When I first discovered this, I was computing: numpy.exp(-x**2) If you try x = 26.7, you'll get 2.4877503498797906e-310 I then confirmed this by dividing 1. by 2. until python decided the answer was 0.0 -gideon _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
