Spotlight calculator pie
Spotlight has a useful calculator good for simple arithmetic. It will also return several constants, including pi and e.

Perhaps as a joke, it will also return pie (pi*e) = 8.5397342227 from the Calculator application.

[crarko adds: OK, I admit it's not much of a hint, but I do appreciate the fact that somebody at Apple has a sense of mathematical humor. And I'm posting several small things from the queue today. Happy December 1st.]

I don't think it's a joke. If you type "epi," it also works. It looks like the Spotlight calculator does implicit multiplication automatically, including directly between named constants (this is the first calculator I've ever seen that does this).

It will also calculate "pipi", although it wasn't the first result on my spotlight …
There's also "pieeee" and so on …

But still interesting to see spotlight calculator implicitly assumes multiplication. So, also "2pi" or "sin(2pi)" will work.

In 10.5.8 work pi+-*/, not e.

Well, it works in Snow Leopard.

But be careful with e, as it can have different meanings; for example, 1e2=100 (1*10*10) is not equal to e2 (e*2).

@Perhaps as a joke

What's the joke?

3.14159 * 2.71828 gives the same answer as Apple's calculator (within the round error).

And predictably, plugging pi*e into Google's search box yields the same.

It's buggy, so don't use it instead of a real calculator.

Try 2pi-pi2, which should be 2*pi - pi*2 = 0. It interprets it as 2*(pi - (pi*2)) = -2*pi. It gives the right answer for 2*pi-pi*2.
