45<H2>Description</H2>
46<P>Multiplies a vector by a scalar.</P>
47<P>During a debug build, <CODE>VECScale</CODE> is parsed as <CODE>C_VECScale</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>PSVECScale</CODE>, will be automatically substituted. You can also call <CODE>C_VECScale</CODE> and <CODE>PSVECScale</CODE> explicitly.</P>
