strings are in base two, got it

Wouldn't the answer be "10" in that case?

[–] [email protected] 39 points 4 months ago

yes, if I could do maths

1+1=11 means base 1

[–] [email protected] 5 points 4 months ago (1 children)

How so?

1 11 111 1111 11111 111111

That's base 1. By convention, because it doesn't really fit the pattern of positional number systems as far as I can tell, but it gets called that.

Oh, I get it, was reading as base 2 and confused by that. Essentially Roman numerals without all the fancy shortcuts.

Closer to tally marks without clustering

Who calls it that? Who even uses that enough to have given it a name? Seems completely pointless...

Theoretical computer scientists, historians of mathematics.

I'm not sure where I heard the term exactly, but I know I have multiple times.

Thanks for sharing this, it's quite interesting. I found a Wikipedia article on it: https://en.m.wikipedia.org/wiki/Unary_numeral_system

Apparently, as you did suggest, "base 1" is a name that is used, but is somewhat a misnomer.

The article mentions that Church encoding is a kind of unary notation, which I would not have thought of, but I guess it is.
