Hi,
From the equation you posted it sounds like your recommendation is to compute
`e` from a truncated Taylor series, and then raise that number to the `x`th
power. But we already know "the" double-precision value of `e`, a.k.a.
`exp(1)`. So the recommended alternative would be more work than using
double-precision `e` and then raising _that_ to the `x`th power.
So this makes me think that I missed your point. Could you please try
elaborating on your recommendation?
