Symbol

[ImLostAgain]

Absolutely no idea where to put this.

Has anybody any idea what a circle with a forward slash running through it means.
I was reading something and it said " D = (symbol)". It was just black and white.
Hope that's enough to go on.

It's a Continental way of distinguishing zero from the capital letter O. Computer programmers and other people who prepared written data for punching into computers in the 60's and 70's picked it up, along with the corresponding ways of distinguishing Z from 2 and 7 from 1.

Could be a zero or perhaps indicating diameter.

Having re read it is diameter.

[ImLostAgain]

Thanks both. The O answer would seem to fit in this case.

[EcclesCake]

No, it's D for diameter.

[ImLostAgain]

Ok when I get the chance I'll re-read the thing again. It was a sort of multi quiz thing (if memory serves) and each clue leads on to another. Put all together and a result is achieved.
Like I say, a re-read is required.
Thanks again.

If it looks a bit like a gk phi
then it could be the null set ( the set without any elements in it ) and this is NOT the set with zero in it
clearly this has one element in it: zero and looks like [0]

presumably you werent reading Goldilocks and the three bears .....

Eccles has my vote...commonly used for dimension of "diameter".

When I first started in computing and needed to make sure the instructions were clear for those who had to punch the holes into the tape, the cards would be filled out with a vertical line through the O to be a zero. Phi type symbol. Φ Still use it sometimes now, old habits die hard. Never heard if it being horizontal though.

The mention of forward slash made me think diameter.

I recall seeing that symbol on architectural drawings some time ago, and I asked the site supervisor what it meant: sure enough, he said "diameter".

[Mamyalynne]

Any more slashes and I'll have to get the mop.

[EcclesCake]

You've nothing to fear from me Mamya, I've got my tena's!

It will depend entirely on the context in which it was used as it means both zero and diameter.
We used this symbol in the Police to differentiate between 0 and O, therefore it could be a value assigned to D (D =0, X=3 etc)
It appears on the front of a camera lens to indicate what size filters it takes (symbol = 52mm) ie the lens takes 52mm diameter filters (Diameter is symbol)

[EcclesCake]

Shoota, that is why on re reading that D = 'symbol' that I concluded that it was diameter being referred to.

Gawd you people are clever!!! I've just come in from watching Brazil getting de-constructed by Germany so I'll have to take time to re-read it again and also go through your links....but it wont be tonight.
Thanks for your time.

I live on the Continent and have never seen a slashed zero, we cross our seven's though.
