#109 Ability to swap operands
Thanks very much for providing this s/w and for keeping this project alive.
I'd like the ability to be able to swap operands - it really speeds things up when using it as a basic calculator.
E.g.
When calculating say
2.21
------------
1 - 3/(5.11*2)
I would like to enter:
5.11*2
/3 x<->y (swap)
-1 Exe x<->y (swap)
/2.21 x-y (swap) Exe
3.128
The 'swap' would exchange the answer with the pending operation.
I recently used an older electronic calulator as my palm wasnt around and realised how much I used to use this function.
Without that ability I find myself overusing parenthesis.
E.g. in the above example
2.21/(1-(3/(5.11*2))) Exe - whoops, did I miss a bracket?
(I know the last one around the multiplication is redundant in this example, but you get the idea).
Anyway, I miss it. If you are looking for screen space I suggest removing the 'delete previous character' button - that, and the forward and back buttons never seemed much use for a device where you can position the cursor by tapping the screen. I'm not saying do away with the forward/back/delete function for devices that have hard keys, just that in my opinion they're not of much use on the screen since a back or forward stroke is so easy.
Thanks again.
