Answers to Questions (FAQ)
What is Bibi-binary? (Definition)
Bibi-binary is a number representation system invented by Robert Lapointe in 1968.
It is a base-16 (hexadecimal) notation in which each digit (from 0 to 15) is replaced by a syllable composed of a consonant and a vowel.
This system allows numbers to be transformed into sequences of pronounceable syllables, with both a playful and mnemonic purpose.
How to convert to Bibi-binary code?
To convert a decimal number to Bibi-binary, start by converting the number to base $ 16 $ (hexadecimal) and replace each hexadecimal digit with its corresponding syllable.
| Hexa | Bibi | Hexa | Bibi | Hexa | Bibi | Hexa | Bibi |
|---|---|---|---|---|---|---|---|
| 0 | HO | 4 | BO | 8 | KO | c | DO |
| 1 | HA | 5 | BA | 9 | KA | d | DA |
| 2 | HE | 6 | BE | a | KE | e | DE |
| 3 | HI | 7 | BI | b | KI | f | DI |
Example: $ 123_{(10)} $ is written $ 7b_{(16)} $ in hexadecimal, as $ 7 $ corresponds to BI and $ b $ corresponds to KI, then: $ 123 $ is written BIKI in bibibinary.
How to convert/decrypt the Bibi-binary code?
Each 2-letter bibi-binary group is replaced by its base-16 equivalent.
To convert a bibi-binary word to a decimal number, divide it into 2-letter groups, replace each group with its hexadecimal equivalent, and convert the resulting number from base $ 16 $ to base $ 10 $.
Here is the inverse lookup table:
| Bibi | Hexa | Bibi | Hexa |
|---|---|---|---|
| HO | 0 | HA | 1 |
| HE | 2 | HI | 3 |
| BO | 4 | BA | 5 |
| BE | 6 | BI | 7 |
| KO | 8 | KA | 9 |
| KE | a | KI | b |
| DO | c | DA | d |
| DE | e | DI | f |
Example: DEKODE is broken down into DE,KO,DE, which is $ e8e_{(16)} $ in base 16 and therefore $ 3726_{(10)} $ in decimal
How to recognize Bibi-binary code?
The message consists only of two-letter syllables: 'de, da, do, di, be, ba, bo, bi, ke, ka, ko, ki, he, ha, ho, hi'
The message is composed of a maximum of the four consonants 'D, B, K, H' and the four vowels 'E, A, O, I'
What is Bibi-binary notation?
Bibi-binary also associates each value with a graphic symbol. These symbols are constructed from the 4-bit binary representation:
Bits with a value of $ 1 $ correspond to angles or endpoints, while bits with a value of $ 0 $ correspond to curves.

Why the name Bibi-binary?
Boby Lapointe described BiBi-binary as a short binary code. Citations (translated):
With the binary code, with 4 digits, get up to 15. With BiBi-binary, get up to 15 … with 2 letters. […] In argot bibi means me, my name is Boby and my children call me bibi so it is fun to call this system Bibi. […] Binary is a base 2 system, bibinary is a base 4 system, bibi-binary is a base 16 system.
Base 4 or Base 16 for Bibi-binary?
Bibi-binary is a base-$ 16 $ system. The confusion with a base-$ 4 $ system arises from the fact that each syllable is composed of a consonant (4 possibilities: H, B, K, D) and a vowel (4 possibilities: O, A, E, I). This gives $ 4 Ă— 4 = 16 $ possible combinations, corresponding exactly to the 16 digits of the base-$ 16 $ system.
Some would say it's a base-4 system alternating digits/letters depending on whether the position is even or odd.
How to convert binary to Bibi-binary?
Segment the binary code in groups of 2 (from the right)
Example: 110111001 becomes '01, 10,11,10,01 '
Always starting from the right, replace the first group with vowels then the next group with consonants and so on alternately according to the table:
| 00 | O | H |
| 01 | A | B |
| 10 | E | K |
| 11 | I | D |
Example: '01, 10,11,10,01 becomes AKIKA', if the number of letters is not even, complete with an initial H or HAKIKA
When was Bibi-binary code invented?
A patent FR1569028 has been set in 1968 by Robert Lapointe, known as Boby Lapointe.
