Hello, I have a problem with the attribute "Listable". It is said in documentation that a function is threaded over lists if one of its attributes is "Listable". Neither the function N nor the function ComplexExpand has "Listable" among its attributes and however both of them are mapped on lists of numbers. Can someone explain me ? Thanks in advance, J.M.
