Unfortunately no,
https://ci.libreoffice.org/job/gerrit_linux_clang_dbgutil/53635/console shows
that unit test is failing with it - see "Value must be the nearest
representation of decimal 0.0042" message in the log. The method uses the same
technique, so no wonder :-(

Accurate and performant conversion of string to double is *not* a trivial task,
unfortunately.
