Calculate! 4.9.0 + Portable

Calculate! is a multi-purpose cross-platform desktop calculator. It’s easy to use, but provides the power and versatility usually reserved for complex math packages, as well as useful tools for everyday needs (such as currency conversion and interest calculations). Features include a large library of custom functions, unit calculations and conversions, symbolic calculations (including integrals and equations), arbitrary precision, uncertainty propagation, interval arithmetic, graphing, and a user-friendly interface (GTK, Qt, and CLI). Is free software licensed under the GNU Public License v2 (or later).

System requirements:

Windows 7 – Windows 11 (x86 / x64)
option with QT 6.5.1 for windows 10+
version with GTK for windows 7+

Mathematical library

Calculation and analysis:

Basic operations and operators: + – * / mod ^ E () && || ! < > >= <= != ~ & | << >>
Fault-tolerant string parsing: log 5 / 2 .5 (3) + (2( 3 +5 = ln(5) / (2.5 * 3) + 2 * (3 + 5)
Expressions can contain any combination of numbers, functions, units, variables, vectors and matrices, and dates.
Supports complex and infinite numbers
Propagation of Uncertainty
Interval arithmetic
Supports all common number systems, as well as negative and non-integer bases, sexagesimal numbers, time format and Roman numerals.
Ability to turn off functions, variables, units or unknown variables to reduce confusion: for example, when you don’t want (a+b)^2 to mean (are+barn)^2, but (“a”+”b”)^ 2
Configurable implicit multiplication
Matrices and vectors, as well as related operations (determinants, etc.)
Detailed error messages
Arbitrary precision
RPN mode

Displaying results:

Supports all common number systems, as well as negative and non-integer bases, sexagesimal numbers, time format and Roman numerals.
Many customization options: precision, maximum/minimum number of decimal places, complex form, multiplication sign, etc.
Exact or approximate value: sqrt(32) returns 4 * sqrt(2) or 5.66.
Simple and mixed fractions: 4 / 6 * 2 = 1.333… = 4/3 = 1 + 1/3

Symbolic calculation:

For example, (x + y)^2 = x^2 + 2xy + y^2; 4 “apples” + 3 “oranges”
Factorization and simplification
Differentiation and Integration
Can solve most equations and inequalities
Custom assumptions give different results (e.g. ln(2x) = ln(2) + ln(x) if x is assumed to be positive)

Functions:

Hundreds of flexible functions: trigonometry, exponents and logarithms, combinatorics, geometry, calculus, statistics, finance, time and date, etc.
Can be easily created, edited 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: feet + yards + m = 2.2192 m
Explicit conversion: 5 m/s to mph = 11.18 mph.
Intelligent Conversion: Automatically converts 5kg*m/s^2 to 5N
Currency conversion with daily exchange rates
Various forms of the name: abbreviation, singular, plural (m, meter, meters)
Can be easily created, edited and saved to a standard XML file.

Variables and constants:

Basic constants: pi, e, etc.
Many physical constants (with or without units) and properties of chemical elements.
Import and Export CSV Files
Can be easily created, edited and saved to a standard XML file.
Flexible – Can contain prime numbers, units, or integer expressions.
Data sets with objects and associated properties in a database-like structure

Construction:

Uses Gnuplot
Can display functions or data (matrices and vectors)
Ability to save the plot as a PNG image, postscript, etc.
Multiple customization options

and more…
Management includes a complete list of included functions, modules and variables, as well as several examples.

Convenient dialog boxes for functions with descriptions and input of arguments
Creating/editing functions, variables and units of measurement
Easy editing of matrices and vectors
Various tools for fast conversion between number systems, floating point conversion, calendar and percentage conversion (GTK) and period table (GTK)
User-friendly interface for gnuplot
Custom Keyboard Shortcuts (GTK)
Additional text interface with full functionality
and more…
