Re: Issue regarding NumberFormat

[Ignacio Baca Moreno-Torres]

The dot (.) inside the pattern is a token that represent the 'decimal 
separator', and the decimal separator for fr is a comma (,).

Issue regarding NumberFormat

[Gaurav Mourya]

Hi All,

I am using GWT 2.5.1 and I have an issue regarding “NumberFormat” supports 
for multiple language.

Please refer the following below URL : -  
http://samples.gwtproject.org/samples/Showcase/Showcase.html?locale=en_GB#!CwNumberFormat

As per required pattern I’ll be not getting value.

For example at top right side you will get drop down, which are having 
multiple languages.  

Select “British English” (en) and you may see the below. It’s formatting 
the value in defined pattern.

But if you select the “France” (fr) locale. Then it won’t displaying 
properly formatted value, the dot (.) is replaced with comma (,).
 Please let me know if you have any solution.



Thanks & Regards,
Gaurav Mourya

new DecimalFormat("#,###.00"),
new DecimalFormat("#,##0.00")
};
double[] vals = { 3.57, 0.98, 0.6 };
for (DecimalFormat nf : nfs)
  for (double v : vals)
System.out.println(nf.format(v));

==>

3,57
0,98
0,6
3,57
,98
,60
3,57
0,98
0,60

(French locale!)
I am not sure how to interpret that when reading the JavaDoc...

NumberFormat and Internationalization Messages

[Thad]

I'm am unable to get com.google.gwt.i18n.client.Messages for format a float 
in production.

My DefaultMessage looks like "{0,float,#.0}\"". In DevMode, my number has 
one digit after the decimal, e.g., 8.8" or 11.6"

In production--now Javascript vs Java--the number has *many* digits after 
the decimal, e.g., 8.80190734863" or 11.60381469726"
This is true in IE and Chrome (I've not tested Firefox and Safari).

Am I wrong thinking that this formatting should work like 
java.text.NumberFormat?

Why would you ever want to do that? Now you users don't know if you are 
displaying 234 or 1234 of 1000234. Your trouble might be coming from this 
unusual formatting you are attempting. Most number formatting functions 
won't do this because it does not make sense. They focus on truncation and 
rounding of the decimals which simply reduce the LSB's, not the MSB's.

If you must do this, just write your own function to truncate the higher 
magnitude values.


Sincerely,
Joseph

How to use NumberFormat to set maximum number of integer digit

[Mao Qin]

Hi everyone, 

There is one topic about how-to use NumberFormat to set minimum number of 
integer digit.
But now I come across one problem, I only wanna keep the decimal format 
looking like "000.00", three integer and two number after decimal point. 
that means format a 1234.567 will get 234.58.
how to use NumberFormat to set maximum number of integer digit. Since 
java.text.NumberFormat is very convenient to do this job.
By contrast, com.google.gwt.client.i18n.NumberFormat is seemed as it could 
not perform this function.
should I need to write a function to implement it or maybe use a special 
pattern?
Do someone have any suggestions?
Thanks!

Best Regards!

Re: NumberFormat currency pattern issues (wrong positiveSuffix and possible encoding issues)

[Tiago]

Well, "$10" or "10 USD" should clearly be invalid strings for an euro
locale.
I wouldn't mind "10 EUR" being invalid for the default format too
since using currency codes is quite specific. Actually, all these
could be configurable parameters (requiring, ignoring or refusing
currency symbols and/or currency codes). What I don't find correct is
to always require a " €".. the user can't even type a  ...

Not being able to use NumberFormat to parse currency values would be a
pity. I would expect to be able to use the same format both ways
(formatting and parsing). And well, if this choice is made "by
design", shouldn't it be documented? The exception "X does not have
either positive or negative affixes" doesn't have anything to do with
the actual issue. " €" is not a "positiveSuffix".

Thanks

If you want to parse a number, don't use a currency format.

Thank you Thomas for the clarification.

Do you agree though that there's a bug on NumberFormat? It should not
require " €" to be in the end of a string it parses, although it
may add it to the end of a string it formats. Right?

NumberFormat currency pattern issues (wrong positiveSuffix and possible encoding issues)

[Tiago Rinck Caveden]

Hello,

I'm having some weird issues with NumberFormat. I'm using it with the
currency pattern, which for my locale is the euro.

The first problem I've notice is that the parser is treating the string "
€" as a "positiveSuffix". And if such string is not at the end of the
string being parsed, the error "X does not have either positive or negative
affixes" is raised. And well, it's normal that such suffix is not there,
people won't manually type a space plus the euro symbol. It's ok if such
string is added by the format method but it should not be required by the
parser.

I guess that's pretty much a bug for NumberFormat, right?

And well, that's not all. After trying to work around this by manually
adding the " €" to the end of my numbers, it still raised the same
exception. So I decide to debug it, and I saw that, in spite of the correct
string being there, the endsWith method was returning false. I just
couldn't understand, until I decide to add a watch expression requesting
the getBytes() of each string. And what was my surprise when I saw that the
blank space character had different bytes in each string being compared! In
the "positiveSuffix" variable of NumberFormat, the space character was
represented by two bytes, while in my input string, it was only the byte
32. Actually, it seems my input string was using an 8 bit encoding, since
only the euro symbol used more than one byte.

These are the strings and their bytes:
The input:  "10 €"  =>  [49, 48, 32, -30, -126, -84]
The positiveSuffix:  " €"  =>  [-62, -96, -30, -126, -84]

As you see, it seems blank space in the input is 32 while in the
positiveSuffix it is [-62, -96].

I'm guessing javascript doesn't give the same guarantee that Java does,
that is, that every in memory string uses the same encoding. But, if that's
the case, shouldn't GWT try to assure always the same encoding is being
used? Because, otherwise, how should we do? I know that we can set encoding
for Writers and Readers in Java but for in memory strings, how can we make
sure we're always using the same encoding?

Thank you,

NumberFormat format with all available decimal digits

[Raziel]

Hi, I would like to be able to call the NumberFormat format method
with a Double and get in the string all the digits available in the
Double value.

It seems to me that you have to forcefully specify in the patter one
digit per decimal you want to display (i.e. "#.#" for 5 decimal
digits, "#.##" for 2, "#.###" for 7, etc.), or otherwise the
format method would round it up.

Is there any way or pattern where I can specify the formatter to "show
all available decimals in the passed double value"? Something like
"#.#*"

Any help will be greatly appreciated.

Thanks

Aw: Re: NumberFormat and German Locale

[Jens]

NumberFormat.getDecimalFormat() just gives you a formatter using a default 
format string. If you want to use your own formatting string you have to use 
NumberFormat.getFormat(). In your case you have to use 
NumberFormat.getFormat("#,##0.0##"). The symbols "," and "." are special 
symbols used by the NumberFormat class for grouping and as decimal 
separator. You always have to use these symbols like they are defined in the 
JavaDoc for NumberFormat regardless of the target locale you want to use. 
The target locale is then responsible for changing "," and "." into the 
correct localized versions. For de_DE that would be "." for grouping 
(instead of the defined ",") and "," as decimal separator (instead of the 
defined ".").

ok, I think I understand what you are saying. But it's still a mystery
to me, how to tell the localized NumberFormat, e.g.
NumberFormat.getDecimalFormat(), to use ths user supplied pattern, eg
setting a certain precision, leading/trailing zeros, and such like.

Re: NumberFormat and German Locale

[Thomas Broyer]

You're confusing the syntax of the pattern you give to NumberFormat for 
parsing, and then the use of that NumberFormat within the context of a 
locale.
What you *give* to NumberFormat is locale-insensitive: #,##0.0##
When you have that NumberFormat instance, what it does then depends on the 
current locale: when you format 1234.56 in the de_DE locale, you'll see (if 
I'm not mistaken) 1.234,56, in the fr_FR locale it'll be 1 234,56 and in the

Re: NumberFormat and German Locale

[tdk]

Tom, Rob,

thanx for this valuable information. That default is not "default" is
quite interesting, I wasn't aware of that.
But then the question is, how do I change the NumberFormat so that it
uses the set locale, eg de_DE, instead of "default"? I have not been
able to find/understand a way to do that. Maybe you can help me with
that...

The problem I have is that I can't use a fixed locale because my users
can change the language/locale on the fly. With the help of this and
other forums I found the way how to do that by reloading the app with
an "locale=de_DE" appended to the original URL. Not very nice and
elegant but it seems to be the only way. And as I mentioned in my OP
it actually works as far as the messages from GWT are concerned.

But what about NumberFormat (and DateFormat for that matter), how can
I change the default locale?

Re: NumberFormat and German Locale

[Thomas Broyer]

In a pattern, a dot is always the decimal separator and a comma always 
represents the thousands separator. When you render a number using the 
pattern, those separators might appear differently depending on the locale 
(e.g. the decimal separator being a comma and the thousands separator being 
a dot).

As Rob said, the default locale is not the "locale used by default", it's 
the locale called 'default' (Java would call it the 
ROOTlocale,
 and many systems call it 'C'; it is 
*not* 'en' though, even though it looks a lot like it).

Re: NumberFormat and German Locale

[Rob Coops]

Default locale is actually default, not necessarily the local set.

I don't have access to my code at the moment so I'll have to do this from
the top of my head and without actually working code... but I'll give it a
try.

When a new user accesses the app I check the locale, to see what this is set
to, "default" or something else, if it is set to default then I force it to
the locale inferred by the user's IP address, if I have this local available
otherwise I set it to English.
There is such a thing as default in the list of locale's which usually is
_EN as far as I know.

I think what you are seeing is that the "default" locale you are using is
actually default (_EN) thus the number format is most likely set to
#,##0.0## instead of the #.##0,0## you are trying to use. I would suggest
simply telling the number formatter to use the _DE format (or simply the
same as the locale is set for for the user ;-)

Sorry for the lack of code, that the explanation is clear enough without it.

Regards,

Rob

NumberFormat and German Locale

[tdk]

I have severe problems, understanding and using
com.google.gwt.i18n.client.Numberformat, hoping somebody out there can
help and enlighten me.

When I try to get a formatter via NumberFormat.getFormat(pattern) I
get an InvalidPatternException even so my pattern is valid within the
german locale, eg #.##0,0##.
I know that the locale is set correctly and used by my app, because
all the default texts, eg when loading data, show up in german.

The documentation (and posts in various forms) say, that NumberFormat
uses the default locale to get a formatter, with a specific pattern,
which I assume in my case is de_DE, because it is set to this. So what
am I doing wrong, am I missing?

I'm using GWT 2.3

NumberFormat not formatting single-digit numbers

[Kyle]

Hi!

I'm working on an enterprise GWT/GXT application and we've recently
noticed that our currency fields are not correctly formatting single-
digit inputs.

We're using java.math.BigDecimal to represent the internal values, and
using NumberFormat.getFormat("$#,##0.00; ($#,##0.00)") for our format
setting.

What happens is when the user enters a value in a field (which has a
correctly-formatted default value of $0.00) and hits tab to exit the
field, the format only applies to entries that are 10 or larger.  If
they enter a single-digit value, it won't be formatted.  They can work
around this by first entering a number 10 or larger, tabbing out, then
going back and changing it to a single digit value, and tabbing out
again, at which point the formatting correctly applies.

To further complicate matters, this only occurs on the actual server;
the formatter works perfectly fine in local hosted mode.  This occurs
in both IE8 and Firefox 3.

We're running GWT 2.1.1.


Thanks for your time!
/Kyle

fixed-width numbers with NumberFormat

[decitrig]

I know I can pad a number with zeros, is there a way to pad them with
blanks? There are a couple of rules in the EBNF that seem to point
this way:

number  :=  (integer ('.' fraction)?) | sigDigits
sigDigits   :=  '#'* '@''@'* '#'*
padSpec :=  '*' padChar
padChar :=  '\u'..'\uFFFD' - quote

sigDigits, padSpec and padChar don't seem to be referenced anywhere in
the docs, and I've played around with asterixes and at-signs in the
argument for getFormat without any luck.

Re: Currency Symbol in NumberFormat

[Jim Douglas]

Click this link:

http://gwt.google.com/samples/Showcase/Showcase.html#!CwNumberFormat

Look for the ListBox in the top right corner of that page.  Select
"English - India" from that list.

The page changes to:

http://gwt.google.com/samples/Showcase/Showcase.html?locale=en_IN#!CwNumberFormat

Note this addition to the URL, indicating that the locale is now
English - India:

?locale=en_IN

Now select "Currency" from the Pattern list.

It now reports that the formatted currency value is rupees (Rs):

Rs 31,415,926,535.90

I see that this will eventually be changing to a brand new symbol
encoded as U+20B9 in Unicode 6.0:

http://en.wikipedia.org/wiki/Indian_rupee_sign
http://www.fileformat.info/info/unicode/char/20b9/browsertest.htm

For one final test, select "Custom" from the Pattern list, then copy
and paste this text into the text box below that list:

¤ #,##,##0

Change "Value to format" to 42.

It now reports that the formatted value is:

Rs 42

Re: Currency Symbol in NumberFormat

[Jim Douglas]

I think you're getting thrown by a small character encoding error on
that documentation page:

http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/i18n/client/NumberFormat.html

The page will display correctly if you force it to display in UTF-8.
To do that, select something like View->Encoding->Unicode (UTF-8) from
your browser menu.

The pattern character is exactly what you expect it to be.  To see a
live sample, go here and select the Currency pattern from the list:

http://gwt.google.com/samples/Showcase/Showcase.html#!CwNumberFormat

Currency Symbol in NumberFormat

Hi,

I want to use custom number format which may contain currency symbol
for perticular locale. I found that with the
com.google.gwt.i18n.client.NumberFormat class we can achieve this but
the symbol for the currency is ¤ instead of ¤ in java. Note that the

Why does GWT not have a getIntegerInstance() in NumberFormat??

It seems simple enough to implement and it is part of java...

Is it implemented somewhere else?

NumberFormat

[brianw]

hi there,

I've been trying to format decimals numbers in the French style; eg
5 000,00
tried setting a number pattern, nothing worked;
api says "corresponding locale symbol collection" are in
com.google.gwt.i18n.client.constants and there one reads:
 use LocaleInfo.getCurrentLocale().getNumberConstants()

alas LocaleInfo no has a setLocale;
the app I working on has 2 locales: en, fr
which can be re-set on the fly by the user.

any assistance would be greatly appreciated
thx
B

Re: NumberFormat

[Yegor]

StrongSteve,

I think you discovered a bug. I tried your code and I am getting a JS
error too. Windows.alert() in front of format() removes the error.
Hosted mode works either way. It might be a bug compiler's
optimization. A one-liner like that is probably inlined by the
compiler.

You should log this issue to the GWT issue tracker at
http://code.google.com/p/google-web-toolkit/issues/list

[Javascript Error] NumberFormat

[StrongSteve]

Hello,

I experience the following - from my point of view unexplainable -
behaviour when using the GWT NumberFormat
(com.google.gwt.i18n.client.NumberFormat). I am using GWT 2.0.3,
Eclipse Ganymed and IE8/FF3.6.

Within my client package I have a static helper class which contains
the following method:



public class Utils {
  ...
  public static final NumberFormat DOUBLE2_FORMAT =
NumberFormat.getFormat("##.00");
  ...

  public String formatDouble2(double d) {
return DOUBLE2_FORMAT.format(d);
  }

  ...
}



Using the code above I get a javascript error when using the
formatDouble2 method. Compiling the GWT code in a "detailed" way and
the javascript error message is something like
com...i18n.client.positivePrefix is null or not an object. The GUI
gets stuck and the application is no longer usable.

So how did I solve it?
During debug instrumentalization I found two ways. Unfortunately I can
not explain either of them - so I was hoping someone can explain me
why it works! ;)

Adding a Window.alert(...) into the formatDouble2 and everything works
fine. Why!?




public class Utils {
  ...
  public static final NumberFormat DOUBLE2_FORMAT =
NumberFormat.getFormat("##.00");
  ...

  public String formatDouble2(double d) {
Window.alert("Utils: inside formatDouble2 d=" +d);
return DOUBLE2_FORMAT.format(d);
  }

  ...
}



The solution I am currently using is to only use pattern itself as a
static member and create the NumerFormat within the method. This works
too.





public class Utils {
  ...
  public static final String DOUBLE2_FORMAT_PATTERN = "##.00";
  ...

  public String formatDouble2(double d) {
return NumberFormat.getFormat(DOUBLE2_FORMAT_PATTERN).format(d);
  }

  ...
}



BTW, changing the public static to private static did not work either.

Thanks in Advance for your help!
Stefan

Re: NumberFormat/DateTimeFormat reusability

[cretz]

Since you are in JavaScript, thread safety should not matter as far as
concurrent updates to object state. Regardless, you can see from the
code in both classes that the state is not really changed once the
pattern has been parsed.

Of course, there can be memory size issues if you store lots objects
statically versus creating as necessary (a CPU issue). That is your
decision based on your design.

NumberFormat/DateTimeFormat reusability

[Evgeny Shepelyuk]

Hello,

Are classes mentioned in subject thread-safew and reusable.
For instance if i'm using them in cell renderer in GXT grid for formatting  
value.
Should i create instance each time i need to format value or instance can  
be created once and then reused ?

Are NumberFormat and DateFormat reusable ?

[jk]

Hello,

I was unable to find any info regarding my questions. Are those 2
classes from com.google.gwt.i18n.client package are reusable ?
For example if i'm using grid cell renderer in GXT should i create new
instance each time i need to format value
or i can create formatter instance once and reuse it for further
formatting whenever it's required ?

NumberFormat problems(8 decimal places)

[Tercio]

Hi!

I have a NumberFormat with 8 decimal places, that the code:

NumberFormat format = NumberFormat.getFormat("#,##0.");
System.out.println(format.format(1234.5678d));

When I run, it prints: "1,234.7852517"

But should print: "1,234.5678"

If I reduce the zeros to 6, it works("1,234.567800")

Is this a bug or I'm doing something wrong?

Thanks.

NumberFormat not understanding its own output?

[Jaroslav Záruba]

I can't get NumberFormat working, it seems like it can't parse its own
output.

I have copied following from the watch-panel in Eclipse:
/*
 * NumberFormat decimalFormat =
 * com.google.gwt.i18n.client.NumberFormat.getDecimalFormat();
 */
"decimalFormat.format(1234.5)"= "1 234,5"
"decimalFormat.parse("1 234,5")" => java.lang.NumberFormatException!?
"decimalFormat.parse("1.234,5")" => java.lang.NumberFormatException
"decimalFormat.parse("1,234.5")" => java.lang.NumberFormatException
"decimalFormat.parse("1 234.5")" => java.lang.NumberFormatException
"decimalFormat.parse("1234,5")"= 1234.5
"decimalFormat.getPattern()"= "#,##0.###"

NumberConstants of my locale:
/*
 * NumberConstants numberConstants = GWT.create
 * (NumberConstantsImpl.class); // (NumberConstantsImpl_cs)
 */
"numberConstants.decimalSeparator()"= ","
"numberConstants.groupingSeparator()"= " "
"numberConstants.monetarySeparator()"= ","
"numberConstants.monetaryGroupingSeparator()"= " "

I assume following does not matter but just in case...
...this is how my machine OS formats numbers:
Number: 123,456,789.00
Currency: 123 456 789,00 Kč
...this is how the server OS formats numbers:
Number: 123 456 789,00
Currency: 123 456 789,00 Kč

Is this a bug or am I missing something?
I assume NumberFormat should know how to parse a string it previously
returned as a result of formatting a number.

Best regards
 J. Záruba

Re: NumberFormat getCurrenyFormat()

[fatjack1...@googlemail.com]

Ok,

The reason I wasparsing it back in was to convert it from a String to
an integer. I think I have fixed part of the problem. My code now
looks like this:

NumberFormat fmt = NumberFormat.getCurrencyFormat();
String formatted = fmt.format(discountAmount);
discountAmount = Integer.parse(formatted);

However, it now comes up with US$2.57...How do I get it to remove the
US$ part?!

Jack

please provide your full code.

you print out formatted oder discountAmount?
why you parse again the formatted string back to discountAmount?

NumberFormat getCurrenyFormat()

[fatjack1...@googlemail.com]

Hi,

I am having some problems correctly displaying currency. Here is the
code I am using:

//Format the discount to two decimal places
NumberFormat fmt = NumberFormat.getCurrencyFormat();
String formatted = fmt.format(discountAmount);
discountAmount = NumberFormat.getCurrencyFormat().parse(formatted);



The discount amount field is set to some currency value for example
2.5. Now, it works fine if the value is set to 2 or more decimal
places, so it would format 2.5 to 2.58. However, if the value is
intitial set to say 3, it formats the value to 3.0!

Now, as I am using this to display the price of something, £3.0 is not
really much use. Can someone see where I am going wrong in my code or
if I need to add something??

Cheers,

NumberFormat currency format - number of decimal places based on currency code?

[Dobes]

I'm trying to format international currency values all in the same
application, and I'm switching from using my home-baked solution to
using GWT's NumberFormat.  What I can't figure out is how to determine
and change the number of decimal places for each currency.

For example, dollars would be $1,000.00 but rupees typically don't
bother with the decimal place and they put a seperator every 4 digits
instead of 3 so they are more like Rs1,.  Can GWT support this
within one compile of the application or does it always use the same
currency format within one locale, regardless of the currency code it
is given?

Thanks,
Dobes

Re: Does gwt NumberFormat support COMMA as decimal seperator?

[obesga]

Depends on locale, or maybe use a String.replace(",","."); for your
purposes

Oskar

( yes, I also hate the mess about decimal separators - every system/
locale/app can define it's own pattern. Where are standarts when you
need them ? )
