--- Comment #10 from Eike Rathke <erack at redhat.com> ---
Fwiw, this was implemented with
https://gerrit.libreoffice.org/plugins/gitiles/core/+/b0fdf6cf11ee46d46925e9cd9fa2768a1b49bb64%5E!/
for bug 69293.

The same result -2 for (-8)^(6004799503160661/2^54)
There may be no rounding error but an accuracy limit here, see
https://www.wolframalpha.com/input/?i=6004799503160661%2F2%5E54

Perhaps reformulating (or even omitting?) the rtl::math::approxEqual() would be
an option? Didn't dig into it.
