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 uses 8 characters: 4 vowels O, A, E, I and 4 consonants H, B, K et D. So it is not exactly a base 4 numeric system, but, depending on the parity (odd/even) it uses a vowel or a consonant. This subtlety supports that it is a base 16 writing (hexadecimal).
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
