Both methods, using fmin/fmax and using MIN/MAX will do what you want. But as was pointed out anything you do to optimize something that's relatively straight forward, will get re-optimized by the compiler. So readability becomes more important in this case. Re: calculator issue with pointers only on fmin fmax from another class 10 Years Ago by tinstaafl I'm wondering if the problem is in using a different compiler or diffferent compiler settings.
