* The base class for a Rounder used by ICU Decimal Format.
*
* <p>A Rounder must implement the method {@link #apply}. An implementation must:
*
* <ol>
* <li>Either have the code <code>applyDefaults(input);</code> in its apply function, or otherwise
* ensure that minFrac, maxFrac, minInt, and maxInt are obeyed, paying special attention to
* the case when the input is zero.
* <li>Call one of {@link FormatQuantity#roundToIncrement}, {@link
* FormatQuantity#roundToMagnitude}, or {@link FormatQuantity#roundToInfinity} on the input.
* </ol>
*
* <p>In order to be used by {@link CompactDecimalFormat} and {@link ScientificFormat}, among
* others, your rounder must be stable upon <em>decreasing</em> the magnitude of the input number.
* For example, if your rounder converts "999" to "1000", it must also convert "99.9" to "100" and
* "0.999" to "1". (The opposite does not need to be the case: you can round "0.999" to "1" but keep
* "999" as "999".)

*
* If one of the first four methods is used (those of the form <code>setXxxYyy</code>), the value
* will be interpreted literally. If one of the second four methods is used (those of the form
* <code>setXxxYyyPattern</code>), locale-specific symbols for the plus sign, minus sign, percent
* sign, permille sign, and currency sign will be substituted into the string, according to Unicode
* Technical Standard #35 (LDML) section 3.2.
*
* <p>Literal characters can be used in the <code>setXxxYyyPattern</code> methods by using quotes;
* for example, to display a literal "%" sign, you can set the pattern <code>'%'</code>. To display
* a literal quote, use two quotes in a row, like <code>''</code>.
*
* <p>If a value is set in both a <code>setXxxYyy</code> method and in the corresponding <code>
* setXxxYyyPattern</code> method, the one set in <code>setXxxYyy</code> takes precedence.
*
* <p>For more information on formatting currencies, see {@link CurrencyFormat}.
*
* <p>The parameter is taken by reference by these methods into the property bag, meaning that if a
* mutable object like StringBuilder is passed, changes to the StringBuilder will be reflected in
* the property bag. However, upon creation of a finalized formatter object, all prefixes and
