I see what you are saying, though . . . if you get an exact answer, you should be able to get the approximation.

Sometimes it hangs and sometimes it doesn't. It does take a long time, but I've had it hang (to where [On][Symb] did nothing) and using the reset hole was the only way to get the calc back into working order.
