Description:
<p> Some results are established giving conditions on $f(x)$ so that its main diagonal Padé approximation $R_n(x)$ is of the form $P_n(x)/P_n(-x)$, where $P_n(x)$ is a polynomial in $x$ of degree $n$. A number of applications to special functions are presented. Numerical computations are given for the gamma function using the "bignum" arithmetical facilities of formula manipulation languages REDUCE2, FORMAC. </p>
