38<H2>Return Values</H2>
39<P>Returns the dot product of <SPAN class="argument">p</SPAN> and <SPAN class="argument">q</SPAN>.</P>
40
41<H2>Description</H2>
42<P>Computes the dot product of two given quaternions.</P>
43<P>During a debug build, <CODE>QUATDotProduct</CODE> is parsed as <CODE>C_QUATDotProduct</CODE>, which is a normal C language version. During a non-debug build for a Broadway processor, the paired-singles equivalent of this function, <CODE>PSQUATDotProduct</CODE>, will be automatically substituted. You can also call <CODE>C_QUATDotProduct</CODE> and <CODE>PSQUATDotProduct</CODE> explicitly.</P>
