022 * {@link NumberConverter} implementation that handles conversion to

024 * <p>
025 * This implementation can be configured to handle conversion either
026 * by using BigInteger's default String conversion, or by using a Locale's pattern
027 * or by specifying a format pattern. See the {@link NumberConverter}
028 * documentation for further details.
029 * <p>
030 * Can be configured to either return a <i>default value</i> or throw a
031 * <code>ConversionException</code> if a conversion error occurs.
