title: Where can I find the source code for Java's Square Root function?
body: <p>I know that <code>Math.sqrt</code> calls   <code>StrictMath.sqrt(double a)</code>.  </p>
  
  <p>Method signature in <code>StrictMath</code> class:  </p>
  
  <pre><code>public static native double sqrt(double a);
  </code></pre>
  
  <p>I was wanting to look at <strong>the actual implementation code</strong> used to calculate it.  </p>
