### Removed definitions

1. (computer science) bit state corresponding to binary digit 0, or FALSE; in a logic gate off or the low state.
2. (mathematics) A Boolean or truth value corresponding to FALSE.

Maybe someone could explain to me how a bit state isn't a binary value, or how Boolean logic isn't a group over disjunction? Davilla 17:24, 29 May 2006 (UTC)

I get your objection, but don't think you're being literal minded enough:
1. Perhaps the subject should include (electrical engineering) since the a bit state in an actual electronic device corresponds to a particular voltage range, usually less than some threshold tolerance. Thus it should also include the synonym low state.
2. In Boolean logic the value 0 is synonymous with FALSE which is not the case with any other algebraic structure, for example, the integers modulus 2. Wikipedia has both Boolean logic and Boolean algebra separately. Most computer languages recognize Boolean truth operations, but not more abstract algebraic operations. N.B. the capitalization in FALSE is significant.
Can we agree to restore these with amendments/understandings?

Finally, the Boolean domain cannot be used for numbering. In particular there is no representaion for 2 which is distinguishable from 0, that is there is no successor function in a Boolean algebra. Rmo13 03:14, 30 August 2006 (UTC)

Uh, how is this a different sense? 72.177.113.91 08:58, 12 March 2009 (UTC)

Delete sense with extreme prejudice, before we end up with separate "senses" for every font in existence. -- Visviva 15:45, 12 March 2009 (UTC)
User:Rodasmith added [this] item as an alternative form, since some of the digitized numerals are considerably distorted and stylized. Someone else later moved it to a sense. User:Rodasmith made this addition to all of the Arabic numerals. —Stephen 21:54, 12 March 2009 (UTC)
For a symbol, we could include an illustration showing its historical development, or its different expressions (manuscript, blackletter, uncial, but I'd consider LED display, which simulates a sans-serif font, as a low priority). But this would be an encyclopedic supplement, and not part of our core dictionary information about the term. Michael Z. 2009-03-13 14:52 z

Deleted with prejudicial extremedom. Would be interesting to have a library of glyphs though. 63.95.64.254 03:05, 17 March 2009 (UTC)

## Full-width digits

Where does belong? They are used in Japanese (more consistently) and Chinese. Anatoli 05:40, 21 August 2009 (UTC)

I'll bring up in GP. --Bequw¢τ 00:19, 22 August 2009 (UTC)
Thanks. I have replied there and created Japanese entries for full-width numerals. If they are used in other languages or end up being translingual, this can added later. Anatoli 10:58, 22 August 2009 (UTC)
