Evaluating ln(1+x) is pretty easy, a simple way is shown in the mentioned Advanced Functions Handbook. However I do not know of a straightforward method of determining ex-1. Any suggestions?

I don't see anything obvious. I tried ((e^x - 1) * x) / (x + 1 - 1) just for the heck of it, but the result doesn't appear correct. But getting 10 accurate digits in a contrived example designed to elicit rounding error is probably good enough. I would think the potential error would be immaterial for most realistic scenarios.
