Bibi-binary

The Bibi-binary system for numeric notation is a <a href="/facts/Hexadecimal/02ohQW22">hexadecimal</a> numeral system first described in 1968 by singer/mathematician <a href="/facts/Boby_Lapointe/lJ8K1faX">Robert "Boby" Lapointe</a> (1922–1972). At the time, it attracted the attention of <a href="/facts/Andr%25C3%25A9_Lichnerowicz/4AlCVKAP">André Lichnerowicz</a>, then engaged in studies at the <a href="/facts/University_of_Lyon/m4abX7zj">University of Lyon</a>. 
The notational system directly and logically encodes the binary representations of the digits in a hexadecimal (base sixteen) numeral. In place of the Arabic numerals 0–9 and letters A–F currently used in writing hexadecimal numerals, it presents sixteen newly devised symbols (thus evading any risk of confusion with the decimal system). The graphical and phonetic conception of these symbols is meant to render the use of the Bibi-binary "language" simple and fast.
The description of the language first appeared in Les Cerveaux non-humains ("Non-human brains"), and the system can also be found in Boby Lapointe by Huguette Long Lapointe.
