Calc - tqt3 win10 calculator clone and more :)

A customizable Windows 10/11 Calculator clone for Trinity Desktop (TDE)

calc is a lightweight, modern and highly configurable scientific calculator designed specifically for the Trinity Desktop Environment (TDE).

Originally created as a visual clone of the Windows 10/11 Calculator using C++ and TQt3, it has evolved into a feature-rich native TDE application, reproducing the familiar Windows calculator interface, calculation logic, history and memory functions while offering extensive customization options.

It provides Standard, Scientific, Programmer, Date Calculation and Statistics modes, as well as built-in conversions for volume, length, mass, temperature, energy, area and speed. The Programmer mode supports binary, octal, decimal and hexadecimal calculations, bitwise operations and bit manipulation.

The interface is highly customizable, with support for different themes, fonts, icons, borders and layouts, including classic and dark styles. Calculation history can be browsed interactively and previous expressions can easily be recalled.

Under the hood, calc uses GMP for arbitrary-precision arithmetic, allowing accurate calculations with large integers, floating-point values and fractions. Resources such as icons, fonts and translations are embedded directly into the binary, contributing to very fast startup times and low resource usage, in keeping with the lightweight philosophy of TDE.

The application currently includes translations for English, French, German, Spanish, Russian and Hindi, automatically following the user's system locale.

.deb package and .qsi packages provided for easy installation.
