Description
`NumberFormat` adds support for formatting a number in its compact form. Compact number formatting refers to the representation of a number in a short or human readable form. For example, in the en_US locale, 1000 can be formatted as "1K" and 1000000 can be formatted as "1M", depending upon the style specified by `NumberFormat.Style`. The compact number formats are defined by LDML's specification for [Compact Number Formats](http://unicode.org/reports/tr35/tr35-numbers.html#Compact_Number_Formats). To obtain an instance, use one of the factory methods given by `NumberFormat` for compact number formatting. For example:

``` 
NumberFormat fmt = NumberFormat.getCompactNumberInstance(Locale.US, NumberFormat.Style.SHORT);
String result = fmt.format(1000);

``` 
The example above results in "1K".
