Re^2: [OT] math fulguration

> I have no idea how broadly it is known.

Pretty much, what Salva pointed out is discussed at university in CS in the context of numeral systems to basis n, before introducing binary system.

By intuition I'd say it's also connected to some school math, like the theorem that every periodic fraction can be expressed in the form of

n+(m/9...9) with n,m in N

  DB<3> p 3+7834/9999
3.78347834783478

This works in any number system.

What I learned was the word "fulguration". ;-)

... learned ... the word "fulguration". Related: fulgurite. Also: Is there a link to a definition of "fulguration" in a mathematical context? I seem to see it only in the medical context of "radiofrequency ablation" or coagulation. Give a man a fish: `<%-{-{-{-<`	[reply] [d/l]

I think Discipulus meant "enlightenment" in the spiritual sense, the bodhi or satori. `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l]

Looks more like an "obfuscation" to me. Cheers, Rob	[reply]

"fulguration" I don't recall that word at all from any crufty discussion in number theory or logic design with the faculties of a handful of american universities where I might have been a fly on the wall. Others' mileage may vary. The usage that is common for us of a certain age is the one that is a synonym for 'ablation'.	[reply]
