— such as yes, no, or unknown. Trits are sometimes jokingly called

<span class="firstterm">3-state bits</span>. A trit may be

semi-seriously referred to as <span class="firstterm">a bit and a

half</span>, although it is linearly equivalent to 1.5849625 bits (that

is, log_{2$(3)} bits).</p></dd><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="treeware.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="../T.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="trivial.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">treeware </td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"> trivial</td></tr></table></div></body></html>
