Differences From the Hardware 1-Step
====================================

While the app closely duplicates our SK-6256 hardware calculator, there are a few differences. The main ones are:

* The app does not offer an option of AOS mode

* The app uses scientific notation to display very large and small numbers instead of overflowing

* The app has higher internal precision

* The app does not wait for the = key for Decimal/Fraction conversion

* The app places the negative sign next to the number instead of using the negative indicator on the left side of the screen

* The app highlights the last pressed operation key
