Talk:Boolean values

Python twice?

It's already been noted. a merge is in the works. --Mwn3d 20:20, 10 July 2009 (UTC)

Sorry about the wait. All done. --Paddy3118 21:12, 10 July 2009 (UTC)

Rename page?

This page only deals with the two-valued boolean algebra.

This leaves out some important history and the full scope of what the word "Boolean" means. This is a distressingly common practice.

See, for example:

http://sumon3get.hubpages.com/hub/Basic-Concept-And-History-Of-Boolean-Algebra

http://mathworld.wolfram.com/BooleanAlgebra.html

Remedies might include:

1. A new page title that somehow incorporates the phrase "two valued".

2. A new Rosetta code task which treats some other subset of boolean values. For example, here's a table the boolean operation which corresponds to "logical and" on the integers 0 through 3:

<lang J> *. table i. 4 ┌──┬───────┐ │*.│0 1 2 3│ ├──┼───────┤ │0 │0 0 0 0│ │1 │0 1 2 3│ │2 │0 2 2 6│ │3 │0 3 6 3│ └──┴───────┘</lang>

(this operation is "least common multiple",).

And here's the boolean operation which corresponds to "logical or" (greatest common divisor) on these integers:

<lang J> +. table i. 4 ┌──┬───────┐ │+.│0 1 2 3│ ├──┼───────┤ │0 │0 1 2 3│ │1 │1 1 1 1│ │2 │2 1 2 1│ │3 │3 1 1 3│ └──┴───────┘</lang>

Note also that "logical not" is not a boolean operation in and of itself. --Rdm 13:40, 30 April 2012 (UTC)
