Numbers and the 1990 spelling reform
Before the 1990 French spelling reform, any two-word number less than 100 that didn't use the word et had hyphens between the components. After the reform, any two-or-more-word number takes hyphens between the components. This is used to distinguish, for example, soixante-et-un tiers (61/3) from soixante et un-tiers (60⅓). Included here are the post-reform numbers. See also Appendix:French spellings.

Numbers from twenty to ninety-nine

 * Note: Septante and nonante forms are used in Belgium, Switzerland, the Democratic Republic of Congo, and Acadia. Huitante is used in part of Switzerland.

Letter s
Some numbers take plural endings. The word cent becomes plural only with exact multiples of 100 greater than 100. For example, deux-cents, trois-cents, quatre-cents and others are written with an s at the end, but not, for example, deux-cent-un. The word mille is invariable; it never takes s. All the other numbers take s when there is more than one of them, e.g. deux-millions-trois-mille, but not *un-millions.

Latin forms
In an enumeration, the adverbs primo, secundo, ... of Latin ordinals (primus, secundus, ...) may be used in place of the regularly-formed adverbs (premièrement, deuxièmement, ...):
 * Quand vous verrez un aveugle marcher seul, cédez lui le haut du pavé: vous le devez, primo par humanité, secundo par prudence; parce qu'en voulant tâter le mur avec son bâton, il vous le donnera dans les jambes.

Inserting an entry between elements labelled with cardinal numbers, French uses Latin adverbs, beginning with bis ("twice"), and continuing ter, quater, .... This occurs in house-numbering and when inserting new provisions into legal codes. Inserting further elements has resort to letters; e.g. the provisional form of Loi 2003-1312 had consecutive articles 18, 18 bis A, 18 bis, 18 ter, 19.

Digit abbreviations
Ordinal abbreviations using digits are as follows:

The same superscripts are used with roman numerals for centuries (e.g. le XIXe siècle "the nineteeth century") and first monarchs (e.g. François Ier, Élisabeth Ire).
