Exhibitor, things get a little more complicated. 1E-308 can be represented with complete accuracy and resolution, but if you're willing to lose a few bits of precision, you can go down even further. For example:

  Double x, y, z:

  x = 1E-300;

  y = 1E7;

  z = x / y;               Give 1.000000000000000E - 307

  y = 1E8;

  z = x / y;               Give 9.999999999999999E - 309

  y = 1E18;

  z = x / y;               Give 9.999987484955998E - 319

  y = 1E23;

  z = x / y;               Give 9.881312916824931E - 324

  So, as you can see, values less than 1E-308 are possible, but they become increasingly more inaccurate and should not be relied upon.

• How to set the minimum value for the division based on the metric of Super?

  I want to create the Super metrics include:

  (Data reading KB store / writing KB) * 100

  To get an understanding of the relationship between reads and writes.   However, this equation will always climb 0 if a number is 0.

  Is there a way to say "if read = 0 then read = 1 ' so that the equation will not evaluate to 0?

  Thank you

  -MattG

  There is no 'if' statement... but thought that you can add a (metric + 0.0001) which should not be 0

• Select the lines with the maximum value for a date where another column is different from 0

  Hello

  I need to write a query on a table (called DEPRECIATION) that returns only the rows whose date maximum (PERENDDAT_0 column) for a specific record (identified by AASREF_0), and where the other column in the table called DPRBAS_0 is different from 0.

  If DPRBAS_0 is equal to 0 in all the lines of a specific record, then return the line with date maximum (PERENDDAT_0 column).

  To be clearer, I give the following example:

  Suppose we have the following data in the table of DEPRECIATION:

  AASREF_0	PERENDDAT_0	DPRBAS_0
  I20110010743	31/12/2015	0
  I20110010743	31/12/2014	0
  I20110010743	31/12/2013	0
  I20110010856	12/31/2016	0
  I20110010856	31/12/2015	0
  I20110010856	31/12/2014	332
  I20140012238	12/31/2016	445
  I20140012238	31/12/2015	445
  I20140012238	31/12/2014	0

  The query must return only the following lines:

  AASREF_0	PERENDDAT_0	DPRBAS_0
  I20110010743	31/12/2015	0
  I20110010856	31/12/2014	332
  I20140012238	12/31/2016	445

  Thanks a lot for your help!

• How to get all minimum values for a table of valuable documents?

  Hello

  Aggregate functions reduce the result set with one row per group.
  Almost all of the aggregate functions are homologous analytics that can give the same results without restricting the result set. Since you want the output to contain several lines per group, then the analytic functions are probably better for you.

  Here's one way:

  WITH      got_analytics     AS
  (
       SELECT     name, org, desig, salary, year
       ,     MAX (salary)  OVER ( PARTITION BY  name, org, desig)          AS max_salARY
       ,     ROW_NUMBER () OVER ( PARTITION BY  name, org, desig, salary
                                  ORDER BY        year  DESC
                         )                              AS year_num
       FROM    emp
  )
  SELECT     name, org, desig, salary, year
  FROM     got_analytics
  WHERE     salary          = max_salary
  AND     year_num     > 1

• Filter for table data, the range of data obtained and defined 2D

  I produce data of an ultrasonic sensor at 1 K Hz, and there is a lot of data (data points range of 0 to 10). However, in some cases when I know that the data should be about 7 (for example) I get outliers (about 9 and 10). Is it possible to define a filter for data in the defined range.

  I averaged the data to get an average value, and outliers are distorting. In the worst case, my outliers are 30 to 40% of the data generated. I created a filter to sort the data and, taken from the lowest value. I stop the loop when data reaches a value greater then 9. But this seems to take a long time (because the loop checks for each data point and there are 1000s of them).

  Is there a better way to filter data and define a predefined table range to collect?

  I enclose my filter.vi... and a set of samples of my previous data. The ranges of data of 10-8 and would like to have the range 7.5 to 8.5 to consider. The sensor records tension here and the problem can be solved by installing a different type of sensor, but if a filter in LabView can due it, the sensor that we use now is absolute.

  I am in kind of emergency, my design in unfinished because of this problem, if someone can find some time to share some suggestions, I will be grateful.

  Thanks in advance.

  See attachment.  I have incorporated the data you've posted in the vi.  It doesn't seem like any data were less than 8.7 or so, so I modified the scope so it would be a few points on average.  Some games were completely out of reach while the average came back like NaN (not a number) due to a division by zero.

• Find the minimum value of the table in time...

  Firstly that it is not "find the min value in the table.

  It is:

  I have a table that changes its values at each iteration, and I want to compare the new values with previous values and make a new array with the minimum values...

  In C++, it would be like this:

  int main() {}

  int array [8];

  int min [8];

  int i;

  for (i = 0; i<>

  min [i] = 1000000; Initialize minimum table with a high value

  }

  {while (1)}

  Array = update_array ();

  for (i = 0; i<>

  If (array [i]<>

  min [i] = array [i];

  }

  }

  do things...

  }

  return 0;

  }

  IM new to labview and it always confuses me a lot...

  Thanks in advance.

• The default value for a property with data of type boolean

  Hi all

  Is it a system preference setting, where the default value for a property with data of type boolean can be a Virgin? I want to keep the value by default in a vacuum, but every time I save the property even after empty selection, the default value changes to FALSE.

  

  In this case Boolean doesn't help you, you mayneed to create a chain of ownership and have true/false / "" as your list of values

• PL/SQL loop to find the minimum value

  I want to find the minimum value from a table using the pl/sql loop

  If rec.sal > fmin then
  fmin: = rec.sal;
  on the other
  FMAX: = rec.sal;
  fmin: = fmax.
  end if;
  end loop;
  dbms_output.put_line (Fmax);
  end;
  /

  I want to output 2 on top of code.

  Thanks in advance

  Why PL/SQL? SELECT MIN (SAL) OF TEST will be more rapid and much less coding. In any case:

  declare

  number of v_min_sal;

  Start

  for v_rec in a loop (select sal from emp)

  If nvl (v_min_sal, v_rec.sal + 1) > v_rec.sal

  then

  v_min_sal: = v_rec.sal;

  end if;

  end loop;

  dbms_output.put_line (' lowest salaray is "' |") v_min_sal | '"');

  end;

  /

  The lowest Salaray is "800".

• SQL-MIN() don't not returns the minimum value

  This is my code;

  $SQLx = "SELECT MIN (price_from) AS minimumprice FROM AN_pricetable WHERE accomm_id =". "." $db_field ["accomm_id"];

  $resultx = mysql_query ($SQLx);

  $pricefrom = mysql_result ($resultx, $i, 'minimumprice');

  If ($pricefrom == 0) {}

  $pricefrom = 'TBC' ;}

  But for some reason, it is not the minimum value "price_from". For example, several rows in the table have the same "accomm_id", and their values in the field 'price_from' are: 8, 12, 50-7, but the SQL code returns the MIN 12. What I'm doing wrong here?

  Thank you

  What is the data type of price_from?  If it is a type of string (char), then 12 would be the lowest value.

• Best way to set the default values for the form elements

  Hello
  
  I have a form with a lot of defaults that is mentioned below...
  

    Field                      value  
    created by             :APPL_USER
    creation_date         SYSDATE
    last_updated_by     :APPL_USER
    last_update_date    SYSDATE

  I am currently using calculation-> after presents... then when we create/update a record... these computaion takes place and the default value for the inserted values get... THIS WORKS PERFECTLY WELL.
  
  I want to know... If this approach is fine OR we can have a better approach to achieve...?
  
  Thank you
  Deepak

  Hello

  I think it's good if it fits your need.

  But why you have these fields in the form?
  created by: APPL_USER
  CREATION_DATE SYSDATE
  last_updated_by: APPL_USER
  last_update_date SYSDATE

  The user can enter the ones?
  I thought that those who are to audit and I would fill those drop with trigger in the database.
  So that you get the same "correct" values if you need to manipulate the data with example of sql client
