I did a Quadratic Solver for Casio FX3650P: Instead of using a special number for signaling complex roots. I CRASH the program, on purpose, by taking square root of negative discriminant. (complex roots = X +/ Y * I, stored in memory X, Y) If user is still not warned about roots being complex, I don't know what will :) Edit: I had revised the solver, allowed for adjustable discriminant (if more precise available). Since discriminant is shown, it's sign signaled real or complex roots.
