Atom

Function: atom (<expr>) Returns true if <expr> is atomic (i.e. a number, name or string) else false. Thus atom(5) is true while atom(a[1]) and atom(sin(x)) are false (asuming a[1] and x are unbound).

There are also some inexact matches for atom. Try ?? atom to see them.

(%o1)                                true
