blocks|key|202473|text|以下是有效的方法。它有点难看，但它满足了合同的要求：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|202474|NumberFormat+nf+=+NumberFormat.getCurrencyInstance();

decimalFormatSymbols.setCurrencySymbol("");

String+newPattern+=+pattern.replace("\u00A4",+"").trim();
NumberFormat+newFormat+=+new+DecimalFormat(newPattern);

The following works. It's a bit ugly, but it fulfils the contract:

<pre><code>NumberFormat nf = NumberFormat.getCurrencyInstance();
DecimalFormatSymbols decimalFormatSymbols = ((DecimalFormat) nf).getDecimalFormatSymbols();
decimalFormatSymbols.setCurrencySymbol("");
((DecimalFormat) nf).setDecimalFormatSymbols(decimalFormatSymbols);
System.out.println(nf.format(12345.124).trim());
</code></pre>

You could also get the pattern from the currency format, remove the currency symbol, and reconstruct a new format from the new pattern:

<pre><code>NumberFormat nf = NumberFormat.getCurrencyInstance();
String pattern = ((DecimalFormat) nf).toPattern();
String newPattern = pattern.replace("\u00A4", "").trim();
NumberFormat newFormat = new DecimalFormat(newPattern);
System.out.println(newFormat.format(12345.124));
</code></pre>

blocks|key|3979978|text|改为使用空字符串进行设置：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3979979|DecimalFormat+formatter+=+(DecimalFormat)+NumberFormat.getCurrencyInstance(Locale.US);
DecimalFormatSymbols+symbols+=+formatter.getDecimalFormatSymbols();
symbols.setCurrencySymbol("");+//+Don't+use+null.

Set it with an empty string instead:

<pre><code>DecimalFormat formatter = (DecimalFormat) NumberFormat.getCurrencyInstance(Locale.US);
DecimalFormatSymbols symbols = formatter.getDecimalFormatSymbols();
symbols.setCurrencySymbol(""); // Don't use null.
formatter.setDecimalFormatSymbols(symbols);
System.out.println(formatter.format(12.3456)); // 12.35
</code></pre>

blocks|key|5594794|text|例如，给定的解决方案有效，但最终为欧元留下了一些空格。我最终做了：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5594795|numberFormat.format(myNumber).replaceAll("[%5E0123456789.,]","");|code-block|syntax|javascript|5594796|这确保了我们具有不带货币或任何其他符号的数字的货币格式。|5594797|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

The given solution worked but ended up lefting some whitespaces for Euro for example.
I ended up doing :

<pre><code>numberFormat.format(myNumber).replaceAll("[^0123456789.,]","");
</code></pre>

This makes sure we have the currency formatting for a number without the currency or any other symbol.

blocks|key|1219503|text|只需使用NumberFormat.getInstance()而不是NumberFormat.getCurrencyInstance()，如下所示：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1219504|val+numberFormat+=+NumberFormat.getInstance().apply+{
++++this.currency+=+Currency.getInstance()
}

Just use <code>NumberFormat.getInstance()</code> instead of <code>NumberFormat.getCurrencyInstance()</code> like follows:

<pre><code>val numberFormat = NumberFormat.getInstance().apply {
 this.currency = Currency.getInstance()
}

val formattedText = numberFormat.format(3.4)
</code></pre>

blocks|key|1219484|text|也许我们可以只使用替换或substring来获取格式化字符串的数字部分。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1219485|NumberFormat+fmt+=+NumberFormat.getCurrencyInstance(Locale.getDefault());
fmt.format(-1989.64).replace(fmt.getCurrency().getSymbol(),+"");
//fmt.format(1989.64).substring(1);++//this+doesn't+work+for+negative+number+since+its+format+is+-$1989.64|code-block|syntax|javascript|1219486|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Maybe we can just use replace or substring to just take the number part of the formatted string.

<pre><code>NumberFormat fmt = NumberFormat.getCurrencyInstance(Locale.getDefault());
fmt.format(-1989.64).replace(fmt.getCurrency().getSymbol(), "");
//fmt.format(1989.64).substring(1); //this doesn't work for negative number since its format is -$1989.64

<pre><code>DecimalFormat df = new DecimalFormat();

Works with many types for <code>num</code>, but don't forget to <a href="https://stackoverflow.com/questions/3730019/why-not-use-double-or-float-to-represent-currency">represent currency with BigDecimal</a>.

For the situations when your <code>num</code> can have more than two digits after the decimal point, you could use <code>df.setMaximumFractionDigits(2)</code> to show only two, but that could only hide an underlying problem from whoever is running the application.

there is a need for a currency format "WITHOUT the symbol", when u got huge reports or views and almost all columns represent monetary values, the symbol is annoying, there is no need for the symbol but yes for thousands separator and decimal comma.
U need 

<pre><code>new DecimalFormat("#,##0.00");
</code></pre>

and not

<pre><code>new DecimalFormat("$#,##0.00");
</code></pre>

I am using <code>NumberFormat.getCurrencyInstance(myLocale)</code> to get a custom currency format for a locale given by me. However, this always includes the currency symbol which I don't want, I just want the proper currency number format for my given locale without the currency symbol. 

Doing a <code>format.setCurrencySymbol(null)</code> throws an exception..

Format currency without currency symbol
