  Perhaps something like this:

#declare C = <0,0,0>;
#declare Clen = 0;
#declare TotalW = 0;
#declare Ind = 0;
#while(Ind<Amount)
  #declare C = C+vnormalize(V[Ind])*W[Ind];
  #declare Clen = Clen+vlength(V[Ind])*W[Ind];
  #declare TotalW = TotalW+W[Ind];
  #declare Ind=Ind+1;
#end
#declare C = vnormalize(C/TotalW)*(Clen/TotalW);
