Edit the result by pressing backspace

Problem Statement

I remember, in the old version of windows 10 calculator, when we do a calculation, and press enter and the result appear, with pressing backspace key, it kind of edit the result by deleting the last digit of the result. now it is not in this way, and when a result is shown, nothing happen by pressing backspace key
Example :
6.5 * 12.5
then by press Enter it will show the result :
81.25
and then by pressing backspace 3 times, it will delete .25 and we can use 81 for our next calculation.

I think it is a good feature that can be added to windows 10 calculator.
