Some tests in French (Belgium) are not correct.

[Vincent-Stragier]

French (Belgium) is a really complex with numbers and even as a native speaker, numbers are quite difficult to write correctly. I've been through the tests and some seem to be wrongs.

Some interesting references from Wikipedia (maybe not the most reliable sources, but at least they exist):

Big numbers names (in French)
Numbers in French (in French)

Alternative (edit)

I'd really like this package to handle all the languages, but for the time being, I made my own package to handle all the French numbers. More information here: https://pypi.org/project/nombres-vers-lettres/. Feel free to open issues, or use it to improve this package (although my code is more spaghetti like, but it is also tested and linted).

The correct tests would be:

 (999, 'neuf cent nonante-neuf'), 
 (7232, 'sept mille deux cent trente-deux'),

	(1000000000000000000, 'un trillionsième') # over 1e18 is not supported

The correct tests would be:

    (1000000,  'millionième'),
    (1000000000000000, 'billiardième'),
    (1000000000000000000, 'trillionième')  # over 1e18 is not supported

Also, you should test for (2000000, 'deux millionièmes'),, etc.
