The 2004 0.7.0 release made libqalculate a shared library and introduced the qalc command-line interface, which gave the project a package-manager identity beyond the GUI application. The project saw long quiet stretches followed by renewed development. The official news archive records 0.9.7 in 2010 after a long pause, then a 2016 revival leading to 0.9.8. In 2017, version 1.0 marked increased stability and efficiency, version 2.0 replaced CLN with GMP and MPFR, removed the Glib dependency from the library, and brought a feature-complete Windows build. By the 5.x series, the manual and homepage describe a broad calculator environment: customizable functions, unit conversion, physical constants, symbolic calculations, arbitrary precision, uncertainty propagation, interval arithmetic, plotting, GTK and Qt interfaces, and qalc. ### Adoption history libqalculate became package-worthy because it packages a full calculator brain separately from the interfaces. That lets distributions ship qalc for terminal users, GUI packages for desktop users, and a library for programs that need the same unit and expression engine. ### How it is used Homebrew users normally meet libqalculate through qalc, using it for unit conversions, exact arithmetic, physical constants, date and time calculations, symbolic algebra, and quick terminal math. Desktop Qalculate! users depend on the same library through the GTK and Qt front ends. ### Why package nerds care libqalculate is beloved package-manager material because it is a calculator that behaves like a small computer algebra and unit-conversion system but installs as a normal Unix CLI/library package. Its dependency changes in 2017 are also a good example of a mature scientific desktop project reducing legacy library drag. ### Timeline - 2004: Version 0.7.0 installed libqalculate as a shared library and added the qalc text interface. - 2010: Version 0.9.7 was released after a long period without updates. - 2016: Version 0.9.8 revived development after nearly a decade of little activity. - 2017: Version 1.0 was released, followed by 2.0 with GMP, MPFR, reduced Glib dependency, libcurl exchange-rate retrieval, and a Windows installer. - 2019: Version 3.0 implemented support for the 2019 SI base-unit redefinition. - 2026: Version 5.11 was documented on the project homepage and manual. ### Related projects - Qalculate! is organized around libqalculate plus qalc, qalculate-gtk, and qalculate-qt. It also intersects with GMP, MPFR, libcurl, and gnuplot in the package graph. ### Sources - - - - - - ## Security Notes library-like package without higher-risk signals. - **Geiger risk:** green / low - library-like package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
