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?
π[sup]2[/sup] = 9.86960440109 in 10.4.11.
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.
