functions in test3.i - t

             test3  
          or test3, npass  
 
     Computes the ratio r which solves 1 + r^2 + r^3 +...+ r^n = s,  
     given n and s.  If NPASS is given, the calculation is repeated  
     that many times (actually the equation is solved many times for  
     each pass).  The worker routine invgeom can actually be  
     vectorized; the vector version is gseries_r in series.i.  */
