In a recent
tip, TUAW reader Dr. Drang told us about a bug he found on the iPhone/iPod touch’s
calculator. According to his research, when you type π × 2 + 5 = into the calculator you get 11.283… (the correct answer). However, when you reverse the
Pi and 2, entering 2 &times π + 5, the answer given is 7.

This error can be demonstrated by entering Pi (3.141592654) manually, instead of using the Pi button — you will get the correct answer each time. Therefore, this error only shows up when you use the Pi button.

So, be sure to read up on this bug from the
tipsters website before you use the calculator for anything too important.

Update: Reader Vineet
writes in the comments to note that this behavior is typical of stack-based calculators and should be considered more of an operator-expectations issue than a true bug.

Thanks for the tip,
Dr. Drang!
