It would be useful to fix it in general: a real number power a positive real number is something that is always well defined. And actually, the following does work sage: a = SR(2) ^ cos(3) sage: a 2^cos(3) sage: a.numerical_approx() 0.503480393603062 -- You received this message because you are subscribed to the Google Groups "sage-support" group.
