The Mother of all Calculators, a Swiss Army knife for scientists and engineers. Perhaps the most capable scientific/engineering calculator for Windows. On one hand, this is a calculator: it evaluates expressions with more than 100 functions (trig/inverse, log/exp, statisical distributions, Euler, conditional, user-defined). Expressions are entered in the customary algebraic notation, and then simply calculated. After computing the value, an expression can be modified or corrected, and recomputed at will. There ara also unit conversions, physical constants, computer math (binary, octal, hex), and function graphs included.

For more advanced users, Kalkulator provides less trivial operations: numerical integration and differentiation, interpolaton (linear or cubic spline), statistics (mean, s.d., histograms, polynomial regression), column operations on stat data, polynomial roots, linear algebra (vector/matrix operations and systems of linear equations). Hard-to-find features: systems of non-linear and differential (ODE) equations, multi-argument function extremum search and point or histogram fitting which includes an arbitrary function. Most importantly, advanced features don't obstruct the basic ones. You can use as much of Kalkulator's capabilities as you need, without being hampered by program capabilities you do not need. Disk save/restore, Help file and other niceties are also included. Kalkulator has been evolving on various OS platforms for the last 15 years, being refined and polished through all this time, and its author has more than 25 years of active experience in numerical methods and software development. Wrotniak.net: Kalkulator, The Mother of All Calculators Kalkulator The Mother of All Calculators — Kalkulator Version 2.50 (2005/08/14) — The same version, as a self-installing archive if you are still running Windows 3.1. Kalkulator is a powerful yet simple to use calculator and numerical Swiss army knife for Windows (from 95 to Windows 8), with features making it especially suitable for scientific and engineering users, including students of these disciplines. Anyone with some knowledge of programming can write a calculator program and call it 'ultimate' or 'professional'. And, sadly, almost everyone does that, with results ranging from mediocre to pathetic, but still accompanied with all inflated claims of being 'greatest', 'most powerful' and whatever. I am going to spare you the intelligence-offending blurb. If you are a scientist, an engineer, or a student in need of some serious number-crunching, then you have to check this program out: use Kalkulator for a few days — and then come to your own conclusions. To be sure, try also other programs of this kind. You will be back. Incidentally, Kalkulator received a 5-star (highest) rating from the ZDNet Software Library, as well as a 4-star (highest, again) rating from the PCWin Resource Center — but don't let any reviewer's opinion affect your choice. Your needs and taste may be different, and not all software reviewers have to be wizards of numerical analysis.
