Tool to convert bibi-binary numbers. Bibi-binary (or bibinary or bibi) is a numeric system invented by Boby Lapointe in order to represent numbers in letters which pronunciation seems funny.

Each number is converted in base 16 (hexadecimal) and each character is replaced by its BiBi-binary name

0 = HO, 1 = HA, 2 = HE, 3 = HI, 4 = BO, 5 = BA, 6 = BE, 7 = BI, 8 = KO, 9 = KA, a = KE, b = KI, c = DO, d = DA, e = DE, f = DI

Example: 123 in base 10 is written 7b in base 16 and 7 = BI and b = KI so 123 = BIKI

Each group of 2 letters is replaced by its equivalent in base 16.

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

Each number obtained in base 16 is then converted to base 10.

Example: BIKI = 7b in base 16 and equal to 123 in base 10.

Boby Lapointe described BiBi-binary as a short binary code. Citations :

With the binary code, with 4 digits, you get up to 15. With BiBi-binary, you 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.

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 an hexadecimal system.

Binary code is segmented by groups of 2 (from the right side)

Example: 110111001 becomes 01 10 11 10 01

Still from the right, groups are replaced by voyels 00 = O, 01 = A, 10 = E, 11 = I

Then, the next group by consonants 00 = H, 01 = B, 10 = K, 11 = D, and so on alternatively

Example: 01 10 11 10 01 = AKIKA, and complete with 00 = H => HAKIKA

A patent has been set in 1968.
