ND0 RPN Graphing Calculator
Platform: iPhone & iPad
Author: Oliver Unter Ecker
Caution: This calculator works with RPN entry (like an HP 28, 48, 49, 50g), as well as with algebraic entry. Switch to 'alg' mode to get a "=" key. This calculator does not work like an ordinary calculator, and is not merely an improved version of the Apple calculator. It's designed for calculator enthusiasts, students, professionals. You'd be an unusual kid (in a good sense), if you used it in school. There're 300 pages of documentation on the app's website. You will have to do at least the "Quick Tour" to make good use of it. -------- ND0 is a highly programmable calculator with graphing abilities. It's the free three stack positions version of ND1, which has an unlimited stack. More than 500 commands operate on numbers, complex numbers, expressions, vectors, matrices, strings, and other types of objects, such as "Chemical Formula" and "Color". Over 2,000 functions result from all type/command combinations. (The "+" key alone has ~20.) The calculator supports RPN and algebraic entry.
