Examples of org.apache.struts2.components.Number

org.apache.struts2.components.Checkbox
Format Number object in different ways.
The number tag will allow you to format a Number in a quick and easy way, based on the java.text.NumberFormat class. There are four basic number types, a number, a currency, a percentage and an integer. If a currency is specified, the number format will match the given currency. Further parameters can be overridden as needed.
If a type is not defined, it will finally fall back to the default NumberFormat.getNumberInstance() formatting.
Note: If the requested Number object isn't found on the stack, a blank will be returned.

Configurable attributes are :-
- name
- currency - you can specify your own currency or as an OGNL expression
- type - if not specified try to find base on struts.number.format property
- groupingUsed - see NumberFormat.isGroupingUsed
- maximumFractionDigits - see NumberFormat.setMaximumFractionDigits
- maximumIntegerDigits - see NumberFormat.setMaximumIntegerDigits
- minimumFractionDigits - see NumberFormat.setMinimumFractionDigits
- minimumIntegerDigits - see NumberFormat.setMinimumIntegerDigits
- parseIntegerOnly - see NumberFormat.isParseIntegerOnly
- roundingMode - see below
Possible values for rounding mode are :-
- ceiling
- down
- floor
- half-down
- half-even
- half-up
- unnecessary
- up
Examples
```
  <s:number name="invoice.total" type="currency" currency="XYZ" /> <s:number name="invoice.quantity" type="number" /> <s:number name="invoice.discount" type="percentage" /> <s:number name="invoice.terms" type="integer" />  
```
