将Decimal类型的数据转换为字符串。 使用DecimalFormat对象的format()方法对字符串进行格式化。 输出格式化后的字符串。 下面是一个示例代码: importjava.math.BigDecimal;importjava.text.DecimalFormat;publicclassDecimalFormatExample{publicstaticvoidmain(String[]args){BigDecimalnumber=newBigDecimal("1234567890.1234567890");...
System.out.println(df.format(n)); } The program formats a double value in two formats. var df = new DecimalFormat("#.##"); We create a new instance of theDecimalFormat. We pass it a non-localized pattern string. The pattern defines a format for a decimal value with a dot followed ...
-or- Sets the monetary decimal separator. C# 複製 public virtual char MonetaryDecimalSeparator { [Android.Runtime.Register("getMonetaryDecimalSeparator", "()C", "GetGetMonetaryDecimalSeparatorHandler")] get; [Android.Runtime.Register("setMonetaryDecimalSeparator", "(C)V", "GetSetMonetary...
现在,我们可以在需要进行千分位格式化的decimal字段上添加@ThousandSeparator注解了。示例代码如下: AI检测代码解析 publicclassExample{@ThousandSeparatorprivateDoubleamount;// getter and setterpublicstaticvoidmain(String[]args){Exampleexample=newExample();example.setAmount(1000000.0);System.out.println("Before for...
If present in a pattern, the monetary decimal separator is used instead of the decimal separator. ' Prefix or suffix No Used to quote special characters in a prefix or suffix, for example, "'#'#" formats 123 to "#123". To create a single quote itself, use two in a row: "# o'...

Decimal formats are generally not synchronized. It is recommended to create separate format instances for each thread. If multiple threads access a format concurrently, it must be synchronized externally. Example // Print out a number using the localized number, integer, currency, // and percent...
You can also use forms of theparseandformatmethods withParsePositionandFieldPositionto allow you to: progressively parse through pieces of a string align the decimal point and other areas For example, you can align numbers in two ways: If you are using a monospaced font with spacing for...
