 *
 * The CompactDecimalFormat produces abbreviated numbers, suitable for display in
 * environments will limited real estate. For example, 'Hits: 1.2B' instead of
 * 'Hits: 1,200,000,000'. The format will be appropriate for the given language,
 * such as "1,2 Mrd." for German.
 *
 * For numbers under 1000 trillion (under 10^15, such as 123,456,789,012,345),
 * the result will be short for supported languages. However, the result may
 * sometimes exceed 7 characters, such as when there are combining marks or thin
 * characters. In such cases, the visual width in fonts should still be short.
 *
 * By default, there are 3 significant digits. After creation, if more than
 * three significant digits are set (with setMaximumSignificantDigits), or if a
 * fixed number of digits are set (with setMaximumIntegerDigits or
 * setMaximumFractionDigits), then result may be wider.
 *
 * At this time, parsing is not supported, and will produce a U_UNSUPPORTED_ERROR.
 * Resetting the pattern prefixes or suffixes is not supported; the method calls
 * are ignored.
