I keep getting error in my iPhone programing when I try to use pi. I'm trying float pNumber = 100*cos(2 * pi * (days/23)); But i get errors that say: _pi, referenced from _pi$non_lazy_ptr I saw somewhere on the internet to use M_PI and it compiles but I don't think it gives me the correct calculation. When I try: float pNumber = 100*cos(2 * M_PI * (15746/23)); I get 0 Thanks
