Optimal relative error rational approximations to \(e^ x\)
As the author puts it: This paper rederives the results of \textit{G.Németh} on the relative error in approximating \(e^{-x}\) by rationals [Mat. Zametki 21, 581-586 (1977; Zbl 0353.41004)] by using Newman's old construction [\textit{D. J. Newman}, J. Approximation Theory 27, 284-285 (1979; Zbl 0441.41007)].
