   * <p>It can be configured to use one of these variants: integer,
   * number, currency or percent.
   *
   * <p>Alternatively, a <strong>formatting pattern</strong> can be used. This can either be a locale-dependent
   * or locale-independent formatting pattern. When looking up a formatting pattern, a mechansim
   * similar to resource bundle lookup is used. Suppose the locale is nl-BE, then first a formatting
   * pattern for nl-BE will be sought, then one for nl, and if that is not
   * found, finally the locale-independent formatting pattern will be used.
   *
   * <p>Note: the earlier statement about the fact that this class uses java.text.DecimalFormat
   * is not entirely correct. In fact, it uses a small wrapper class that will either delegate to
   * java.text.DecimalFormat or com.ibm.icu.text.DecimalFormat. The com.ibm version will automatically
   * be used if it is present on the classpath, otherwise the java.text version will be used.
