The rounding value

How can I round the double value of a not given numbers fraction, Say for example: my double is 10.222222222 for this issue, I want only 10.22 and 10.899999 for that 10.90

How can I do this task?

I wrote getDoubleValue (double) method that rounds the fractional pats

public static double getDoubleValue (double value) {}
Dim str As String = String.valueOf (value);
int index = str.indexOf ('.) ', 0) + 1 ;
String integer = str.substring (0, index-1);
Decimals of string = str.substring (index);
If (decimal.length)< 4)="">
Returns the value;
}
isPre boolean = true;
int i;
for (I = decimal.length () - 1; i > 3; i-) {}
Val As Char = decimal.charAt (i);
If (val > = '5' & val)<= '9')="">
isPre = true;
} else {}
If (isPre & val == '4') {}
isPre = true;
} else {}
isPre = false;
}
}
}
decimal = decimal.substring (0, i);
If {(isPre)
int val is (Integer.parseInt (decimal) + 1);.
{if(Val>=1000)}
Integer = String.valueOf (Integer.parseInt (Integer) + 1);
decimal = '0 '.
} else {}
decimal = String.valueOf (Integer.parseInt (decimal) + 1);
}
           
}
return Double.parseDouble (integer + "." + comma);
}

  • return only the decimal value

    What function can I use to return only the decimal value of a formula

    (97 * 2.2) / 14 value returns 15.24

    I only want to use le.24

    Salvation is

    Use the formula - INT (formula)

    In the special case above:

    =(97*2.2)/14 - INT ((97*2.2)/14)

    You see two places to the right of the decimal separator in reason to be rounded off to the value real, in the shape of the cell to only show as two decimal places, either by setting the width of the cell close enough to force the rounding of the displayed value.

    Note that if the result is rounded (using the ROUND function) the actual value of the cell will be the rounded value. For the other two cases, the value displayed indicates only two decimal places, but the real value in the cell (and the additional calculations used by referring to this cell) is 0.242857142857144, which could lead to surprises in the results of the calculations downstream.

  • Insert row into table 2D retaining the previous values

    Amendment of data entered in a 2D array and also displayed a table. When the time rolls 3 columns of data are held and then created line. Problem is the line moves downwards, but the previous data is not stored. I tried using shift register, but that only auto markings lines table to fill as the iteration of the loop. Looks like a basic really simple problem but going round in circles on this one there...

    In this case, the function 'Replace table subset' is what is needed to replace the last values in line with the current values of the user interface.

    On the evolution of the time, an addition occurs.

  • What is the unit for measuring the roundness in CircularEdgeReport_struct?

    Hi-

    I thought roundess %, but looks like I have greater than 100 for this value.  Can someone tell me what the unit is roundess value in this structure?

    Thanks in advance-

    Blue

    Hi blue,

    According to this, it looks like the roundness is maybe referring to the least square error of the circle that is adjusted to the set of points.

  • Search for the nearest value table

    IM wondering if its possible to find a 1 d table worth, if it is not found, then find the nearest match. IM using the 'double' data type and I need at least an accuracy of 4 decimal point in the research.

    For now, im rounding decimal values to the nearest integers from you, but it is not effective at all. Im getting a lot of unwanted split in the plot. I need to be able to search for the decimal points. I found this function "About Equals.VI" starting from a previous thread. Even that uses the concept of the rounding.

    I enclose 3 screws "0.8 & 0.4.VI" are that I created, rounding decimals nearest digit.

    The "approximately equal" is the one I found online.

    The 3rd is I try to mess with what I can find as close a match.

    Y at - it a trick to work around this problem?

    Thank you

    This VI uses the first type of step 3 in your data.  Since you said that you can get the data, you can drop the in VI.

    At the end where I calculate the slope, you can use a linear adjustment if you have full or professional LabVIEW.

  • Rounded values of AE setValueAtTime script?

    Hi guys,.

    I'm just getting started with extendScript, and I ran a question.

    I'm trying to set a keyframe to a value (admittedly) large, After Effects sets a value that is different from the value that I. It seems to be snapping more rounded and incoherently.

    For example, the values I put in the script, and what After Effects is layer on keyframe

    1248304.6823 1248304.625

    -4720535.9958 - 4720536

    4092748.7335 4092748.75

    You can see it seems to be 'registration' values in de.025 increments, but it does so inconsistently with a value to another. Is there a setting that I can put in the script to force it to use the actual value I want?

    What is strange is that if I copy and paste these values into After Effects directly on keyframes, it rounds up to 3 significant figures, as I expect.

    Is it all just because my numbers are too big? And if so, why the After Effects has no problem with the values?

    Ideas or ideas would be very appreciated!

    for (var i = 1; i & lt; = app.project.numItems; i ++) {}

    var textName = comp.layers.addText ('test');

    textName.threeDLayer = true;

    textName.position.setValueAtTime (0, [1248304.6823,-4720535.9958, 4092748.7335]);

    }

    }

    Zewt! You are a hero!

    I took an approach changed to your idea:

    I put int and decimal fractions of value as the positions on two null objects.

    Then I used an expression on the camera.position to combine these two values.

    Finally, I used this script I linked to convert expressions camera.position in keyframes and remove NULL values.

    That way I would create two distinct null objects and do not create two for each axis (x, y, z).

    In addition, the control slider has a limit of 1 000 000-1 000 000 which was not enough for what I had.

  • move on to the Round Robin

    Hello people,

    I'm a bit confused. I have my now see that they are defined as VMW_SATP_ALUA_CX and storage (EMC CX) defined on the failover mode 4, host rebooted. I think that now, I can go in each data store and change the path of 'Round Robin (VMware)' selection. I do a lot of MSCS and noticed that the Round Robin is not supported with SAM. I found the underside of VMware. He says Round Robin PSP is not supported for the LUNS mapped by RDM, but then there is a "note" that says with NMP, clustering is not supported when the value of the Round Robin. It's my confusion is not the note by repeating exactly what he says just on top of it, or I'm not getting something? Also, I'm running 5.0, are there other changes that I have to do to make this work?

    Strategy selection of the path (PSP)

    Round Robin PSP is not supported for the LUNS mapped by RDM used with shared cluster storage. If you decide to use PSP Round Robin with your storage array, or if the version of vSphere to uses the default values for PSP Round Robin for the table in use, you can change the PSP claiming the RDM LUN above other PSP. For more information, see editing a unit number logic to use another path selection policy (PSP) (1036189).

    Note: with native multipathing (NMP), clustering not is not supported when the strategy of path is set to Round Robin. For more information, see vSphere MSCS Setup Limitations in the configuration for Failover Clustering and Microsoft Cluster Service Guide for ESXi/ESX 4.x or 5.x ESXi.

    Any help would be great. This confuses me

    -MN

    For data warehouses, use RR and ALUA (4 failover mode) mode.

    For members of the MSCS (RDM) cluster, you will need to use fixed.

    Using "fmDay" avoids filling and the pivot works according to the needs:

  • You can change the default values for shape layers?

    I know that I can copy and paste these properties also but I wonder on changing the default settings - perhaps in a preferences file? Thank you

    No, there is no way to change the default values. If you have a set of properties that you always want to use, you can save them as a preset.

  • Shoot/Get/the data value of the window for user input

    I'm trying to do something that should be simple enough for a programmer, but unfortunately, unfortunately to be a designer, I'm having a devil of a time with it.  After spending hours searching and trying different things, I thought to post the problem.  I have the feeling that I'm not the first creator of evil with it.

    I'm trying to extract a window input data and to transmit it to a variable.  In the script, I do a few purge(), and I don't know if that clears the values of input from the user during the script, but it's thinking ahead...

    I need the values to:

    Layer.translate (X, Y) / / if I'm wrong, it must be not - string

    bitsaveoptions. Method = ChanelScreen; in menu drop-down

    bitsaveoptions.angle = KAngle / / if I am mistaken, this must not be one - integer

    bitsaveoptions. Frequency = ChanelFrequency; If I am mistaken, this must not be one - integer

    bitsaveoptions. Resolution = ChanelResolution; If I am mistaken, this must not be one - integer

    bitsaveoptions. Shape = BitmapHalfToneType.ROUND; in menu drop-down

    I know that there are different ways to retrieve data from a window how .value, and perhaps others, but I can't seem to extract the data from user input

    Any advice would be greatly appreciated.

  • How to make the absolute value of the Member

    Hello
    I have an account which must contain an absolute value only 1 or 2 or 3 but not of decimal numbers
    is there a way in which we can limit the Member to only contain a value.
    If I disable the decimal details form so it doesn't not display the decimal value, but I can still enter a decimal value.

    Hello
    If what you mean is to allow users to enter only from the list of pre-defined numbers, you can use Active lists.
    Or if you want to restrict the entries as integers only, you can apply via customization in validatedata.js. Alternatively, you can write a business rule in order to convert the entire entry. The script function calc, you need to use is @ROUND.

    See you soon,.

  • How to highlight the minimum value in a column?

    I need to highlight the lowest value in each column in my spreadsheet. I try to use the conditional nail, but I can't find a function to work as I need.

    One way would be to calculate the minutes in a cell of a footer row, select the cells in the body of the column and apply conditional highlighting like this:

    You must click on the chip address first, and then select the comparison cell, A8 here, then be sure to keep the row and column.

    The A8 from the example formula is = MIN (A).

    The result is a bold 2 (not shown in the screenshots).

  • Firefox is the default value. Whenever I click on a selection of browser to URL is displayed.

    I've defined and confirmed that Firefox is my default browser. I uninstalled Firefox, restarted, set Edge as default, rebooted, reinstalled Firefox using the option 'Make Firefox the default browser' and rebooted. No matter what the settings are made and Firefox is default, when I click on a URL link, I get a dialog box "How do you want to open this file", Firefox is highlighted, I click on the check box always 'use this app' and click OK. Firefox opens and displays the page. Thereafter, whenever I click on a URL link I get the pop up and choose Firefox. It doesn't matter if a Firefox session is active or Firefox is closed. What I am doing wrong?

    This was a problem when you try to set one browser by default other than IE (now Edge) on Windows. Firefox has had the most problems over the years, trying to get himself defined as default browser. I can't tell if Chrome has had the same problem either. But I feel that they have had a hard time with her also.

    In the interest to see what works and what does not work, could you not install the Chrome browser and by setting the default value to see if it does indeed remain the browser by default when you click on any url? Please test the links of the opening a few times before you say that it works without problem.

    I'll be tracking of any workaround to set Firefox as the default browser in the meantime. But, be aware that Microsoft is the enemy here. As they do on board the default browser at any price.
