* <p><em><strong>This class is currently not implemented in GNUstep! All set
* methods will work, but stringForObject: will ignore the format completely.
* The documentation below describes what the behavior SHOULD
* be...</strong></em></p>
*
* <p>A specialization of the [NSFormatter] class for generating string
* representations of numbers ([NSNumber] and [NSDecimalNumber] instances) and
* for parsing numeric values in strings.</p>
*
* <p>See the [NSFormatter] documentation for description of the basic methods
* for formatting and parsing that are available.</p>
*
* <p>There are no convenience initializers or constructors for this class.
* Instead, to obtain an instance, call alloc init and then -setFormat: .</p>
*
* <p>The basic format of a format string uses "#" signs to represent digits,
* and other characters to represent themselves, in a context-dependent way.
* Thus, for example, <code>@"#,###.00"</code> means to print the number
* ending in .00 if it has no decimal part, otherwise print two decimal
* places, and to print one comma if it is greater than 1000. Thus, 1000
* prints as "1,000.00", and 1444555.979 prints as "1444,555.98" (see
* -setRoundingBehavior:).</p>
*
* <p>After setting the format, you may change the thousands separator and
* decimal point using set methods, or by calling -setLocalizesFormat: .</p>
*
* <p>You may set separate formats to be used for positive numbers, negative
* numbers, and zero independently.</p>
*
* <p>In addition, this class supports attributed strings (see
* [NSAttributedString]), so that you can specify font and color attributes,
* among others, to display aspects of a number. You can assign specific sets
* of attributes for positive and negative numbers, and for specific cases
* including 0, NaN, and nil... </p>
