# Numeral

From UNL Wiki

**Numerals** are LRUs that represent numbers.

## Natural Language

In the UNL^{arium} framework, numerals are classified as:

- cardinal (CDN): describe quantity (“two”, “three”)
- ordinal (ORD): describe position (“first”, “second”)
- partitive (PTN): describe division (“half”, “two thirds”)
- multiplicative (MLN): describe repetition (“once”, “twice”)
- distributive (DTN): describe distributions (“in pairs”, “by the dozen”)

Numeral determiners must be classified as numerals.

## UNL

In UNL, numerals are to be replaced by numbers, without separators for thousands, and with "." for decimals. They are temporary UWs.
