Unless you can figure out *why* the value has a particular formula,
using a formula rather than a number isn't really gaining you anything.
(Although, frankly, you have a number with 8 decimal places. That's 8
orders of magnitude covered, which is already pretty accurate.)

I ordered stamps from Zazzle that read "Place Stamp Here".

You're aware that's the same thing as sqrt(3)/6, right?

Not unless he included way too many incorrect digits at the end.

So sqrt(1/12) is it then!
As a side note, the only equation I was able to find which fit the last
digit of "9" which you included was:
2 - 1/(gamma[19/24]^2 * ln[ChampernowneNumber[10]] * zeta[3])
(formatted so you can type it into Wolfram Alpha)
Which clearly is highly unlikely to be what your number came from, so it
looks like Vincent's hypothesis is pretty surely the correct one.

Note that tand(60) = sqrt(3).

That would be the distance between the centroid of an equilateral
triangle and any of its edges.
Could that possibly be a fit?

No kidding! I *said* I was looking for _trigonometric_ functions, which
sqrt(3) isn't.
Anyway, I was able to determine where in the scene the value was coming
from, so the problem is resolved.

0.28867519 seems perty close to Gamma/2 as well.
