Usage:
    from num2word_FR import to_card, to_ord, to_ordnum
    to_card(1234567890)
    to_ord(1234567890)
    to_ordnum(12)

History:
    0.5: Use high ascii characters instead of low ascii approximations
         String interpolation where it makes things clearer
         to_currency() added [to_year works by default]
