Feature description

Memory operator -- stores current value in memory or recalls value stored in memory

Multiple ways this could be implemented...

Implementation #1
· button: M or clipboard
· Long press button →store value
· Tap button → recall value
· M could be an outline when empty and filled when it has a value

Implementation #2:
· button: M or {into box and out of box}
· If current input is a value →store value
· If current input is an operator or is empty →recall value

Implementation #3:
· button: M+
· tap button →add value to memory
· long press button →recall value and clear

Additional thoughts
· The memory button could replace the largely broken percent button
· the memory could simply be the clipboard. If so, the icon could change based on current behavior -- and arrow pointing in to the clipboard to copy and and arrow pointing out to paste (if implementation #2 is used)

Why do you want this feature?

Allows for complex calculations without implementing stuff like equations and parenthesis...

Additional information

This relatively simple feature would make the calculator significantly more powerful. Use examples:

Pythagorean calculation: 12*12 = store clear 13*13 + recall = store clear sqrt recall =

(1+2)*(3+4)/5 → 1+2 = store clear 3+4=*recall=/5=
