In fact, this goes for every single function listed in the math module's docs, except for the somewhat useless pow(). *Every* other function in math has a corresponding numpy ufunc with the exact same name. So, no, I don't think that's a compelling argument either. > And they have the same name. Isn't this what name spaces are for?

Mixing np.foo and math.foo calls is kind of a recipe for disaster in the general case, I would think.
