35<H2>Description</H2>
36<P>This function receives radians as an <code><A href="fx32.html">fx32</A></code> type and returns the result as <code><A href="fx64c.html">fx64c</A></code>. Accuracy is to at least 7 decimal places and usually to 8 decimal places. Approximations are made using internal progressive calculations. Use this function when <code><A href="FX_SinIdx.html">FX_SinIdx</A></code> is not sufficiently accurate.</P>
