QtCore.QLocale().toLong() doesn't report whether it succeeded

Despite help(QtCore.QLocale().toLong) reads that the function returns tuple[int, bool], the function actually returns a single int value. The docs confuse more than help.

On the other hand, QtCore.QLocale().toInt returns a tuple, in accordance with the help.

So, the MWE is the following:

from PySide6 import QtCore  # or from PySide2
print(QtCore.QLocale().toLong('42'))

The expected output is (42, True), however the actual one is just 42.

The same refers to QtCore.QLocale().toULong, but not to any other to-number function of the family.
