408<h2 id="calculation">Calculation of Change Percentages</h2>
409<p>
410The percent change statistic reported for all elements in the &quot;to&quot; API Level specification is defined recursively as follows:</p>
411<pre>
412Percentage difference = 100 * (added + removed + 2*changed)
413 -----------------------------------
414 sum of public elements in BOTH APIs
415</pre>
416<p>where <code>added</code> is the number of packages added, <code>removed</code> is the number of packages removed, and <code>changed</code> is the number of packages changed.
417This definition is applied recursively for the classes and their program elements, so the value for a changed package will be less than 1, unless every class in that package has changed.
418The definition ensures that if all packages are removed and all new packages are
419added, the change will be 100%.</p>
