approx(Ans) oddity

1. reset the calc (On+Apps+Esc)
2. go into CAS mode and verify the stack is empty (don't add anything to it)
3. go back to Home and do approx(Ans)
   

and you still get 6. This is the definite bug - both stacks were empty.

Ans gives the result of the last calculation, which is not necessarily the value at the bottom on the history.

For example, enter the following.

Code:

1+2          3
3+4          7
5+6         11

Now press the Del button until you only have

Code:

1+2          3

If you now use Ans, it will return 11, not 3, since 11 was the last calculated result.

Code:

1+2          3
Ans          11

Then there's the matter of clearing the memory. It seems that clearing the memory resets Home Ans to 0 but CAS Ans seems to survive the memory clear. This might actually be a bug.
