 * {@link NumberConverter} implementation that handles conversion to

 * or by specifying a format pattern. See the {@link NumberConverter}
 * documentation for further details.
 * <p>
 * Can be configured to either return a <i>default value</i> or throw a
 * <code>ConversionException</code> if a conversion error occurs.
