CWick Contest #4: The Tau Problem

u/p2 March 03, 2017, 11:51:22 AM

hehe force the tau beliefers to use a pi formula

u/kotu March 03, 2017, 12:01:03 PM

const double PI_DIV_2 = 1.5707963267948966192313216916398;
const double PI = 3.1415926535897932384626433832795;
const double PI_MUL_2 = 6.283185307179586476925286766559;

the ultimate solution!!

You mean ETA, PI, and TAU.

er, no

lol

u/p2 March 03, 2017, 12:24:59 PM

why isn't there nyone backing ETA as the one true constant...?

There is...

...but these people are rare to find, and the idea of eta being the "true" circle constant largely hinges on the argument that the right angle should be the fundamental unit, instead of the area of a unit circle with pi, or the circumference of a unit circle with tau. Which, as you know, I think is silly.

Reminder that the contest ends tonight. I won't mind if anyone's late due to timezones or anything, but make sure your entry is submitted by email before I process the results. I'll show the results tomorrow on Pi (or Tau/2) Day live on YouTube or Twitch, stay tuned.

Actually, the "sometimes missing leading 0's" is not a mistake. My program basically took numbers in base 100 and displayed them, and the numbers in question were digits of tau. Leading 0's on numbers seemed to be impossible to display, so I just trailed the previous numbers with 0 and then continued. All the digits are correct and in the right order.

For example:

8125724179
972560696
5068423413

If I'd have done that "optimally" and made 9725606965 the second line, the third line would have a leading 0 (which I couldn't figure out how to display).

Hope it makes sense now!
