A simple, fast, and intuitive command-line calculator written in Go for quick mathematical computations.
calc is a command-line calculator written in Go that allows users to perform mathematical computations quickly and efficiently from the terminal. It supports both an interactive shell mode with history and a single-command mode for evaluating expressions, providing a fast, offline alternative to web-based or slower calculator tools.
Developers, system administrators, students, or anyone who frequently works in the terminal and needs a quick, reliable way to perform calculations without switching contexts or relying on internet connectivity.
calc offers a lightweight, fast-starting calculator with a rich feature set, including history access and a wide range of mathematical functions, all while being entirely offline and easy to use directly from the command line.

Starts quickly and works without an internet connection, as emphasized in the README when comparing to slower alternatives like Google or Python.
Provides a REPL-like environment with command history and pasting support, using the terminal package for familiar shell features.
Includes standard operators, trigonometric functions, logarithms, and constants, making it versatile for various calculations, as listed in the README.
Allows chaining calculations using the @ symbol to reference previous results, enhancing productivity in iterative computations, demonstrated in shell mode examples.
The README admits that more functions are planned for the future, indicating current limitations compared to more comprehensive calculators like those with hyperbolic or statistical functions.
Requires Go to be installed on the system via 'go get', which can be a barrier for users not familiar with or unable to set up Go environments.
Lacks support for symbolic math, unit conversions, or complex numbers, which are available in other calculator tools, limiting its use for advanced mathematical tasks.
