Programmer? Or maybe a mathematician's clock? Maxwell Smart and agent 999's clock?

Very cool clock Yardman!
Here's another programmer's clock:

can anyone explain what the ones for 7 and 9 are?

EDIT: Is that .999999 supposed to be one?I don't see why so many people think that....

Here are several proofs of that fact. If you are like me at least one of them will convince you Razz

I was looking at that page after I posted, I still don't believe .99999 is 1....and I don't care what anyone says... Smile

Edit:
that one explanation labeled "digit manipulation" is just silly, it tries to show x=.¯9 so 10x=9.¯9 then 10x-x=9 so 9x=9,thus x=1...but .999.... to any amount times 9 is 8.999.......



WOOOOO, my 2^7'th post!


EDIT2:

It's just as bad as people believing 9 divided by 9 is .¯9

The proof with fractions wasn't convincing enough? I remember that it was that proof that convinced me of the non uniqueness of the decimal (and other integer bases) number representation, which, BTW, I've learnt all this less than a year ago Embarassed

Sorry, i probably missed most of this thing, and my theoretical math knowledge is very poor (even though many people told my me my theoretical math talents are high),but... why did you think that decimal system was unique, in first place?

I don't see so much difference between numeric base with ********** (10) symbols, and numeric base with ** (2) symbols, or base with *** (3) symbols, or base with ******* (7) symbols, etc...

You should have quoted me up to the comma Wink

Anyway, what I've tried to say was that in a given integer base number representation system, a given number does not have an unique representation. Before knowing that a0.(9) is a0+1, I though that every number had a SINGLE representation on a given representation system, not that every number has the very same representation in any system (is this what you though I was thinking?)

Some cultures only have three numbers: 0, 1 and lots. I think we should teach our computers just these three numbers only.

With parentheses meaning repeating decimals:
0.(1)=1/9
0.(2)=2/9
0.(3)=3/9
0.(4)=4/9
0.(5)=5/9
0.(6)=6/9
0.(7)=7/9
0.(8)=8/9
0.(9)=9/9

I have lived a fortunate life: no one ever has accused me of possessing any kind of theoretical understanding of any subject.

I realize how unsophisticated I am, when looking at this clock, for I cannot decipher the numeral five.

Square root of 9, ok, got that: it is 3.
Now, comes an exclamation mark. I have no idea what that represents. In C programming, I believe, and may be in error, as usual, that this symbol corresponds to the Boolean "NOT" function. Perhaps here there is some other convention, I am simply unaware of.
Of course, even I can recognize that 9/9 = 1. So, it becomes 3 ! - 1. How do we obtain five from that? Oh, you mean that the Exclamation mark is also a symbol used to represent factorial! Ah, ok, got it.
(3 * 2 * 1) - 1. Wow. What a chore. Holy cow.

not sure if binary clock (pointed by HyperVista) is good at darkness Wink
+++ unless blinking right bottom point is enough good ruler
2++ it would be better if zero also were indicated, say, 0 - yellow (darker), 1 - blue (and brighter)

that clock i made at 1986, when i was a schoolboy:

when i live in the students hostel, it was a problem when cocrouch entered clock and sitting somewhere at indicator, damaging displayed number look from a distance Razz

9 raised to the 9th power, then find the 9th root.
you'll get a 9 Very Happy

That is an accusation, something bad for you? Laughing

AFAIK that's the symbol used in math, so at least you should know the standards before considering it a chore Wink
