Toki Pona nanpa-linja-n decimal number system ilo pi pana nanpa

Welcome to the Toki Pona nanpa-linja-n decimal number system.
At last, nanpa-linja-n offers an elegant solution to the challenge of representing and communicating decimal numbers consistently. kama pona tawa lipu ilo pi nasin nanpa-linja-n pi nanpa linja n pi toki pona.

nanpa-linja-n encodes decimal numbers as proper names. In sitelen pona, these names are written inside numeric cartouches.

The content of a nanpa-linja-n cartouche is a pure encoding. Each decimal digit—and each numeric delimiter, such as a decimal point—has a designated sitelen pona glyph and a corresponding Latin-letter representation. This mapping is unique and reversible, allowing the original decimal sequence to be reconstructed exactly from either form.

nanpa-linja-n does not introduce any new Toki Pona words or add anything to the Toki Pona lexicon. It is a notation system only. Any “words” discussed below are identifier strings, or proper-name labels, derived from the encoded cartouche. When a nanpa-linja-n proper name is written in the Latin alphabet, each word begins with a capital letter.

The ten Toki Pona letters i, w, t, s, a, l, u, m, p, and j represent the decimal digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, respectively, within numeric cartouches.

The letters n and e are used to structure the encoding and make the proper name derived from the cartouche pronounceable. The letters o and k, used in various combinations, represent numeric punctuation and delimiters, such as the decimal point.

Every letter in the Toki Pona Latin alphabet therefore has a distinct function within nanpa-linja-n. PDF cheat sheet

Precise decimal numbers appear everywhere: in dates, times, measurements, percentages, telephone numbers and many other forms.

nanpa-linja-n represents exact decimal numbers through proper names using a small, reusable set of digit syllables and numeric punctuation words. Once the ten digit syllables and a few separators are familiar, the same system can be used to read and write integers, decimals, fractions, dates, times and much more.

The examples below may initially look unfamiliar, but they are all constructed from the same repeating rules. You do not need to learn a separate method for each type of number.

The aim is for learners to recognise the recurring patterns and eventually read, write and understand nanpa-linja-n directly.

This table shows which syllables are allowed for each decimal digit when reading and writing a nanpa-linja-n proper name.
In strict mode, each digit has only one accepted syllable. For example, digit 1 uses we, digit 2 uses te, and digit 5 uses le.
In relaxed mode, some digits can also use extra syllables that mean the same digit. For example, digit 1 can use we or wa, digit 2 can use te or tu, and digit 5 can use le or lu.
The e, a, i, and u columns show the nanpa-linja-n glyphs for the supporting vowel used in some digit syllables.
For ni, na, and nu, the supporting consonant is represented in nanpa-linja-n by the sitelen pona glyph nena.
The large glyph column shows the main sitelen pona glyph used for that digit.
The small glyph row shows the small supporting glyph associated with each vowel column.
In relaxed mode, for example, we will accept Nemun, as well as Nemen, to represent the number 7.
Relaxed mode is preferred because it allows some digits to be represented using more natural syllables.

How is 125 written as a nanpa-linja-n proper name?

Every nanpa-linja-n proper name for a number begins with Ne- and ends with -n. Each decimal digit maps to a unique Toki Pona Latin letter, which is expressed in the proper name using a designated syllable.

Using the relaxed mapping described above:

1 → w → wa
2 → t → tu
5 → l → lu

These syllables are concatenated between the initial Ne- and the final -n:

Ne + wa + tu + lu + n → Newatulun

Therefore, the nanpa-linja-n proper name for 125 is Newatulun.

As an experimental alternative, a decimal nanpa-linja-n proper name can begin with the separate word Nanpa instead of using the traditional Ne- opening. The decimal digit syllables themselves do not change.

For example, the decimal number 125 has the traditional proper name Newatulun. In the alternative notation it is written as Nanpa Watulun.

In sitelen pona, this alternative decimal form is distinguished by a colon immediately after the opening nanpa glyph. The closing nanpa glyph is unchanged.

decimal	traditional proper name	alternative proper name	full cartouche	abbreviated cartouche
`125`	`Newatulun`	`Nanpa Watulun`	󱦐󱤽󱦝󱥳󱤂󱥮󱥰󱤭󱥰󱤽󱦑	󱦐󱤽󱦝󱥳󱥮󱤭󱤽󱦑

Cartouche source forms for the example above are [nanpa : wan ala tu uta luka uta nanpa] for the full form and [nanpa : wan tu luka nanpa] for the abbreviated form.

Pronunciation note: In this experimental notation, Nanpa may be pronounced as two clearly separated syllables, Nan-pa, to help distinguish the numeric opening marker from the ordinary Toki Pona word nanpa when listening.

Hexadecimal is a base-16 number system. It uses the digits 0–9 and the letters A–F. To enter a hexadecimal value, begin it with #, for example #AF or #C0FFEE. Hex digits 0–9 use the existing nanpa-linja-n digit glyphs shown above; A–F add six hexadecimal digit combinations.

What is hexadecimal useful for?

Colors — for example #FF0000 for red.
IPv4 addresses — for example 192.168.1.1 can be written in hexadecimal as C0.A8.01.01; IPv6 addresses use hexadecimal directly.
Unicode code points — for example U+F193D.
Computer values — hexadecimal is a compact way to write many numeric values used by software and computers.

The six additional hexadecimal digits use the following syllables and sitelen pona glyphs. These arbitrary identifier syllables were chosen to avoid overlapping with the existing syllables for decimal digits 0–9. Because B, C, D, and F are not letters in the Toki Pona alphabet, there is no straightforward one-to-one way to map the hexadecimal letters directly. Their initial consonants—j, l, m, p, s, and t—are therefore assigned in this alphabetical order to the hexadecimal digits A, B, C, D, E, and F, respectively. Most use the vowel a; si is used for E because sa already occurs in Nasa, the hexadecimal opening marker:

hex digit	syllable	large glyph	supporting glyph	sitelen glyphs	abbreviated
A	ja	jan	ala	󱤑󱤂	󱤑
B	la	lawa	ala	󱤤󱤂	󱤤
C	ma	ma	ala	󱤰󱤂	󱤰
D	pa	pakala	ala	󱥈󱤂	󱥈
E	si	sike	ike	󱥜󱤍	󱥜
F	ta	tan	ala	󱥧󱤂	󱥧

Hexadecimal proper names begin with Nasa. Hex cartouches use nasa at the beginning and end, with a colon after the opening nasa, so they are visually distinct from decimal nanpa-linja-n cartouches.

Longer hexadecimal values and separated hexadecimal groups use these supporting forms:

use	proper-name form	glyph sequence	sitelen glyphs	abbreviated	audio
automatic grouping	-n Eke	nena e kule e	󱥀 󱤉 󱤞 󱤉	󱤞
separator with no numeric value	-n Ene	nena e nena e	󱥀 󱤉 󱥀 󱤉	󱤉

For example, #FEDCBA uses automatic grouping between FE, DC and BA without giving that separator a numeric value. Its proper-name form is Nasa Tasin Eke Paman Eke Lajan . This is useful for separating RGB hex encodings.

Similarly, #FE:DC:BA uses the separator between FE, DC and BA without giving that separator a numeric value. Its proper-name form is Nasa Tasin Ene Paman Ene Lajan .

Pronunciation note: In hexadecimal notation, Nasa may be pronounced as two clearly separated syllables, Na-sa, to help distinguish the hexadecimal opening marker from the ordinary Toki Pona word nasa when listening.

The decimal number renderer can render any decimal number and produce an audio pronunciation. The encoding of decimal points and other numeric punctuation, together with the strict and relaxed digit mappings, is explained with examples on this page and in detail in the nanpa-linja-n main documentation .
