The Mother of all Calculators, a Swiss Army knife for scientists and engineers. On one hand, this is an sci/eng calculator: evaluates expressions with more than 103 functions (trig and inverse, log/exp, distributions, Euler, conditional, user-defined), unit conversions, physical constants, computer math (binary, octal, hex), function graphs. On the other, Kalkulator provides advanced operations: statistics (mean, s.d., histograms, polynomial regression), column operations on stat data, polynomial roots, linear algebra (with systems of linear equations). Recently added: function extremum search and point or histogram fitting with an arbitrary function. Importantly, the advanced features don't obstruct the basic ones. Disk save/restore, Help file and other niceties are also included.
