A google for “iphone calculator bug” will yield a few bugs, but it looks like most of the found bugs have been fixed at this point. And this one a bit less obvious than a truncation or rounding due to display capacity. This is on the current version of the iPhone firmware : 1.1.1

What is 49,999,999.99+.008?? 49,999,999.9980 Right?

Ask your iPhone: Where 49,999,999.99+.008 = 5

This problem exists with any number where the iPhone’s screen capacity for numbers is fully used, for instance: 4999.999999+.0000008 = 5

It seems the calculator does not use sufficient significant figures in calculations.

Not a serious problem since most people don’t need to work with large decimals, and if they do they can just take the TI-89 out of their other pocket.

My point in all this is that there needs to be more stuff to do on the iPhone, because if I’m sitting in class looking for calculator errors it is obviously a boring device (when I don’t need directions, to talk to someone, or to find out where I am supposed to be with the calendar).
