Talk:0 (number)

"which represents itself" - is that correct or do I just misunderstand it? I've always learnt that 1 is the identity number. --Tom Vogt 07:03, 31 January 2008 (CST)

I don't know what the intended meaning is. I have deleted the offending sentence and reformulated the rest. -- Jitse Niesen 09:30, 31 January 2008 (CST)

Is binary a place holder/value system? --Robert W King 09:35, 31 January 2008 (CST)

I think place-value system means the same as what I would call positional system. In that case, binary, octal, decimal and hexadecimal are all place-value systems. -- Jitse Niesen 11:26, 31 January 2008 (CST)

Although binary uses "1" and "0", those are "On" and "Off" states, are they still positional/place-value? --Robert W King 11:30, 31 January 2008 (CST)

Yes, 1011 stands for 1*2^0 + 1*2^1 + 0*2^2 + 1*2^3 in the same way as 1026 stands for 6*10^0 + 2*10^1 + 0*10^2 + 1*10^3--Paul Wormer 11:42, 31 January 2008 (CST)
