Calc is an arbitrary precision arithmetic system that uses a C-like language. It can be used as a calculator, an algorithm prototyper and as a mathematical research tool, and it comes with built in mathematical and programmatic functions.
The CALCEPH Library is designed to access the binary planetary ephemeris files, such INPOPxx and JPL DExxx ephemeris files, (called original JPL binary or INPOP 2.0 or 3.0 binary ephemeris files in the next sections) and the SPICE kernel files (called SPICE ephemeris files in the next sections). At the moment, supported SPICE files are:
text Planetary Constants Kernel (KPL/PCK) files;
binary PCK (DAF/PCK) files;
binary SPK (DAF/SPK) files containing segments of type 1, 2, 3, 5, 8, 9, 12, 13, 17, 18, 19, 20, 21, 102, 103 and 120;
meta kernel (KPL/MK) files;
frame kernel (KPL/FK) files (only basic support).
Calcurse is a text-based calendar and scheduling application. It helps keep track of events, appointments and everyday tasks. A configurable notification system reminds user of upcoming deadlines, and the curses based interface can be customized to suit user needs. All of the commands are documented within an online help system.
Mate Calc is the GTK+ calculator application for the MATE Desktop.
rofi-calc is a rofi plugin that uses qalculate's qalc to parse natural language input and provide results.
CalcMySky is a software package that simulates scattering of light by the atmosphere to render daytime and twilight skies (without stars). Its primary purpose is to enable realistic view of the sky in applications such as planetaria. Secondary objective is to make it possible to explore atmospheric effects such as glories, fogbows etc., as well as simulate unusual environments such as on Mars or an exoplanet orbiting a star with a non-solar spectrum of radiation.
This package consists of three parts:
calcmyskyutility that does the precomputation of the atmosphere model to enable rendering.libShowMySkylibrary that lets the applications render the atmosphere model.ShowMySkypreview GUI that makes it possible to preview the rendering of the atmosphere model and examine its properties.
Efficient C++ optimized functions for numerical and symbolic calculus. It includes basic symbolic arithmetic, tensor calculus, Einstein summing convention, fast computation of the Levi-Civita symbol and generalized Kronecker delta, Taylor series expansion, multivariate Hermite polynomials, accurate high-order derivatives, differential operators (Gradient, Jacobian, Hessian, Divergence, Curl, Laplacian) and numerical integration in arbitrary orthogonal coordinate systems: cartesian, polar, spherical, cylindrical, parabolic or user defined by custom scale factors.

This package consists of a Perl module for date calculations based on the Gregorian calendar, thereby complying with all relevant norms and standards: ISO/R 2015-1971, DIN 1355 and, to some extent, ISO 8601 (where applicable).
This package provides tools for working with the basic calculus operations of differentiation and integration. The Calculus package produces approximate derivatives by several forms of finite differencing or produces exact derivative using symbolic differentiation. It can also be used to compute definite integrals by different numerical methods.
The package calculates the age of someone or something in years. Internally it uses the datenumber package to calculate the age in days; conversion from days to years is then performed, taking care of leap years and such odd things.
The calctab package helps the user to typeset a kind of economic table such as invoices, expense notes and liquidation, or other tabular material with a values column. The code computes sum and percentage with floating point numeric methods and builds the render table task.
Calculator is an application that solves mathematical equations and is suitable as a default application in a Desktop environment.
This package is an engine for calculating numerical expressions containing fractions. The numerical value of the expression is calculated with a non-expandable method and displayed in the form of an irreducible fraction or, where appropriate, an integer. This package is intended for educational purposes.
Date::Calc::XS is an XS wrapper and C library plug-in for Date::Calc.
Casual is a collection of opinionated Transient-based keyboard driven user interfaces for various built-in modes.
The calculator and calculus packages define several instructions which allow us to realise algebraic operations and to evaluate elementary functions and derivatives in our documents. The package's main goal is to define the arithmetic and functional calculations needed in the package xpicture, but the numeric abilities of calculator and calculus may be useful in other contexts.

This package adds custom units to the units table in Emacs Calc by fetching exchange rates backends.
Calculator is an application for performing simple arithmetic. It is the default calculator application in the Pantheon desktop.
