39<P>Returns the distance between the two vectors.</P>

41<H2>Description</H2>
42<P>Returns the distance between vectors <SPAN class="argument">a</SPAN> and <SPAN class="argument">b</SPAN> (the distance between two points, <SPAN class="argument">a</SPAN> and <SPAN class="argument">b</SPAN>, expressed as a vector).</P>
43<P>During a debug build, <CODE>VECDistance</CODE> is parsed as <CODE>C_VECDistance</CODE>, which exists in a standard C language version. During a non-debug build using a Broadway processor, the paired singles equivalent to this function, <CODE>PSVECDistance</CODE>, is automatically substituted. You can also call <CODE>C_VECDistance</CODE> and <CODE>PSVECDistance</CODE> explicitly.</P>
