        /*/*from   ww w  .j a v a 2s. c o  m*/
         *I needed 123,45, locale independent. 
         *I tried NumberFormat.getCurrencyInstance().format( 12345.6789 ); but that is locale specific.
         *I also tried 
        DecimalFormat df = new DecimalFormat( "0,00" );
        df.setDecimalSeparatorAlwaysShown(true);
        df.setGroupingUsed(false);
        DecimalFormatSymbols symbols = new DecimalFormatSymbols();
        symbols.setDecimalSeparator(',');
        symbols.setGroupingSeparator(' ');
        df.setDecimalFormatSymbols(symbols);
            
        but that would not switch off grouping. 
        Although I liked very much the (incomplete) "BNF diagram" in http://docs.oracle.com/javase/tutorial/i18n/format/decimalFormat.html
        in the end I decided to calculate myself and take eur+sparator+cents
            
        This function will cut off, i.e. floor() subcent values
        Tests:
        System.err.println(utils.currencyFormat(new BigDecimal(0), ".")+"\n"+utils.currencyFormat(new BigDecimal("-1.10"), ",")+"\n"+utils.currencyFormat(new BigDecimal("-1.1"), ",")+"\n"+utils.currencyFormat(new BigDecimal("-1.01"), ",")+"\n"+utils.currencyFormat(new BigDecimal("20000123.3489"), ",")+"\n"+utils.currencyFormat(new BigDecimal("20000123.3419"), ",")+"\n"+utils.currencyFormat(new BigDecimal("12"), ","));
            
        results
        0.00
        -1,10
        -1,10
        -1,01
        20000123,34
        20000123,34
        12,00
            
        */
        long totalCent = value.multiply(new BigDecimal(100)).intValue();
        long eurOnly = value.longValue();
        long centOnly = Math.abs(totalCent % 100);
        StringBuffer res = new StringBuffer();
        res.append(eurOnly);
        res.append(decimalDelimiter);
        if (centOnly < 10) {
            res.append('0');
        }
        res.append(centOnly);
        return res.toString();
    }
}
