Comment (by robertwb):
I'm surprised the exponential integral is not efficiently implemented
elsewhere already. Note, however, that you could compute this more
efficiently by keeping track of the single value (sgn*alpha_pow*denom)
which changes by a constant factor of -1/(alpha * t) each iteration (if
this is a bottleneck). Doctests on these functions might be useful as
well.
