Example 1

Ensure that the power function will return 0, if the exponent is 0.

        CreateIt(a,b);
        With TVec(Self) do
        try
          Ln(Base);  //First do it the normal way then fix the anomalies
          Mul(Exponent);
          Exp;
          a.FindIndexes(Exponent,'=',0);
          b.Size(a.Length,Complex);
          b.Setval(1);
          Scatter(b,a);
        finally
          FreeIt(a,b);
        end;
