How can I limit a double value to two decimal place?

How can I limit a double value to two decimal place?
Java keeps on adding zero's to a simple double subtraction:
1497 - 179.64 = 1317.3600000000001The answer must have been simply: 1317.36

If the trouble is with output ...
If the trouble is with value accuracy ...The trouble is with OPs understanding of and/or expectations of IEEE 754 floating point numbers. o_O
[And it's probably a view (output) issue.]
how can i actually use numberformat to cut those
unwanted decimal places?Read the API - Puce already provided the link.

How can I format the double value?

Hi,
I am trying to format the double variable as like,
double var = 1234.56789
but i want that variable as like var = 1234.56
How can i do that in java?
Please help me.
From
Parshuram Walunjkar

Try something like the following, assume the variable 'd' underneath is your double value that you want to format.
double d = 4.45678;
NumberFormat nf = NumberFormat.getNumberInstance();
nf.setMaximumFractionDigits(5);
nf.setMinimumFractionDigits(5);
String number = nf.format(d);
Then use the string "number" for printing out.

How can I stabilize the DAQ output to four decimal places

I have a daq 6009. I sent a optical signal. DAQ provides a output which varies in 3rd decimal place. I done averaging all using a program which I'am attaching with this. So can you please help me in this regard

You need to find a DAQ with a lower Absolute Accuracy.
Also, looking at the spec, you can get a better accuracy with a Differential measurement than you can with a RSE. Apparently the RSE only works in the +-10V range. By changing to a differential, you can get down to a +-1V range. That will help your resolution a little bit. Just wire the ground to the - terminals on the DAQ.
Another issue could be noise in the system.

You can use NumberFormat class.

Double value truncated to two decimal places without rounding the value.

I want to truncate double value to two decimal places without doing the rounding of the value.
Is there any method which can directly do the truncation.

There's many ways to achieve this such as using
BigDecimal's setScale method or type-casting. This is
the way I like to do it:double d = -5.239;
d = d > 0 ? Math.floor(d * 100) / 100.0 : Math.ceil(d
* 100) / 100.0;
Your division by 100 may cause an rounding error, because there are numbers which no finite binary representation. That's splitting hairs! I know ;-)

How can I convert a double to string

Hello,
how can I convert a double value to a string value?
Werner

an other way: ;)
double yourDouble;
int intTmp;
yourDouble = yourDouble * 100;
yourDouble = yourDouble + 0.5;
intTmp = yourDouble.intValue();
yourDouble = intTmp;
yourDouble = yourDouble / 100;you can write it some shorter...
double yourDouble;
int intTmp;
yourDouble = yourDouble * 100 + 0.5;
yourDouble = yourDouble.intValue() / 100;*100 moves the comma about two steps to the left.
+ 0.5 enables rounding!
if your value is x.5 or larger you get x+1.?
if its smaller than x.5 you get x.?
by parsing the double value to an int the ? is cut.
/100 moves the comma two steps back
you get a double value with 2 decimals which is rounded.
just my coins :)
happy progging,
Thof

How Can I Get A Dollar Value to Display Correctly?

How do I get the following to display the ($) sign in front of the value and two decimal places past the decimal point?
Note that I have set the Text Field Properties>Format: Select format category: Number
Separator Style: 2
Currency Symbol: Dollar($)
[this.getField("Minimum-Redemption-Amount").value has a value of 25000]
app.alert("The dollar amount is " + this.getField("Minimum-Redemption-Amount").value);
displays---> The dollar amount is 25000

var mra = this.getField("Minimum-Redemption-Amount").value;
app.alert("The dollar amount is " + util.printf ("%.2f $",mra));
displays---> The dollar amount is 25000.00 $
-OR-
app.alert("The dollar amount is " + util.printf ("$ %.2f",mra));
displays---> The dollar amount is $ 25000.00

HT2729 I have limited space on my new ipad. How can I limit the number of songs from my itunes on my imac from going to my ipad when I connect the two?

I have limited space on my new ipad. How can I limit the number of songs from my itunes on my imac from going to my ipad when I connect the two?

you can do this by keeping the external hard drive connected and doing the following
-hold shift key down on computer while opening iTunes and a prompt will appear to choose a library
-select choose library, iTunes should bring up your explorer windows where you can search for the external HD
-after you find the external HD find the iTunes folder you just copied to it
-after opening the iTunes folder look for the file that says iTunes library.itl or if you can't see that extenstion just look for a document looking thing in the iTunes folder that shows up as a database file
-double click the database file and boom iTunes should load your library without having to copy it to the computer
PS: do make sure that if you are going to do it this way, make sure that the external HD is connected at all times, because if you don't then you will get exclamation marks next to your iTunes songs
double PS: if you are unsure how to find out if the iTunes library file is a database file just right click it and choose properties and under the type it should say database file
hope this helps:)

How can i get the all values from the Property file to Hashtable?

how can i get the all values from the Property file to Hashtable?
ok,consider my property file name is pro.PROPERTIES
and it contain
8326=sun developer
4306=sun java developer
3943=java developer
how can i get the all keys & values from the pro.PROPERTIES to hashtable
plz help guys..............

The Properties class is already a subclass of Hashtable. So if you have a Properties object, you already have a Hashtable. So all you need to do is the first part of that:Properties props = new Properties();
InputStream is = new FileInputStream("tivoli.properties");
props.load(is);
