<p dir="auto">顺便说一下，调用原始 Rails 代码将返回以下结果：</p>
<pre class="notranslate"><code class="notranslate">QuadTile.tile_for_point(35.2000381, 114.6629926)
=> 3875963095
</code></pre>
<p dir="auto">这匹配：</p>
<pre class="notranslate"><code class="notranslate">     id      | latitude  | longitude  | changeset_id | visible |         timestamp          |    tile    | version 
-------------+-----------+------------+--------------+---------+----------------------------+------------+---------

<p dir="auto">Thank you very much for your guidance. I currently have a clear understanding of how this value was obtained, but I would like to clarify what the formula inside looks like? Just like how num integrates numbers in Java, what is the QuadTile formula that depends on it? Could you please explain it to me? Thank you</p>
