Kalkulator is a powerful yet simple to use calculator and numerical Swiss army knife for Windows (95..XP), 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. Besides, I've seen a number of 5-star programs which were just embarrassing. No names, please...

(If you think Kalkulator is an overkill for your needs, there is a smaller and simpler alternative: check out the Midget sci/eng calculator — you may like it!)
