Kalkules Description:

Kalkules is an universal scientific freeware calculator with an amount of untraditional functions, which can be used particularly by high school or university students. It also offers a wide range of tools, which make your calculations easier and faster.

Features:

- evaluating whole expressions ( ex: 5 + 10 / 3 )
- differentiating functions
- drawing function graphs
- calculating with real complex or modulo numbers
- calculating in four number systems: binary, octal, decimal, hexadecimal
- calculating with fractions ( ex: 5 / 2 + 1 / 3 = 17 / 6 )
- calculating with polynomials
- drawing Horner schemes
- evaluation history
- unlimited count of brackets in the expression
- wide range of arithmetic goniometric and hyperbolic functions
- using self-named variables ( ex: radius, volume, ... )
- inserting some of the predefined constants + ability to define your own constants
- inteligent percentage calculations
- and much more...

What´s New in version 1.8 beta:

Improvements:

- Added new tools: unit converter and quadratic equation
- New window with basic prefix values, which can be easily inserted into the expression
- Program can remember the state it was in during the last execution(chosen number set, angle mode, precision, and so on)
- New setting window with more available settings:
- what to insert as new expression after evaluating the current expression and inserting an operator
- what to use as a decimal separator (dot, coma, or the operating systems default separator)
- choosing between mathematical and electrotechnical format of complex numbers (5-2i vs. 5-j2)
- programs default state (the state right after start - chosen number set, angle mode, precision, and so on)
- result notation: ordinary (0,02) or exponential (2E-2)
- the evaluation result can ...
