What about helper classes instead?

     class myComplex;  
     
     class mycmplx : public cmplx
     {
     
             public:
     
                     mycmplx(const Complex& c) : cmplx(c.re, c.im) {};
       
     };
     
     class myComplex : public Complex
     {
     
             public:
     
                     myComplex(const cmplx& c) {this->re = c.real(); this->im = c.imag(); };  
     
     };
  
As far as I can see, this does the trick quite nicely. Looks like I need to
add a few more constructors and operators, but apart from that it seems to
work.

The cast 

        const cmplx c = sqrt(G);
        s->multiply(CAST_TO_COMPLEX(c));

is then replaced with

        const mycmplx x = sqrt(G);
        s->multiply(myComplex(x));

a constructor invocation. I tend to say, this should be equivalent to your
xlate_function. True?

Thanks,
Marc
