Talk:Negabinary

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 dx...d2d1d0, where dsomething is a digit 0 or 1, would be $$\sum_{n=0}^{x}d_{n}(-2)^{n}$$.
 * -11101100101010101101 would then be 110100101111111100111.
 * I haven't actually looked any of this up anywhere, or heard it anywhere, just seemed likely. &#1603;&#1587;&#1610;&#1662; 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
When at the counting section, the numbers go:

0 1 110 111 100

Is this correct?

Time discrepancy
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?
