I experimented with the formula until I found some bailout tests that give the correct image. The following all work in Fracton:<div><br></div><div>| z | != 0</div><div>| z | &gt; 0</div><div>abs( z ) != 0</div><div>abs( z ) &gt; 0</div>
<div><br></div><div>The next one generated an image that is correct except for a few thin tendrils inside the brot. I think it is because of negative 0.</div><div><br></div><div>z != 0<br><div><br><div class="gmail_quote">
