Ok, I don't know if it's just mine or something inherently wrong with the iPhone calculator 
Go into calculator, switch to landscape (scientific) and hit 7^3 (7 cubed)
Now hit the x(root)y key and type 3. This will do the cube root of 343. Now the answer should be 7, but my iPhone shows 7.000000000000002. You can't try it with any integer and it will show an incorrect number if the power (3 in this case) is odd.
Does anyone else get this on the iPhone?
