Equal sign in calculator keyboard

Hi there, it'd be amazing if you could add an equals sign to the calculator keyboard. I often split costs with people and seeing the amount before saving it would make it easier for me to create another transaction with the same amount. Example: I pay 74.40 so I add an expense to my Food category by entering 74.40/2 but when I save it I can't see what that amount will be. So when I want to add the other transaction to the Debt category I need to enter 74.40/2 again. If I saw that the amount was 37.2 when adding the first expense, I could just enter that when creating the second one. That's how an equals sign could help.

Alternatively, a split cost feature would be great too but I guess that'd be much more work.
