Base ten is called “decimal”; what's the name of numbers in base 15?

Good afternoon all, I was wondering is there a table of names for the base x of numbers?

For example, I know that numbers in base 10 are called "decimal", those in base 2 are called "binary", base 16 is called "hexadecimal", but what will be the name for those in base 9, or base 15 ?

it has no real name you could expand the latin (or was it greek?) to other numbers (pentadecimal) but I doubt it will catch on, no-one uses base 15 or base 9 enough for it to get a name

I have heard the term quindecimal but looking in Google now shows that (although it can be used for base 15) it is primarily used for a certain 15-note musical scale.

About typography: please omit the hyphen after "base"; in that position it could be taken (as I did) for a minus sign. Positional number systems with negative bases do exist!

Your title should say "base 2" or "base two" in reference to binary, not "base 10" (which ordinarily means "base ten"); i.e., "base 10" is not ordinarily called "binary".

Nonary and pentadecimal respectively.

You might also be interested in the Wikipedia articles that give the names for n-ary bases and the article on radix, which is another name for 'base'.

There's a convention that when new words are coined, one doesn't mix Latin with Greek. This is sometimes violated, e.g., in "automobile," where "auto-" is Greek but "-mobile" is Latin. But since GEdgar points out that quindecimal does have some currency, that would be a reason to prefer quindecimal rather than pentadecimal. Here is some information about Greek and Latin number prefixes: en.wikipedia.org/wiki/Number_prefix Google ngram viewer books.google.com/ngrams shows zero hits for both words in books since 1800, which suggests that there simply isn't a commonly accepted word.

@BenCrowell I'd err slightly in the other direction, for two reasons: (a) 'pentadecimal' is consistent with 'hexadecimal' which also mixes Greek and Latin, and (b) a Google verbatim search shows five times more hits for 'pentadecimal' than for 'quindecimal'. But I agree that there is little consensus, and for that reason it probably doesn't matter which you use. As an aside, my favourite example of a mixed Greek-Latin root is 'television' :)
