# Bibi-binary Code

## Bibi-binary Code Encoder/Converter

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.

### How to convert in Bibi-binary code?

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

### How to convert/decrypt the Bibi-binary code?

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.

### How to recognize Bibi-binary code?

The message is only composed of syllables de,da,do,di,be,ba,bo,bi,ke,ka,ko,ki,he,ha,ho,hi.

### What is Bibi-binary notation?

### Why the name Bibi-binary?

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.

### 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 an hexadecimal system.

### How to convert binary to Bibi-binary?

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

### When Bibi-binary code have been invented ?

A patent has been set in 1968.
