37<H2>Description</H2>
38<P>This function computes the magnitude of a vector.</P>
39<P>During a debug build, <CODE>VECMag</CODE> is parsed as <CODE>C_VECMag</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>PSVECMag</CODE>, will be automatically substituted. You can also call <CODE>C_VECMag</CODE> and <CODE>PSVECMag</CODE> explicitly.</P>
