Are the following correct?

198,647: cent-quatre-vingt-dix-huit-mille-six-cent-quarante-sept

318,431: trois-cent-dix-huit-mille-quatre-cent-trente-un

2,857,566: deux-millions-huit-cent-cinquante-sept-mille-cinq-cent-soixante-six

Thank you.

  • I'm wondering if French people dictate their numéro de téléphone two by two?

    @Vim Phones numbers are not considered as regular large numbers but follow specific rules, including the two by two rule you cite.

  • They group it by two for local French numbers. If there is a 3-digit prefix (for international codes , or numbers of some other countries), they will dictate it as the whole number (ex: trois cent cinquante-huit). If there is leading "0" in the 2-digit group (eg 06), they will dictate it as "zéro-six".

Your only mistake is a missing "et" in "trente-et-un".

Here is how these numbers are written in the traditional way which is still accepted as correct and the most commonly used:

198 647: cent quatre-vingt-dix-huit mille six cent quarante-sept

318 431: trois cent dix-huit mille quatre cent trente et un

2 857 566: deux millions huit cent cinquante-sept mille cinq cent soixante-six

Since the Dec 6, 1990 rectifications, connecting all components of a numeral with dashes is allowed, albeit not mandatory:

198 647: cent-quatre-vingt-dix-huit-mille-six-cent-quarante-sept

318 431: trois-cent-dix-huit-mille-quatre-cent-trente-et-un

2 857 566: deux-millions-huit-cent-cinquante-sept-mille-cinq-cent-soixante-six

However, depending on the sources, million and milliard are subject to that simplification or not. The "Académie Française" is recommending:

2 857 566: deux millions huit-cent-cinquante-sept-mille-cinq-cent-soixante-six

Note that you do not use a comma in French to separate thousands, the comma is exclusively used as a decimal separator where English uses a dot.

Note also that while "quatre-vingts" takes an ending "s", there is no "s" in "quatre-vingt-dix-huit" so your form is correct.

"Cent nonante-huit mille" is used instead of "cent quatre-vingt-dix-huit mille" in Belgium and Switzerland.

Finally, your last guess is also correct as "million" is a regular word so must take the plural form in "deux millions ..."

  • +1. One should keep in mind that the 1990 reformed orthography is far from being the most used one, at least in France. Most textbooks and many, if not most, teachers still use the pre-1990 rules. See en.wikipedia.org/wiki/Reforms_of_French_orthography#Application and fr.wikipedia.org/wiki/….

  • So the "et" only apply in the case of un? Commented Mar 5, 2015 at 18:15
  • It is used for 21 (vingt-et-un) up to 61 (soixante-et-un), and also 61 to 91 where septante-et-un, huitante-et-un and nonante-et-un are used. On the other hand, 101 and 1001 do not use "un", i.e. are written cent un, mille un and so on.

  • On 70/80/90 in Belgium and France: septante and nonante are the prevalent forms in both countries. Huitante is used only in Switzerland, but is more frequent in some "cantons" than others. Octante is, contrary to a widespread belief, not used anymore (see francaisdenosregions.com/2017/03/26/…).

  • @Greg Oui, je suis bien au courant. Je suis même partisan d'une promotion de l'usage de septante, huitante et nonante dans toute la francophonie. Il est quand même ridicule que la France, souvent dite cartésienne, se traîne une telle casserole qui perturbe l'apprentissage du français.
