Hi-- exp() doesn't seem to evalf its arguments when evalf is called on it. This is probably a bug, and if so I'll file an issue. In the mean time, is there an easy way to get sympy to convert exp(x) expressions to E**x expressions?
exp(t*sqrt(5)).n() -> exp(t*sqrt(5)) E**(t*sqrt(5)).n() -> E**(2.23606797749979*t) I think this is causing me some trouble when converting complex expressions to numpy via lambdify. I'm trying to lambdify a result from dsolve that includes square roots of very large integers (not sure where those large integers are coming from). When I try to execute the result, I get "AttributeError: 'int' object has no attribute 'sqrt'". I'll see if I can get the lambdify to trip up with a simple set of inputs. Right now this is the culmination of a 100 cell IPython notebook... -- You received this message because you are subscribed to the Google Groups "sympy" group.
