41<H2>Description</H2>
42<P>This function computes a unit vector from <code><em><strong>src</strong></em></code> and places it in <code><em><strong>unit</strong></em></code>.</P>
43<P>During a debug build, <code>VECNormalize</code> is interpreted as <code>C_VECNormalize</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>PSVECNormalize</CODE>, will be automatically substituted. You can also call each of <code>C_VECNormalize/PSVECNormalize</code> explicitly.</P>
