[New-bugs-announce] [issue39274] Conversion from fractions.Fraction to bool

[François Durand]

New submission from François Durand <fradurandpub at gmail.com>:

As of now, fractions.Fraction.__bool__ is implemented as: ``return a._numerator != 0``. However, this does not necessary return a bool (which would be desired). In particular, when the numerator is a numpy integer, this returns a numpy bool instead. Another solution would be to implement fractions.Fraction.__bool__ as: ``return bool(numerator)``. What do you think?
