Free42 possible accuracy flaw

[J-F Garnier]

I may have identified an accuracy flaw in the power operation in Free42/Decimal.

This came from the last [VA] SRC #010 - Pi Day 2022 Special thread where a calculation done by two methods gave significantly different results, with no clear explanation.

I found a problem with this calculation:
(1+1/X)^X [1]
with X=1E8.
A comparison with the expended and mathematically equivalent expression:
exp( X * ln(1+1/X) ) [2]
gives the following results
[1] 2.718281814867636217652977244308419
[2] 2.718281814867636217652977243009177

Although we could expect expression [2] to be less accurate due to the intermediate calculations, it turns out that result [2] is correct (according to Wolfram reference) and result [1] is in error in its last 7 digits.

Checked on latest Free42 3.0.10.
