title: What is the maximum length of Double.toString(d)?
body: <p>My experimentation suggests a bound of 24, which is reached by <code>-Double.MIN_NORMAL</code>, which results in</p>
  
  <pre><code>-2.2250738585072014E-308
  </code></pre>
  
  <p>...but I can't prove it, nor come up with a conclusive reason why no other value should beat <code>-MIN_NORMAL</code>.</p>
