Follow-up Comment #4, bug #64801 (project octave): [(Erreur - Introuvable)] I don't know either. But you are right a floating point problem. In fact I am writing the kyosu library based on eve which implements in scalar and simd complex and caley-dickson (quaternions octonions x-nions) and classical functions on them. I used octave to verify some of my ouputs and I spotted this problem. What I think is that a complex function is meant to return pure imaginary or real values in quite obvious an general circumstances it is better that it does. However the problem can be complicated to fix. I just wanted to signal the issue. Sorry for the noise. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?64801> _______________________________________________ Message posté via Savannah https://savannah.gnu.org/
