ES Calculator N

ESCalc N (Endo Scientific Calculator with Natural Display) is a scientific calculator app developed by Masamori Endo of Tokai University, author of "A Guide to Using Scientific Calculators for University Students and Engineers," to study the user interface (UI) of scientific calculators. It offers features for university students, researchers and engineers to use in their studies, research and professional work, with an interface designed for intuitive operation and fewer keystrokes. Main features • Natural display of fractions, square roots, powers and nth roots • CALC: repeatedly evaluate the same expression with different variable values • Key physical constants based on CODATA 2022 • Trigonometric, inverse trigonometric, hyperbolic, logarithmic and exponential functions • Degrees, minutes and seconds input and display • Conversion between rectangular and polar coordinates • Memory storage and recall, plus user-defined constants • Recall calculation history and edit previous expressions • A choice of CASIO-style and SHARP-style function input We welcome your comments and feedback as we work to make scientific calculators easier to use.
