EasyCalc is a quite known scientific graphing calculator for PalmOS devices, and is now available on Pocket PCs (WM5 and WM6, ARM/XScale only for now, some function limitations in 1.25a).
It has the ease-of-use of the built-in OS calculators, but adds all the features of a top-of-the-line (TI-89, HP-49) scientific graphing calculator except CAS (computer algebra system) and programming (although user defined functions are possible).
Features and Specifications:
- Skinnable like Free42 (this part of the code was reused from it).
- Dynamic language support: Czech, German, Russian, Ukrainian, English, Japanese, Portuguese, French, Italian, Spanish.
- IEEE-754 double precision math routines.
- Algebraic (not RPN) entry.
- Range of values: +/- 1E-308 to +/-1E308 (IEEE 754 double precision); up to 15-digit (user-selectable) decimal precision.
- 150 built-in functions including: trigonometry, complex numbers, exponential, probability, statistics, numerical analysis of functions (roots, derivatives, integrals, intersection), discrete math, digital signal processing, list, matrix, and special (note: in version 1.25a PPC, not all yet is available).
- Unlimited user-defined variables and functions.
- Multipe levels of nested parentheses limited only by available stack memory.
- Multiple screens easily categorize functions (not all yet available in 1.25a).
- "ANS" button (last result).
- Scrolling history.
- Scrolling menu access to user- and built-in functions and variables.
- Angular Units: Radian, Degree and Grad.
- Integer Base Operations: Decimal, Binary, Hexadecimal, and Octal.
- Display Formats: Normal, Scientific and Engineering display modes.
- Automatic parentheses matching.
- Full clipboard support.
- Complex number support in all functions.
- Graphics (not yet available in 1.25a PPC):
- Normal (Cartesian), polar, and parametric graphs.
- Graph up to six functions simultaneously with trace and numerical analysis.
- Graphs have user definable colors, axes, axes labels, range, grid, log and log-log.
- "Table Mode" of graph function values.
- Zoom in/out.
- Live screen scrolling.
- Adjustable graph resolution.
