Fixed-point math is a system by which integer variables can represent fractional values with a fixed precision "behind" the decimal point. Fixed-point math is much faster to execute than floating-point math, and should be used when a limited amount of fractional precision is sufficient (such as 4ths, or 10ths, or 128ths).<p><dl compact><dt><b>Note:</b></dt><dd>Library functional but not currently complete </dd></dl><hr size="1"><address style="align: right;"><small>Generated on Fri Oct 15 03:50:24 2004 for Procyon AVRlib by<a href="http://www.doxygen.org/index.html"><img src="doxygen.png" alt="doxygen" align="middle" border=0 > </a>1.3.6 </small></address></body></html>?? 快捷鍵說明
