Base 3 even/odd equivalent?

Modulus.

x % 3 (read as "x mod three") is the remainder after dividing by 3. So:
if x % 3 = 1, it's what you call odd1.
if x % 3 = 2, it's what you call odd2.
if x % 3 = 0, it's what you call 3ven.

Okay :)

But those aren't "words" really. "Percentthreeequalszero" doesn't really roll off the tongue the way Even and 3ven do.

By any chance are you a CS major?

kill yourself

>>8612845

Almost was, but didn't.

>>8612848

Is it okay if I just kill you instead?

In your base three system, are the first three numbers 1, 2, 3 or 0, 1, 2?

> percent
it's called mod, he literally says it in the second line.

>>8612856
0,1,2

>>8612818
holy crap I was just thinking about this two days ago. I like your names.

odd = 1 mod 3
nod = -1 mod 3
even = 0 mod 3

>>8612818
Even is short for "divisible by two"
Odd is short for "not divisible by two"

There is nothing stopping you from coming up with similar words for three, except that it wouldn't be as useful unless as you said you're in base 3 or doing something weird. Really, the correct way to deal with it is to just use the long form and throw out terms like Even and Odd.

The general term is "n-smooth" numbers, so any number divisible by 3 would be 3-smooth.

>tfw you realize we should have used base 12, because it's 2,3,4,6-smooth, but it's too late to every change :(

>>8612973

Aha! Okay. 3-smooth.

I think base 10 is better because division by 3 or 4 isn't so difficult in base 10, whereas division by 5 would be a total pain in base 12.

1/3 = .333... in decimal.
1/4 = .25 in decimal.
1/5 = 0.249724972497... in base 12.


Apperently Roman numerals used base 12 for fractions. They chose to drop base 12 when decimal came in.

I wasn't really thinking about being IN base 3. But there are lots of real life situations where people say "even" and "odd", and I thought that if there was an analogous word for multiples of 3, it might be useful.

There is a word called throdd.

In your base ten system, are the first ten numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or 0, 1, 2, 3, 4, 5, 6, 7, 8, 9?
