Kaktovik numbers or numerals (or IΓ±upiaq numerals) are a positional base 20 numeral system used by Inuit/Inupiat peoples in Alaska and Canada.
Start by converting the number to base 20 (see explanations on converting to base N).
Then replace each number (from 0 to 19) with the corresponding Kaktovik symbol:
Decimal Value | Unicode | Image |
---|---|---|
0 | π | ![]() |
1 | π | ![]() |
2 | π | ![]() |
3 | π | ![]() |
4 | π | ![]() |
5 | π | ![]() |
6 | π | ![]() |
7 | π | ![]() |
8 | π | ![]() |
9 | π | ![]() |
10 | π | ![]() |
11 | π | ![]() |
12 | π | ![]() |
13 | π | ![]() |
14 | π | ![]() |
15 | π | ![]() |
16 | π | ![]() |
17 | π | ![]() |
18 | π | ![]() |
19 | π | ![]() |
To write a Kaktovik number in classic decimal representation, locate each symbol and replace it with the associated number (between 0 and 19) so as to obtain a positional numeration in base 20 which will still have to be converted into base 10 (decimal).
Decimal writing uses the dot . to separate the integer part and the decimal part.
As the writing is in base 20, the first digit after the decimal has the unit $ 20^{β1} = 0.05 $, the second $ 20^{β2} = 0.0025 $ etc.
The digits of the Kaktovik numeral consist of 1 to 5 vertical bars (forming W) and 1 to 5 horizontal bars (forming α¬)
Any references to Inuit, IΓ±upiats or even Inuktitut are clues.
The count was developed in 1994 in Kaktovik, a town in Alaska by a group of students.
