I'm not sure what all the fuss is about:
from math import pi, sin sin(pi/2) 1.0
Try cos(pi/2) or sin(pi/6). Or try: sin(pi/4) == sqrt(2)/2 tan(pi/4) == 1 tan(pi/3) == sqrt(3) And even tan(pi/2), which ought to be an error, but isn't. These are, of course, limitations due to the finite precision of floats. But Julia gets the equivalent degree-based calculations all correct, except for tan(90) where it returns Inf (NAN would be better, as the limit from below and the limit from above are different). -- Steve
