Counting in French (Switzerland)
French (français) is an indo-european language belonging to the romance group. Official language in 29 countries, including France, Belgium (with Dutch and German), Switzerland (with German, Italian and Romansh) and Canada (with English), it is spoken by about 80 million native speakers.
Switzerland counts around 1.5 million French speakers in Romandy.
Swiss French numbers are quite similar to international French numbers. In fact, three numbers only are different: septante  (soixante-dix in French from France), octante  (quatre-vingt in standard French), and nonante  (quatre-vingt-dix in French from France). Two of these numbers are also used in Belgium, namely septante and nonante. Apart from these differences, the Swiss French numbering rules are exactly the same.

French (Switzerland) numbering rules
- Digits and numbers from zero to sixteen are specific words, namely zéro , un (une in its feminine form) , deux , trois , quatre , cinq , six , sept , huit , neuf , dix , onze , douze , treize , quatorze , quinze , seize . Seventeen to nineteen are regular numbers, i.e. named after the word for ten followed by a hyphen and the unit (dix-sept [10+7], dix-huit [10+8], dix-neuf [10+9].
- The tens are specific words too from ten to ninety, namely dix , vingt , trente , quarante , cinquante , soixante , septante , octante  and nonante . Some cantons in Switzerland use huitante instead of octante. French used in Switzerland is thus based on a complete decimal system, whereas in Belgium and France, some traces from an older vigesimal system that seems to have been inherited from Celtic languages are still in use.
- Tens and units are joined with a hyphen (e.g.: quarante-six ), unless the unit is one. In that case, the word et (and) is inserted between the ten and the unit (e.g.: septante et un ).
- Cent (hundred) is set to the plural form when multiplied by a number greater than one while ending the number (e.g.: mille deux cents [1,200], but deux cent quarante-six ), or when directly before the big scale names as million, milliard (billion, 109)… (e.g.: six cents millions [600,000,000]).
- French language uses the long scale for big numbers where every new word greater than a million is one million times bigger than the previous term. Thus, un milliard is 109 (the US billion), and un billion (1012) worths a thousand US billions.
