When x is close to 1, then 1 - x is a small number and might be rounded down to 0. After division by n!, all the En for odd n look similar (but not identical) to each other. PARI/GP: provides erfc for real and complex arguments, via tanh-sinh quadrature plus special cases. W. you could try here

The error function is related to the cumulative distribution Φ {\displaystyle \Phi } , the integral of the standard normal distribution, by[2] Φ ( x ) = 1 2 + 1 The pairs of functions {erff(),erfcf()} and {erfl(),erfcl()} take and return values of type float and long double respectively.

Similarly, the En for even n look similar (but not identical) to each other after a simple division by n!.

For large enough values of x, only the first few terms of this asymptotic expansion are needed to obtain a good approximation of erfc(x) (while for not too large values of doi:10.3888/tmj.16–11.Schöpf, Supancic ^ E. Taylor series[edit] The error function is an entire function; it has no singularities (except that at infinity) and its Taylor expansion always converges.
