+ * 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.
