On: The Mystery of 355/113

[ColinWright]

It's not actually the difference to pi that matters, it's the "quality" of the approximation, as described in the article. You can always get better approximations by using larger denominators, it's just that some approximations are, given the size of the denominator, unreasonably good.

355/113 is one of those.

True, I didn't do the quality measure they talk of. I was just fascinated by:

"For example, use any scientific calculator to compute cos(355) in radians. The oddball result is due to the freakish closeness of 355/113 to pi."

And wanted to see what else would fit this criteria...
