NBP Calculator

Aug 20, 2017

This latest version adds many visual and navigational improvements to the NBP Calculator for both sighted and blind users on mobile platforms. We have added Engineering notation as a choice with Scientific Notation, and the results are shown even as you continue to type an expression. History has been added for the formulas that you are working on, but permanent history is not added yet. These improvements make this a very accessible calculator for the blind and visually impaired.
