So, on a Mac, PI + PI = 6 ?

[QUOTE=Sleel]
We’re talking about the Calculator application included in the standard installation of OS X. The scientific functions are hidden by default, but you can toggle between the relatively limited standard calculator, a scientific one, and a programming calculator in the View menu. Unless you’re using this specific application, you’re probably not going to see the error we’re seeing.

Ok, my bad. With the original calculator, I’m getting 6.

Mac OS X 10.4.11 here, and in addition to things mentioned:

Pi + 1=4

Non Mac user, so I can’t check this on my own - but what does π[sup]2[/sup] yield?

Out of curiosity, have you gotten any reply to your bug report yet?

Rats. That’s no fun. I was so hoping it would turn out that π[sup]2[/sup] = 10

Apple has almost, but not quite, made an Radcon math calculator.
