Watch out while entering exponential

This calculator app does pretty much what it should, but I encountered an issue where when I was entering exponentials, I have to enter the sign of the exponential after the value. For example if I want to type 1E-3, I have to type 3 before the minus otherwise a 1 automatically appears and I’ll have 1E13. I find this to be rather unusual and for a calculator app such quirks can lead to lots of problems. Hope the dev will fix this and I’ll change my rating.
