Publisher review:Qalculate! is a multi-purpose desktop calculator for GNU/Linux. Qalculate! is a multi-purpose desktop calculator for GNU/Linux. It is small and simple to use but with much power and versatility underneath. Features include customizable functions, units, arbitrary precision, plotting, and a user-friendly interface (KDE or GTK ). Features: - Calculation and parsing: - Basic operations and operators: - * / ^ E () && || ! < > >= - Fault-tolerant parsing of strings: log 5 / 2 .5 (3) (2( 3 5 = ln(5) / (2.5 * 3) 2 * (3 5) - Expressions may contain any combination of numbers, functions, units, variables, vectors and matrices - Supports complex and infinite numbers - Supports all number bases from 2 to 36, time format and roman numerals - Ability to disable functions, variables, units or unknown variables for less confusion: ex. when you do not want (a b)^2 to mean (are barn)^2 but ("a" "b")^2 - Controllable implicit multiplication - Matrices and vectors, and related operations (determinants etc.) - Verbose error messages - Arbitrary precision - RPN mode - Result display: - Supports all number bases from 2 to 36, plus sexagesimal numbers, time format and roman numerals - Many customization options: precision, max/min decimals, multiplication sign, etc. - Exact or approximate - Fractions: 4 / 6 * 2 = 1.333... = 4/3 = 1 1/3 - Symbolic calculation: - Ex. (x y)^2 = x^2 2xy y^2; 4 "apples" 3 "oranges" - Factorization and simplification - Differentiation and integration - Can solve most equations and inequalities - Customizable assumptions give different results (ex. ln(2x) = ln(2) ln(x) if x is assumed positive) - Functions: - All the usual functions: sine, log, etc... : ln 5 = 1.609; sqrt(tan(20) - 5) = sqrt(-2.76283905578) - Lots of statistical, financial, geometrical, and more functions (approx. 200) - If..then..else function, optional arguments and more features for flexible function creation - Can easily be created, edit and saved to a standard XML file - Units: - Supports all SI units and prefixes (including binary), as well as imperial and other unit systems - Automatic conversion: ft yd m = 2.2192 m - Implicit conversion: 5m/s to mi/h = 11.18 miles/hour - Smart conversion: can automatically convert 5 kg*m/s^2 to 5 newton - Currency conversion with retrieval of daily exchange rates - Different name forms: abbreviation, singular, plural (m, meter, meters) - Can easily be created, edit and saved to a standard XML file - Variables and constants: - Basic constants: pi, e - Lots of physical constants and elements - CSV file import and export - Can easily be created, edit and saved to a standard XML file - Flexible, can contain simple numbers, units or whole expressions - Data sets with objects and associated properties in database-like structure - Plotting: - Uses Gnuplot - Can plot functions or data (matrices and vectors) - Ability to save plot to PNG image, postscript, etc. - Several customization options Requirements: · CLN 1.1 - Class Library for Numbers · Libxml2 (>= 2.3.8) · Glib 2.x · Gnuplot 1.7 (optional, for plotting) · GNU Wget or gnome-vfs (optional, for retrieval of exchange rates, not needed if you use the KDE GUI)
