How to see decimal part of float value?

How to see only value of decimal part of float value?
For example, if I have 1.455, i need only to see .455 part.

Read the floating point value.
Convert that into a string.
Use the String's substring and indexOf method to find
the "." and then cut from there, to the end of the
string.<sarcasm>
Really? I'm sure pbrockway already said that but i must be mistaken.

How to see a null or empty value in JFormattedTextField

Hello, I am having a problem. I'm trying to use a JFormattedTextField, and I keep getting errors.
I know what is causing the error, but I don't know how to fix it.
Here is my code:
String cf = countFTX.getText();
if(cf.equals(" ")) {
i = Integer.valueOf(countJTX.getText());
}else{ i = Integer.valueOf(countFTX.getText()); }what happens is I get an error when it goes to change it into an int. Because it see's it as being (" ") and not (" ") or even ("") so it doesn't fit into my if statement. And returns it being false, then tries to turn it into an int, and blows up there.
Now how can I fix my if statement to be able to see if nothing was entered, and if so then use the countJTX and not the countFTX?
countJTX is a regular JTextField, and countFTX is a JFormattedTextField.
the JTX is filled automaticaly with an int, and if there needs to be a change, the user puts it into the FTX. (so you understand the logic behind it)
any ideas? or should i just revert to not using the FTX?

you need to know the differenct between NULL and "" (empty) of a string. Also both of these values cann't converted to in integer so you can not call Integer.valueOf(cf). I don't understand why you need to do that. Instead:
    String cf = countFTX.getText();
    if(cf == null || cf.length() == 0)) {
        i = ?; //something you want i to be when cf is null or empty but not call Integer.valueOf(countJTX.getText());
    }else{
        i = Integer.valueOf(cf);
    }Also, you may need to add try/catch exceptions.

Busiiness Objects dropping decimal part of imported value

I am using a csv file as the basis for several reports. The values being imported have integer only and decimal values. Business Objects appears to import only the integer value of every record even if the record contains a decimal value. Is this a know response, problem, in Business Objects and is there a work around or is there a configuration value that needs to be changed?

Which version of BOBJ do you use? Did you install any additional language packages?

How to fix the decimal part(round) i.e. fix the size of float.

how to fix the decimal part(round) i.e. fix the size of float.

You can use BigDecimal to round of your number.
float f = 5.678f;
f = new BigDecimal(f).setScale(2, BigDecimal.ROUND_HALF_UP).floatValue();If you just want to display the float with a certain number of decimals, you can use java.text.DecimalFormat
DecimalFormat df = new DecumalFormat("0.00"); // two decimals
float f = 5.678f;
System.out.println(df.format(f)); // should show up as 5.68

How to extract an integer or a float value from a String of characters

Hi i have a problem getting to a float value within a string of characters..
for instance the string is
"numberItem xxxxxxxxx 700.0" (each x is a space..the forum wouldnt let me put normal spaces for some reason)
how do i store 700.0 in a float variable
remember the string is obtained from an inputfile
so far i got the program to store the inputfile data line by line in a String array..i tried tokenizing the string to get to the the float value but since i have mulitple spaces within my string, the token method only gets "numberItem" from the above String
This is all i have so far:
String c;
String Array[] =new String[g]; (i used a while loop to obtain g(the nubmer of lines in the file))
while((c=(cr.readLine()))!=null)
Array[coun]=c;
it would be reallllllllllllllllllllllllllllllllllllllly easy if there was a predefined method to extract numeric values from a string in java..

Not true.
Anyway why not use string split, split on spaces and grab the last element (which by the format you posted would be your 700.0)
Then there is the Float.parseFloat method.
It is easy.
And another thing why not use a List of Strings if you want to store each line? (And why did you post that code which doesn't really have anything to do with your problem?) Also in future please use the code formatting tags when posting code. Select the code you are posting in the message box and click the CODE button.

How can i write the floats value in Unitronics vision230 plc using modbus Ethernet

How can i write the Float value in unitronics Vision230 PLC usinsg modbus ethernet (MB Ethernet Master Query.vi) I read and write the 32 bit register, for e.g i want to write the 23.45 value on 2nd add. of MF. And MF register is 32 bit register. I read and write the 32 bit register.
Narendra.
Solved!
Go to Solution.

Thanks Amit for your solution but i can not use the string to write the value because MB Ethernet master Query.vi only accepet the integer value its not take string values or any other i.e floats values etc.....otherwise i have no problem to write or read the 32 bit register values , only problem is that the MB Ethernet master Query.vi only accept the integer value there4 how can write the float value.

How can i do to see the master and text values of the Key figure 0UNIT

Hi gurus,
How can i do to see the master and text values of the Key figure 0UNIT, please step by step, i m in the key figure 0UNIT but i want to see if the UNIT for example BX = BOX, something like this is that i want to check, thanks!

If you look at the unit tables, you will see the values and texts. It's in SPRO, not in RSA1. My access is limited on my system here, but the documentation says to go to t-code CUNI. I believe in that tcode you can look at all of the unit equivalencies and what each unit's text is ..... like an ea means each; KG = Kilogram; etc...
I am on an 3.x system, so in SPRO I go to BW CIG=>General Settings=>Check units of measurement.

How to see the peak values in a chart?

I have the following situation: I am applying the FFt to an acceleration signal. In the FFT-peak graph I see different peak frequencies. However I would like to know how much are those peak values and either display them in the chart on top of the peaks or extract them in numerical indicators. Is any of these solutions possible in LabView?
I guess the question stands for any kind of graph or chart where you want to extract and see only certain or peak values. Any suggestions?
Thank you.
Radu

OK. Attached is a VI which allows you to move cursors 0 and 1 to select any section of a graph, and then click a button to get the maximum of that particular section. It also places the third cursor (red) at the location of the maximum it finds. It is all done using property nodes of the graphs.
This VI is based on an exercise of the LabVIEW Basics II course, which I took a long time ago, but the manual of which is still very useful.
Hope this helps.

How to keep 2 decimal places for double value

Hi,
I need rounding function, which should round a double number till 2 digits, if there is no decimal part it should append 2 zero's in decimal places.
eg. 100 --- > 100.00
200.234 --> 200.23.
I tried with Number class. but it is returning string, from that string if I try to convert to double value, it is rounding off one digit.
Can any one help on this problem.
Thanks,
Suman.ch

I am using xmlBeans using that I need to write this
rounded value into a xml file, for that I need only
double value with 2 decimal places.You can probably write the value as a String instead of a double somehow, so you can use the DecimalFormat class.
You could try their mailing-lists for users/developers:

your_col - trunc(your_col)Do you have negative numbers?
For negative values what do you want to display?
If just the decimal part, you could use ABS(col) - trunc(ABS(col))
