how are negative and positive numbers represented?

(--Tarquin)

- I assume the value of the digit n, counting from digit 0 on the right, is (-2)
^{n}, and guessing that each digit can be 0 or 1. (If each digit can be 0 or -1, it wouldn't make much difference.) - So the number d
_{x}...d_{2}d_{1}d_{0}, where d_{something}is a digit 0 or 1, would be . - -11101100101010101101 would then be 110100101111111100111.
- I haven't actually looked any of this up anywhere, or heard it anywhere, just seemed likely. كسيپ Cyp 17:29 2 Jun 2003 (UTC)

- That is correct according to MathWorld: http://mathworld.wolfram.com/Negabinary.html --Cessen 07:46, 6 May 2005 (UTC)

## Counting[edit]

When at the counting section, the numbers go:

0 1 110 111 100

Is this correct?

## Time discrepancy[edit]

The Polish-named guy independently discovered it 9 years after two Polish computers were designed to use it. Sounds unlikely. Can someone re-research that please?
