EasyCalc PPC v1.25f


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.
