An international auxiliary language called Ygyde
has two optional number systems: decimal and octal.
Octal glyphs are shaped like binary numbers, so
they are very easy to memorize. Another good
thing about Ygyde's glyphs is a very big full stop.

Duodecimal system (base 12) was used for some purposes by the Romans.
Hexadecimal system  (base 16) is used by some modern computer software.
Octal system (base 8) was used by some old computers.
Vigesimal system (base 20) was used by the Mayans.
Sexagesimal system (base 60) was used by the Babylonians.

To the best of my knowledge the best number systems
are octal and duodecimal. Octal has simpler multiplication
table than decimal (base 10) and its numbers are almost as short.
Duodecimal has only one advantage: non-recurring point fractions.
