ATC 2.1.8
English localized overview for Quick Start. Full technical documentation is available in English. English remains the canonical source for exact release and source-code authority.
Open-source C/C++ mathematical engine and Windows calculator for practical numerical and algebraic workflows.
This localized Quick Start covers the practical first steps for ATC 2.1.8 while preserving the documented ATC command syntax exactly.
Use the Windows desktop application for local/offline work, or open ATC Online Alpha to try the WebAssembly build in a browser.
Type one command per line and press Enter. These examples use documented ATC 2.1.8 commands and operators.

exit* explicitly where it improves readability, for example 5*x.mode; use mode to inspect or change it.#0 and #1 in documented workflows.For repeated calculations, place commands in a text file and process them with the ATC TXT workflow. This is useful for teaching material, regression checks, batch calculations, and reproducible examples.
