Transcript:

Cueball: Hey, check it out: e^π^−π is 19.999099979. That's weird.
Black Hat: Yeah. That's how I got kicked out of the ACM in college.
Cueball: ...what?

Black Hat: During a competition, I told the programmers on our team that e^π^−π was a standard test of floating-point handlers -- it would come out to 20 unless they had rounding errors.

Cueball: That's awful.
Black Hat: Yeah, they dug through half their algorithms looking for the bug before they figured it out.

Also, I hear the 4th root of (9^2^ + 19^2^/22) is pi.

My kid is studying physics in university, and she comes home and tells me physics anecdotes which I don't understand, so I always reply "That's Numberwang!".

So I can see these types of conversations happening between math and programming types.

That is a truly excellent response! Anyone in this thread who hasn't seen "That Mitchell & Webb Look" should go watch it - you're in for a treat.
