For most fractional numbers, the ordinal number is used to indicate the denominator of the fraction. While mil·lèsim and its forms are most often used to represent the ordinal and fraction for 1000, milè is used to form the abbreviation 1000è. Exceptions to this rule include mig (“half”), terç (“third”), quarter (“quarter”), milionèsim (“millionth”), bilionèsim (“billionth”), ....

The feminine form of the ordinal is usually used as the collective noun for a set of like objects of that size. Instead of milena or mil·lèsima, miler or milenar is used. Exceptions to the usual rule include parell (“set of 2”), qüern (“set of 4”), centenar (“set of 100”), grossa (“set of 144”), miler (“set of 1000”), and milenar (“1000”).
