      I get the same answer in Standard or Scientific (1125899906842624). Do you get something different? (1.33333-->to infinity * 3 = 4)

          There's a standard mode? Wow... That's retro... :-D

            Since this message is being downvoted into death... 8.) Press = 52 times for a whole number in Standard Mode, or a fraction in Scientific mode. The * 3 at the end was to display the fact that Standard Mode cuts off extra decimals which are generally vitally important, leading to a comical fact of "x.3 * 3 = 3x + 1" (Assuming x > 0 of course)

              So what? If you needed that kind of precision you would normally be using scientific mode anyway.

                If you want Mathematica, use Mathematica.

                  You actually did this?

                      It wouldn't have mattered, the math was still correct, it just wasn't displaying the entire infinitely long decimal. Unless of course your satellite relied on the display of the calculator for it's solution. ;P

                        That is fifty-five presses too many. best, Bill

                        It keeps me humble to think there's more bacteria in my gut than neurons in my brain, and that twenty trillion neutrinos pass through one hand a second, and that the average mattress contains 20 million bedbugs each of whom shits once per hour.
