Kalkulator is a nice, trial version program only available for Windows, that is part of the category Science & education software with subcategory Calculators (more specifically Scientific).
More about Kalkulator
Kalkulator is a fairly light program that doesn't need as much space than the average program in the section Science & education software. It's a software very heavily used in many countries such as Indonesia, Azerbaijan, and Norway.
Since the software has been added to our selection of software and apps in 2006, it has managed to obtain 154,951 downloads, and last week it gained 152 downloads.
The current version of the software is 2.50 and was updated on 10/2/2006. It's available for users with the operating system Windows 95 and previous versions, and it is available in English.
Unit conversion now uses definitions in an external file, which can be modified by the user to add new units or unit categories
Added user-defines physical constants from a file
Improved algorithm used to round graph limits
Balloon hints use the font as selected for the Preferences
Fixed documentation: wrong formula for histogram goodness of fit
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.
