Approximation of real functions with Freud-type weights by two kinds of entire function interpolants has been studied. The first kind interpolates at finitely many points and allows approximation of functions growing exponentially at infinity [cf. \textit{F. Stenger}, J. Comput. Appl. Math. 121, No. 1--2 , 379--420 (2000; Zbl 0964.65010)]. The second kind interpolates at infinitely many points and allows approximation of a wider class of functions with faster rate of convergence.
