It exactly sounds like that we can benefit from specialized &amp;quot;non-negative&amp;quot; or &amp;quot;non-NaN&amp;quot; types, either implemented in the library (with a limited operator overloading) or in the compiler level (via static range analyses).</text><parent_chain></parent_chain></comment><story><title>Boosting zopfli performance</title><url>http://roartindon.blogspot.com/2016/04/boosting-zopfli-performance.html</url></story>
